Toughest Rucksac Ever?

It's matt black, it's rubbery and it's as tough as old boots. Karrimor's Boma might just be the butchest pack ever to hit the rock

Every so often you come across a bit of kit that makes you go wow. Walk into the reception of Karrimor's Accrington HQ and you'll do it several times...

One reason is a cluster of rucksacs from history - the original 1964 Don Whillans Alpiniste sits on one wall, while directly opposite a battered Alpiniste 65 with a scrawled signature turns out to be the very same pack Stephen Venables took to the top of Everest when he made the first British Ascent without oxygen back in 1988, and over there's the elder statesman of Karrimor packs - an original, 1957 Pinnacle.

The first sac that Karrimor ever made, it's a simple canvas tube that looks primitive now, but at the time was a cutting edge development, being longer, closer fitting and more stable than anything else around.

Mad Stealth Sac

The other thing that stops you dead in your tracks is the mad-looking, mega-techy, matt black, futuristic sight of the new Karrimor Boma pack. The one on the wall in reception actually bears the legend 'Bomber', which is how it's pronounced, but Boma is the real name. The misspelling came courtesy of faulty Korean prognostication on a pre-production pack.

What makes the Boma really different is the fabric. Hypalon is a thick, rubbery-feeling material that looks great, but also happens to be massively tough - we reckon it's similar to the reinforcement used by MHW on their mountain gloves. The result is a pack that ought to be one of the toughest rucksacs ever made and looks it too.

Made from three weights of the super-tough fabric - they had to be developed specially for the sac - the Boma's a technical climbing pack closely based on the Alpiniste range, so it gets all the usual stuff like a SuperCool back with Fformat malleable frame, padded hip-belt with gear loops, wand pockets, compression straps and a big haul loop for ease of use with gloves.

On top of that, there's a neat side-zipper entry on both sides of the main compartment and a full-width outside pocket running right down the back of the pack, which should take a snow shovel or several large-format magazines.

It's got a fantastic, heavy duty industrial feel, an interesting, slightly rubbery aroma, and should be ideal for hauling up rough crags or simply hurling down scree slopes. It's available in a 45+10 normal version and a 30+10 ladies fit with re-designed geometry to suit the female frame.

If there's a downside, it's that the heavy material means that the Boma's not exactly light at 2550 grammes and 2250 grammes depending on size, but if toughness is your main priority, you won't be that bothered.

In the shops from next month, prices are £140 for the 45+10 version and £120 for the 30+10. It comes with Karrimor's two-year Gold Star Guarantee, which means they'll repair it free of charge no matter how you damage the pack and might just be the toughest rucksac ever made...

We have a pre-production model on test now - which is great because it's badged 'Bomber' rather than Boma, and we'll let you know whether we manage to destroy it. This one could run and run...

Ok 1. Did Karrimor mean to all it Bomber or Bomba? Which name is the cock up? Bomber is much better IMHO. 2. Ladies version is 30% smaller then mens - that seriously takes the piss. Do women carry 30% less kit? Do they only go with men who carry the rest of their gear? 3. (Just an observation) Hypalon - same stuff Zodiacs and the like are made of. Is indeed very tough, and presumeably waterproof too.

oops left thread notification on

Dan...if you weant to disable the notification then wait till you get a notification email and click on the link to disable it...It works for me. As for the pack size thing, I think the idea behind the pack being 30% smaller is because on average, the ladies have smaller lenght backs and as such will have smaller packs. And FWIW, I think 'Bomba' is kinda cool!

Awww come off it! Jeannie/ Any Other girls out there - what do you reckon? I don't check my e-mail that often and that way seems much more hassle compared to a simple post...
Posted: 22/08/2002 22:08

I thought Bomber was better and said so, they preferred Boma, partly I think because it might be insensitive in some countries. The prototypes with 'Bomber' on were apparently because the Korean factory tried to second guess Karrimor and decided it would end up as 'Bomber' anyway, so they'd save themselves some work. Sounds bonkers I know, but that's what the K guys told me. It smells very rubbery though... Hmmm.

hmmm nice

rubber...
Posted: 22/08/2002 23:49

Any views on the ladies's sizing Jon? Hypalon always smells forever, as anyone who's ever been near an inflatable boat will testify
Posted: 22/08/2002 23:51

