I have now used this jacket for multiple ice climbing days, some hiking, and just walking to and from work. I am extremely happy with it. It is warm enough to wear in very cold temps (layered underneath), or on top of one layer for a hike in mid 30 degree Fahrenheit temps. The only thing is, I am 5'9", 170 lbs, and the Large is a bit snug, especially with the layers underneath. But, overall, I would highly recommend this jacket!

Warm and comfortable!

This jacket is amazing. Very high quality, excellent fit (I'm 6,0 and 205 pounds and bought a Large). I will wear this with just a t shirt under out and about, and have even layered it under my Snowboard Jacket for extra warmth on super cold days. No more getting cold on the chairlift with this bad boy on!

Great Jacket!

This is a wonderful coat to use as a layer or by itself. I had a pervious version of this coat for the last 4-5 years and it never disappoints! One thing I noticed in this slight redesign, is it is a little bit slimmer around the underarms/rib cage. It probably will be more streamlined as a layer now. I wore my last one so much I'm excited to have a refresh! It had great durability, I just wore it that much!

Fantastic lightweight technical puffy

I love it- I wish I had not gotten a hole in the pocket so quick, but that's easily looked past because of fit, function, and comfort.

Cool jacket!

I wish I had gotten the correct size but these run a little small. The warmth was all there. I also enjoyed the color scheme as well. I'm normally an XL when it comes to size, so I bought an XL jacket. It was just a tad small though. For reference, I'm 6'4", about 215 lbs. And it was tight around the armpits/ shoulders.

perfect hoody for my needs

I love this hoody. I'd love it more if I had a non-hoody jacket version, but it works well for skiing and hiking in Juneau AK. For colder wetter days, it layers well under a shell, and for dryer days it's perfect on its own. The 2-way zipper is perfect for sitting around the campfire and keeping the jacket from riding up on you. Great quality, too. Can't complain about anything really.
