Perfect addition to alpine kit - Mammut Rime Light Insulated Flex Hooded Jacket - Men's

Summary:
1. Perfect specs for alpine kit
2. Forams not insulated = good thing
3. Awesome hood
4. Awesome pockets

1. Was a pleasure to wear up the Sharkstooth in RMNP. Alpine start temp was 40 degrees and I did not feel cold nor feel sweaty the entire approach to the base or on the climb. Near the top winds were pretty strong but the jacket cut the bite nicely! I say perfect addition to my alpine kit because of its additional insulated warmth, wind-blocking ability, water repellency (it did rain), and breathability when paired with my always-on R1. I think a heavier active insulating jacket like the nano air or proton LT would have been too warm on the approach hike with a pack full of gear. I lent my belay jacket to my partner on the climb so the belays were a bit chilly at times higher up but never miserable. My other partner had a light fleece and a windbreaker and was miserably shivering the whole time. If I had the belay jacket, the R1, the Rime light IN, and the belay jacket would have kept me the perfect temp the whole time and maybe even too warm.

2. Also, the forearms are not insulated which I love. I don't really need insulating there and I find that that is where I feel the most clammy and sweaty if I do build up a sweat. It also allows the jacket to pack down more and be lighter.

3. The hood is great too. Fits awesome over a climbing helmet but is also the best fitting helmet-compatible hood when just worn on my head directly when sinched. It is not insulated just FYI, which is not a problem for me since when it's over my helmet, its main purpose is for wind blocking.

4. Pockets are great too. Great height and large. Very usable when wearing a harness and backpack. More so than chest pockets.