Yeah, everyone knows that it's the bloke's job to carry the ropes and any heavy hardware, so it makes a certain amount of sense... But seriously, I take your point. I'm not going to knock Karrimor for producing a women's specific rucksac - and they've done more than just tweaking the harness spacings btw, stuf like the curve of the hip-belt has been altered etc - but I suspect it's something that was developed on the hoof as the project devloped. The good thing is that there's a new Ladies Fit version of the Alpiniste S in a 45+10 size because one of the Karrimor testing team is Nancy Brookes and she specifically asked for one. Most of the thinking behind the smaller capacity will simply be that women have shorter back lengths and consequently if you want to keep a technical sack close fitting and narrow, you end up losing capacity. If you look at Macpac's sacs, they're the same, the capacity varies acccording to the back length. I'd also guess that realistically there's going to be quite a small market for a £120 women's specific, super tough, 30+10 technical climbing pack. Not that that's any excuse, but I'd guess retailers will be shifting more of the men's version. Use it long enough and you'll associate the outdoors with the smell of... rubber. Perhaps there's scope for a whole range of 'olfactory friendly' packs with a choice of aromas, preferably not too 'Magic Tree' though. Ooops, we gone random.

The example I's use is LA (suprise suprise), who pioneered proper ladies fit (lots of changes) with ND. Their daysacs are the same size in ND, though yes the big sacs are smaller by about 10l in ND versions due to size differences. But 45l to 30l takes the pee-pee! Women are just going to laugh when they see it in shops!
Posted: 23/08/2002 08:51

OK on request from Dan I'll chuck my 2 pennorth in... The relative size of the pack Bob and I carry depends on the activity and our level of expertise / qualifications, hang on, I'll give examples. Climbing trip. Bob is a 'proper' climber (SPA/MPA) and I just 'climb a bit' at a fairly easy level. He carries most of the gear, although I did carry the rope on a backpacking trip in May until my bad knee went and then Ben took it for me. (and on my ML-style training trip one of the group had a 'teensy-weensy' rucsac and another didn't feel very well so I carried the rope for 2 days) So, I often carry a rope, Bob carries the rack which is heavier. Fellwalking. This is my forte, so Bob has a little daypac with his lunch and waterproofs in and I have the 40 litre one with first aid kit, survival bag, sleeping bag for winter conditions, extra rations for the whole group etc. Backpacking. Bob and I both have large Lowe packs, but, as stated above, because the ND one is shorter, the capacity is correspondingly less. Having said that, I weigh less than 9 stone with skinny little arms and shoulders and Bob weighs much more and has huuuuge arm and shoulder muscles. If I carried the same weight as him I would be suffering from exhaustion while he would be skipping along. Of course, if we had the same size / strength ratio, it would be a more equal split. How we split it is that he has the tent and I carry the food, wine, guidebooks, crockery and cutlery etc. Obviously as the trip goes on my pack gets lighter as my knee begins to give me gip so that's OK. Understood all that? Good. I'll be asking questions later..... First question - does this sound fair to you MEN?
Posted: 23/08/2002 09:19

Yeah that sounds fair. I think it all boils down to the individuals body weight. My full xbow, with 7ish days of food, will weigh about 3 stone, including the weight of the pack itself. Isn't there a rule-of-thumb, whereby you should never carry more than one third of your total body weight?? I'm 12 1/2, but I know I'd die if I carried 4 stone! These Bomas sound heavy, so you'd get less gear inside for the same effective weight. My xbow's not exactly light - but I wouldn't want to walk around tied to an ejector seat either!
Posted: 23/08/2002 09:52

Yeah, we've always done something similar, because the Minaret is semi-permanently linked fly to inner, it's hard to split for load sharing, so I tend to carry it and anything else that's significantly heavy - ropes for example, while the redhead gets shrinkage stuff like food and personal kit. I have my purist moments when I reckon women and blokes should carry equal loads, but it's all compromise really. If you're going to get analytical, it's variable distribution and the ideal load share is one where both parties are carrying loads that mean they can move happily at about the same pace with about the same amount of effort. That seems reasonable to me and to everyone's mutual benefit.
Posted: 23/08/2002 09:55

Doesn't just go for women either. If you have a group where there is a large variation in size, regardless of gender, then the loads should be divided accordingly. Its much better to move as a group and avoid possible injury due to a macho "carry equal shares" outlook, that igonores physical capabilities. So there. Si(C) Si(C)
Posted: 23/08/2002 10:10

