The more I wear this jacket the more I love it! I already wrote a review but the more I wear this thing the harder I find to take it off. It works in such a wide range of weather and feels like it's not there half of the time. Blocked some precip today, but had to bust out the Theta AR when it got really bad. Also I found something cool today, if you fold the hood in to the back of the neck when not in use, it provides a LOT of warmth for your neck. The cut and fit is perfect, you won't believe how warm and light this jacket is. A+ can't wait for more colors for I will get another in the future.

This hoody is very warm, recommend a light base at least underneath though as the stretch fleece on the sides is a little drafty. No big deal though, the draftiness helps when layering, lets you breath and move more. I got one of these in a small, and an Atom SV in a Medium, they layer awesomely, and if I ever needed that much warmth, I'd be real comfy with it on. The Atom LT=200 wt. fleece, but WAY lighter (about 1/3 of the weight/bulk of my TNF 200 wt.), Atom SV=300 wt. fleece (also WAY lighter), I don't think I could layer my 200 and 300 wt. fleece and still be able to move. But these two layer just fine. It works very well as a stand alone also, down to about the 30's. The Atom SV on the other hand, was SUPER TOASTY @ 18F (the lowest I've had it yet).

This jacket also folds in to it's own hood, and can DEFINITELY compress more than that, I would just like to know more about coreloft resilience before I go mashing it down to a pea.

btw I got the lichen, what a great color!

I usually wear medium, but since this is a baselayer I opted for the Small and it fit's perfectly, you may want to try a size down for a more snug, next-to-skin fit. Very warm and comfortable for such a thin layer, perfect and worth the money. I would rather have one of these than have 3 of any other brand, but I liked it so much I bought a second. I can't wait to get the bottoms. Please note that the Graphite does not have an orange zip, only the zip tab is orange, the zipper track is graphite.
