I’ve tried several jackets, but this is hands down the best insulated hoody for climbing I’ve worn. It breathes well and keeps me warm on chilly ascents without bulk.

As someone who hikes regularly, I appreciate the lightweight breathable outerwear design. It’s comfortable for long days and handles moisture much better than my old jacket.

Great value for a cheap water-resistant hoody for men. The fit is spot on, and the insulated hood is a nice bonus when the wind picks up on the trail.