I have to agree with Dan on the size thing, if you want a 70 litre sac, you want a 70 litre sac no matter what back size / genital equipment you have! For it to be women specific has to be down to harness, hip belt design etc. I tend to carry more than Michele but quite rightly as I'm bigger and stronger than her. But no way would she let me carry everything as she accepts her responsibility to carry her own gear, survival bag etc (now if only I could get her to navigate). It makes me spit when I see couples out on the hill and the 'little girly' is carrying sweet fanny adam, even when Sarah comes out with us she'll carry her own waterproof, drink etc (apart from scrambling but that's for safety issues). A tip lads: When your significant other half isn't watching, slip a couple of rocks into your own rucksack. Then say "feel how heavy my sack is dear, I think you'll have to carry a bit more" at the first opportunity surreptitiously discard the rocks... Don't get caught!

Mike.....just hope your good lady aint reading this post! But yea very crafty!
Posted: 23/08/2002 12:54

I'm just making the point that Karrimor have screwed up again with ludicrous sizing. And frankly, while the Bomba is interesting, I don't see streams of climbers returning from mountains with shredded packs and at 2kg+ it's too heavy to be seriously considered. (I recall the lightweight Berghaus Extrem range and the tale of one which fell several thousand feet, only breaking a buckle!)
Posted: 23/08/2002 13:48

Yeh, Mike, we also get our kids to carry their own lunch, drinks and wetties on their backs. Self-reliance. Tim is much bigger and stronger than I am but we want to encourage them not weigh them down. Besides, when I carry the larger pack it is good for my fitness and I feel really light and speedy on a quick trek with small / no pack.
Posted: 23/08/2002 14:20

What amazes/surprises me is that first couple of days of backpacking. On the first day the bag seems too big, too bulky and too heavy (it probably is!) But by the third day you don't really notice it. tsk! humans! aren't we lovely adaptable creatures?
Posted: 23/08/2002 22:31

Just love the feeling of dropping the backpack at the end of the first day and walking around the camp...feeling like an astronaut on the moon!

Posted: 25/08/2002 16:50

A late entry on the women's sizing debate (and I'm afraid I also remember Jollity farm). This is a matter close to my heart, and probably the reason why I let the guys go off to the top of Mont Blanc without me the other week. A third of my body weight is 17kg, and camping stuff, climbing stuff, cold weather stuff and lots of water comes to that or more - I simply couldn't safely climb with all that lot on my back, whereas the guys (all 6ft plus, 80kg plus)could. Women don't carry 30%less kit, there is only so much stuff that you can cut out, and only so much shared kit that can be given proportionately to the bigger members of the group. There comes a point when at 5' 4" and 8st you have to admit defeat. I have a Pod Black Ice, which is 20% smaller than my husband's, but a) a bigger sack wouldn't have fitted and stayed close to my body , and b) I wouldn't have been able to carry it any distance anyway. So I think that in principal women's fit sacks have to be smaller, but 30 +10 is no more than a big daysack. And as women probably take better care of their kit (or get the chance to use it less...?) the demand for a totally bombproof ladies sack has to be pretty small whatever the size. And I totally agree that everyone ought to carry according to their size, weight and ability, so that everyone in a group can keep up the same pace. It seriously pisses me off trying to keep up with the guys sometimes (or in the case of MB deciding that something that is relatively safe for them just isn't for me), but at least I can beat most of them down a ski slope if I want to!
Posted: 29/08/2002 15:35

Boys are a nightmare, stick em in any sort of quasi-competitive situation and they (we?) get even worse, take mountain biking, get a bunch of lads together and the whole thing will metamorphose into a hormone-fuelled, testosterone race from gate to gate. Too horrible for words. You should have made the boys carry your camping gear though, they'd have been competing to see who could hump the biggest pack to the top quickest... On the subject of the Boma, let's just say it has a distinctive, rubbery aroma and appeal all of its own. I reckon quite a few will sell on pose value simply because they look so different and to be honest, fantastic. A bit heavy though.
Posted: 29/08/2002 15:50

