Intraknit Thermal Merino Base Layer Hoodie - Men's

What Our Gearhead® Experts Are Saying:

"This hoodie is a beast for cold starts or big climbs. The mapped Merino zones dump heat where you need it and insulate where it counts. It fits close, layers smoothly, and the longer collar seals in warmth under a helmet—total game changer for alpine missions."

We grab the Intraknit Thermal Merino Base Layer Hoodie when our cold-weather pursuits demand movement, moisture control, and technical layering without compromise. From bootpacks to skintracks, its mapped construction keeps us warm without holding us back.

Smartwool’s Intraknit™ tech blends Merino wool with synthetics for next-to-skin performance that breathes, insulates, and flexes with us through high-output pursuits. 3D mapping provides mobility-focused zones that reduce bulk while increasing comfort. The helmet-compatible hood and tall collar boost coverage without added layers, and thumbholes lock it in when we're on the move. Seamlessly knit mesh zones ventilate heat so we can push harder, longer.
