Hi guys. My first post here and i need a serious advice on my future down jacket. I have some demands that must be cleared. Here goes: - low weight. - must keep me warm even if im only wearing a t-shirt.
Im only going to use this jacket in Denmark during the winter. No expedition or hillclimbing. So far i have three candidates and they are: - Norrøna lyngen down jacket. - RAB Neutrino Plus. - RAB infinity.
Can you give me some cons and pros on these models? Or even recommend other brands/models i might have missed?
I've got both an Infinity and a Neutrino Plus, and I would recommend the infinity unless you're doing some polar or high altitude stuff, it's just too warm and bulky otherwise.
Obviously the infinity isn't as windproof or water-resistant as the neutrino, so you'd have to take into consideration Denmark's precipitation levels, or just wear a waterproof shell. The infinity is much lighter and much more packable, and it gets my first choice these days, as does my rab xenon over its equivalent others in my wardrobe.
The infinity is going for £170 at the moment on Beyond Extreme website, I'd recommend that without a doubt.
I've never had a Norrøna so can't really comment, but in my mind RAB or PHD have it 'sewn up' in the down insulation dept.
if you are going to be wearing it why does it have to be low weight? being warm just wearing a t shirt is a direct function of how cold it is. only you know how cold you feel.
other brands to look at are PHD and alpkit.
you probably won't find lighter than phd. all the jackets are temperature rated.
Haglofs do some stuff which I'd presume to be good and must have a presence in Denmark? Maybe not shipped it yet for this winter as not in visible UK stock yet.
The Norrona one is very good too actually. EB have had some in (UK this is). Not quite a dedicated insulation peice as they've put some features on it like side insulation panels in primaloft to get freedom of movement etc. Stitch through but seriously stuffed, much loftier than the infinity, and a nice primaloft filled hood. Heavier too of course
Really they're all quite different.
This is for camping? If you're after something to keep you warm round town then I'd say none of the above (and probably nothing using down.).
But I'd be especially careful of the infinity with that extra light quantum fabric they're using. Great for its intended technical uses but it really won't be that strong.
SMM has a lovely Haglofs down jacket for sale if all you want is to be warm, got one myself and top quality - 330g of 800 down (eu) and weighs just over 600g. Too hot to trek in so it may suit you. I've seen his in the flesh as it were and it's in perfect condition. Might be suitable for you, I think it's a large. It's got baffles rather than stitch through and is pretty water resistant.
Parky, I don't know the full reasons for the OP but I've had similar problems to solve travelling and working in cold places. If you are active/fit you'll be warm indoors in situations others aren't so tend to be the t-shirt wearer in doors, and yet you'll be going outdoors into winter conditions, plus travelling through airports/hotels and want to have a small hand-luggage. Down jackets meets all these criteria. In answer to that specific problem I felt a down jacket would be too warm and went for a windproof plus a down gilet with warm pockets. That worked ok til I had to pull a roller bag and it was freezing. I cured that problem by shrinking absolutely everything so I could backpack and then hands in pockets and problem solved. I now travel through warm to cold conditions. It is satisfying to see the small 16L under the seat on the flight and not being sweaty with a big coat too big to carry, and being warm enough outdoors.
Additional - I also added some sleeves to turn the gilet into a jacket when hands in pockets not enough. I did look at buying a jacket for when packing for colder conditions but one can have too many tops . The down gilet if I'm heading out into rain I'd wear under a windproof, and if I need an insulaton booster the sleeves ontop. That meant the gilet can be down, and the sleeves must be syntethic. So a compromise.
Another vote for PHD here. Their Alpine Ultra and Yukon jackets are very light and warm, possibly too toasty depending on what you were expecting to do in them. The internets inform me that Denmark isn't that chilly in the winter (zero degrees C average, give or take a few?) so if you're actually going to be active outdoors and not just standing around in the wind, you may find that all of the jackets you listed are overkill.
I use a PHD Minimus (with drishell outer and a hood) as my general UK winter down jacket, and it is almost always too warm to use if I'm actually walking around and I'm pretty certain its a noticably less insulating jacket that the Alpine Ultra or any of the models listed in the original post. It probably isn't any lighter or more compact than the lightweight warmer jackets (eg, PHD Alpine Ultra, but thats already at the bottom end of down jacket weights), but it is ~£100 cheaper!
(and probably nothing using down.).
