It reminds me of Primaloft insulation in that the warmth/weight quotient is HIGH. It's definitely warmer than my NF Redpoint....no surprise as this jacket has 200g of insulation vs 100g and also has 150g in the sleeves.

I wore this in Tahoe in about 13F with no cold in the least! I could easily go below 0 with this jacket with just a long sleeve merino base or two underneath. As a test, I pressed dry ice on one side to test its insulation. My hand never felt uncomfortable (just like the primaloft of my Redpoint jacket). I've also placed my body in the snow and stayed dry and warm.

The only negative is that the zipper catches sometimes on the side material and the zipper also is somewhat hard to connect at the bottom. Minor annoyances vs its upside.

Material is tough. I snagged it HARD(!!) on my shredded skis. I truly thought I punctured it, but NO(!), it held--the puncture point is barely noticeable. Great ripstop!

I also like the upper fleece neckline and fleeced shoulders. Makes it cozier when putting on. The spandexy sleeve gaskets are also great but is more effy when it goes over a thick sleeve. It would be great to have velcro sleeves also to block out the elements further.

I bought this jacket purely on the looks and the brand name. It has turned out to be a great buy. The jacket is lightweight yet very warm. I love it, and so does my girlfriend, so much so she has taken to wearing it all the time until i get her the women's one. I would give it 5 stars except for the 2 points raised by the previous reviewers. Firstly, the twin zip systems is cumbersome, I have a lot of problems connecting it, to the point of frustration. I have other snowboard jackets with the same zipper system and I don't have half the trouble. Second, would be nice if this was waterproof... that is why 4 stars only.
