Stay cool and protected in the Crater Lake Heavyweight 1/2-Zip Top—breathable UPF 50 comfort
What Our Gearhead® Experts Are Saying:
"I’ve been wearing the Crater Lake Heavyweight 1/2-Zip Top on everything from alpine hikes to sunny crag days. The UPF 50+ fabric keeps me from roasting, and the lightweight knit feels smooth against my skin, even under a pack. I also like how the half-zip lets me dump heat fast when I’m moving uphill."
We never miss a chance to chase bluebird days and early-season warmth, and the Mountain Hardwear Crater Lake Heavyweight 1/2-Zip Top keeps us comfortable from sunrise to sundown. This top is crafted with soft Solar Knit jersey that wicks moisture and shields us from the sun with UPF 50+ protection—so we can hike, climb, and explore with confidence.
The half-zip design makes it easy to vent heat when the pace picks up or layer up when clouds roll in. Low-profile thumbholes add a touch of extra coverage without getting in the way, making this versatile piece our go-to for spring adventures and year-round layering.
