SmartWool Reversible Training Beanie

This beanie fits nicely under a climbing helmet. Keeps your ears warm and looks great. The amazing thing is you can still HEAR your climbing partner!

I really like this Smartwool beanie. It's incredibly lightweight, provides awesome warmth for the weight, resists odor and fits amazing. It's pack down super small to fit in any nook, in your pack or pocket. Very low profile, so helmet friendly as well. Nice package!

I love making winter time runs in this thing. wicks moisture well and keeps my bald head warm. I have a big noggin so really couldn't fit it under a helmet but love to throw it on when not wearing my helmet (eating lunch, hiking or skinning)

Great product. Lite and still maintains warm.

Snug yet comfortable beanie that is perfect for aerobic activity and or mild conditions. Packs up very small so you can easily stuff it in any pocket if you do start to overheat.

This is my favorite cold weather hat of all time. Very comfortable on my bald head. Keeps my head warm even in sub-freezing temperatures. And it's virtually weightless and fits in even the smallest pocket when I need to stash it. It is quite simply the bomb.

Excellent piece of gear. I just got done skiing for a week at Snowbird, and I wore it underneath my Giro helmet. It fit like a glove and kept me perfectly warm without sweating too much. Highly Recommended for anyone skiing/boarding who wears a helmet.
