Down Jackets Archives - OutdoorCrunch

The release of Alpha Parka once again revealed the reason why Arc'teryx as a brand is the Apple of the technical outerwear industry. The products they launch are so far beyond today's textile technology that their designs orient the direction of the evolution of jackets.

Alpha Parka (Men's - Women's) is the warmest jacket Arc'teryx has ever manufactured.

Its 296 grams of 800 FP down provides extreme warmth, and makes the Alpha Parka the loftiest Arc'teryx down jacket of all time, standing at 251,600 cubic inches (=296 x 800) of total fill.

On top of that, this absolute unit of a parka is also reinforced with a whooping 90 gsm of Coreloft synthetic insulation, which is extraordinary when you look at the industry standards from this point of view.

As if all these aren't enough, together with its cousin Alpha Lightweight Parka (Men's - Women's), Alpha Parka is also the only Gore-Tex down jackets Arc'teryx has ever manufactured.

I know. Just shot after shot with no pause. Hard to believe how rich this jacket is in terms of performance and capability.

Bring all these together and you get a jacket that almost looks and feels like it's from the future... and of course, a staggering price tag in return.

Quick links:

No other jacket impresses me even nearly as much as the Alpha Parka (Men's - Women's). As long as it's dry and extremely cold out there, it can be counted on without any second thought. Not only is it the warmest Arc'teryx jacket of all time, it's also the only Gore-Tex Arc'teryx down jacket that Arc'teryx has ever manufactured.

It also stuffs into itself and comes with a two way zipper to allow for more comfort and mechanical venting where needed, which makes it one of the most versatile jackets out there (hiking, mountaineering, ice climbing, walking around town, you name it). The only downside to this astonishing item is its staggering price.

Warmth

Arc'teryx Alpha Parka is the warmest jacket Arc'teryx has ever manufactured.

As if 296 grams of 800 FP down wasn't enough, this absolute unit of a parka is also reinforced with a generous 90 gsm of Coreloft synthetic insulation in moisture heavy areas.
