Durable: Resists snags and tears better than comparable ultralight fleeces.

Popular with runners, fastpackers, and anyone moving hard in the cold. Best worn under a wind or rain shell — Octa breathes so well it offers almost no wind resistance on its own.

This is a delicate fabric and must be treated as such. It will snag easily, so keep it away from Velcro, dog claws, and bushwhacking. Machine wash cold and hang dry.

This will be a great base layer for this winter, its a little warm for warmer weather. When I'm out hiking in the cold I start peeling off layers as I heat up and I always used a silk base layer which is a little thin when its below freezing, this will be perfect.
I love this hoodie! It's a great lightweight base layer that compacts small, fits in my running vest, and stays warm in damp weather.
This is a great addition to my kit. I had the opportunity to wear it on a cold wet day - used it as a mid layer - and was perfectly warm without overheating. I was birding, which involves a lot of short walks then standing still for a while to hear and see the birds. I didn't get too hot while walking and stayed warm when observing - perfect! I also like that the octa fabric is less prone to snagging than alpha. I feel like I could take off my outer layer if needed and not run the risk of snagging my top on a random bush.
Top fit 👍
I have not used on trail yet but it seems warm
