As tough as old boots, or an inflatable dinghy
Heavy because of the mad fabric.


The Concept It's hard to know where Karrimor was coming from with the Boma. It's pronounced 'Bomber' by the way, and because our test pack, which we've had since last August is a pre-produciton unit, it actually says 'Bomber' on it, which is very cool. That name was changed for production models, but it pretty much says it all. The Boma is aimed at being the butchest, most heavy duty technical climbing pack out there.

It does that by being made mainly of a fabric called Hypalon. It's a tough, matt black rubbery material that, no kidding, is used to make Zodiac inflatables and is massively strong and abrasion resistant. It's ideal for dragging and hauling over abrasive rock, though bear in mind that the back system, hip-belt and shoulder straps are all conventional items borrowed from the Alpiniste range.

Here's an alternative theory. Hardly anyone really needs that level of toughness in a pack, but the matt, black, post-apocalyptic finish is the last word in macho chic and will appeal to outdoor fashion victims everywhere. Theory partially confirmed by a non-climbing mate who took one look at the Boma's butch backside and promptly bought one for himself.


Features Well, there's the fabric, and the fabric. Otherwise the Boma is very much a recognisable first cousin of Karrimor's classic Alpiniste packs. It gets, for example, the simple SuperCool reticulated-foam back system with removable, stiffened Fformat bivvy pad, extendible lid, compression straps, wand pockets, hip-belt with gear loops etc.

Two features we liked though were the big pocket running down the back of the sac, intended for snow shovels and the like, but equally adept at handling baguettes or waterproofs, and the side access pocket that lets you delve into the entrails of the sac without having to open the lid. One thing we'd change for winter use would be the fiddly upper ice axe straps, chuck 'em and replace with easy to use shock cord, as used by Karrimor on its other technical sacs.


In Action There's no getting away from it, the Boma weighs a ton. The Alpine Lite, which is the same 45 plus 10 configuration tips the scales at 1,600 grammes, that's almost a kilo lighter. You could have a Alpiniste S 60 plus 15 for 200 grammes less and while the S 45+10 weighs the same as the 60+15, you have to be brutal and say that it too is due for a diet.

Two and a half kilos is an awful lot for a 45-liter pack, even an extendible one. So if that's the price you pay, what are the benefits. Well, toughness for one, we've not made a dent in the Boma's Hypalon armour in six months of use, then again we haven't been hauling it up big walls, but we're prepared to believe that it's incredibly tough. Next the fabric itself is waterproof, while the seams aren't taped, short of us diving into a river, the contents have stayed resolutely dry. Which is nice, particularly in the UK.

Otherwise it carries and functions like an Alpiniste, which means it's a narrow, techical sac with a simple but reasonably effective back system. The internal stiffness comes from the removable, malleable foam fformat with built-in metal frame, which is never going to be as supportive as a more sophisticated arrangement when loads get really heavy, but is bearable thanks to the padding and hugs the back for excellent stability in climbing and scrambling situations.

The top extension is handy, though as with all narrow technical packs, you need to think about what to carry up high - sometimes it's better to repack than screw up your balance. The gear loops are handy too and we love the side access zip - yes, we always leave the wrong thing at the bottom of the sac too - and the big back pocket.

We've left the worst till last though, truth is that the Boma absolutely reeks of rubber. Honestly, if it were any bigger you could fit a door to it and open up a fetish club. Sharing a tent with it is, erm, less than pleasant, and climbing and walking partners wear a permanently wrinkled nose in its presence. We thought the odour might fade, but it remains as bad as the day it first arrived at OM Towers and of course, on the hill it follows you around as if it were attached to your back...


Verdict

In a sense it doesn't really matter what we say, there's little justification for the Boma in most people's lives, it's simply too heavy and too butch. But - and it's a big but - if you don't mind the weight and want a technical sac that performs like an Alpiniste, but promises to last a lot longer when rubbed against rocks and will, in normal use, keep its contents reassuringly dry, then this is the cutest puppy in the litter.

It'll also appeal to gearfreakistas - new word, combination of 'fashionista' and gear freak - who will swoon at the matt black butchness of it all, as well as the smell no doubt. And here's a thought, fall off a cliff and the pack will almost certainly survive the experience better than you.

In all honestly, we like it in the way you might like a Land Rover in the middle of London or the idea of going fishing with a bazooka, but unless you're really hardcore, there are few genuine justifications for buying a Boma. There are several tough, durable, technical packs on the market that weigh a whole lot less.

On the other hand, no one's having our's - just stand back and sniff the rubber.

Pushed for time:A technical climbing pack made from the same fabric as zodiac inflatable launches, so it's very tough, very water resistant but unfortunately very heavy as well. Really there's no justification for buying one and the smell of rubber is nose-shrivellingly bad, but it looks great and performs like an Alpiniste, so while there's no real practical reason to own one, it's a bit of an objet d'outdoors art.