Karin (what a lovely name!) thank you for putting in another girl's viewpoint. Sometimes I feel really rotten when Bob carries more than me on a backpacking trip, but I am about the same size as you and once I had an 18Kg pack to Bob's 22Kg (and even then I felt guilty) and until we started eating some of the food and drinking the first litre of wine (a whole kilo in one fell swoop!), I was quite wobbly when crossing streams, my centre of gravity was all effed up. We have improved since then by buying lightweight kit when it's been really cheap so we don't have to lug round a big fleece jacket and bulky, heavy shell any more. On holiday this summer we were doing our usual diving-fest and the instructor guy was whinging about 'When I'm reincarnated I want to be a woman' because one girl on one of the dives claimed to be a wimp and asked if someone would carry out her kit for her (which I don't agree with, actually, she was no smaller than me and I always take my share). He was 6'4" tall with huuuuuuuuuuge muscles and could carry two tanks without drawing breath. What's his problem? I would come back as a man, no doubt at all. I could buy mountaineering boots to fit me, I would be a lot stronger, and childbirth would be a spectator sport. And I could have fun with boobs. Oh, and I know about the 'men work for 40 years and women have years and years off' remarks. I didn't, OK? <rant mode off> <small voice> sorry

I'd come back as a woman, but I'd probably get banned if I said why. 'Use your imagination...'

Sorry to join in so late in the debate, but thought I could offer some insight as to why we at Karrimmor chose the sizing of the ladies fit boma to be 30-40 litres. Pretty much there are anatomical implications for most women, that do limit the sizing of the backs and also the anatomical build of the back systems (sorry if I'm being too obvious). However, that didn't come into play too much here, as the Alpiniste 45+10 is available in a ladies fit option (as Jon rightfully pointed out). The main reason for the sizing was down to the proportions of men versus women that purchase our climbing packs in various sizes over the past twelve years or so. We find that even when we have offered larger sizes of climbing packs to women, they choose to purchase the smaller size. The main debate we had was whether or not to do the Boma (in both sizes (as the 30+10 is also available for men))and the Alp S 45+10 in womens fit. Long story short, we tried to offer something to both camps (women who prefer to carry larger loads and women who prefer smaller packs) by doing the Alp S 45 and the smaller Boma. Sorry if this came across as "designing" down for women, it was in no way intended to do that. Dan, you mentioned that we had gotten our sizing wrong again... What other packs have we done in sizes that don't make sense to you? Thanks for the input everyone...

Hiya Larry! Karrimor = cool. Do you do anything like: a front mountable (to D-rings on me ruckie) thingy that can double up as: mini-ruckie on its own b*mbag The idea is that the font mountable bit offers access to things that might be needed enroute without having to unload & open main ruckie & give a mini-ruckie for scarmbling climbing (possibly after the tent has been pitched and main ruckie stashed) (and you want to give the waist or hips a rest) & give a bumbag I think the product could have uses but I don't know how widespread Kind regards big bad baga

Hi, the poor long suffering Mrs manic Morley uses the ladies Craghoppers TT45 which she says is great the only downer is that the shoulder straps are a tad wide, my good lady is only 5 ft and 8 and a bit stone so she really is tiny, ladies give these sacks ago.the big plus is the award winning flow motion system great for climbing, srambling and using poles.
Posted: 19/09/2002 21:24

Mrs F has a 55L Craghoppers Dynamic Balance jobbie, and loves it. (She doesn't use it that often mind you but loves it when she does.)
Posted: 19/09/2002 21:27

Yep seen them & shortlisted them. I knocked them off me list when the only ones I could get were black. In a warm climate wiv loads of UV things wrapped in a black bag cook. Y'shoulda seen the cheese we had. MAN IT WAS RUNNY and the smell fph-wah it was gross. The strangest thing was that the cheese tasted really good (smelt attrocious though) BBBaga <|:-)
Posted: 19/09/2002 21:32

ps Larry - can we call the item a: (wait for it) (not far to go now) a baga bag? big bad baga <|:-)
Posted: 19/09/2002 21:34

Pete - I also have a Craggy 40L with flo-motion and I love it, it's superb for scrambling! Agree that the shoulder straps are too wide tho' (I'm around the sams size as Mrs M) but that and the plentitude of straps to flap are my only quibbles. I've never known such comfort in a sac. Black sac? I could have had red (red??!! nooooooooooooooooooo) but I chose black. it's ACE.
