Big discovery!

I needed light, warm and very compact for spring thru fall Arc'teryx jackets and this item fits the bill. At only 6oz and stuffing down to almost nothing it is the go anywhere ultra light down jacket, if you think this, a parka think again.

I found the arc'teryx jacket is fine at low altitudes in the summertime but not very good for colder temps even with a shell. The key word is the arc'teryx ultralight - this jacket liner works in conditions that favor an ultralight hiking kit. In more serious conditions, the insulation falls short.

Another arc'teryx shirts are awesome. At less than 8 ounces, it stuffs down to miniscule proportions for easy wear, then puffs back up like it has springs inside. Worn alone it is great for chilly nights in camp, and under a shell it makes the colder nights seem a bit toasty.

This jacket rocks of Arc'Teryx. It is warm yet it will fit in to you back pocket. This is a no frills jacket, no pockets, snaps up the front. Best suited for around town or the in mountains. In the mountains just slide it under your shell and you will be toasty.
