Men’s Merino Wool Baselayer Top Midweight

Why our Vert Junkies® love this

This is your next-to-skin workhorse. Pure merino. Zero blends. Built to regulate heat when you’re moving and hold warmth when you stop. From cold starts to long miles, it stays dry, stays quiet, and doesn’t stink out camp.

Key Features

100% Merino Wool (200 g/m²): Midweight knit for four-season range
Natural Thermoregulation: Warm in cold, cool when you push
Odor Resistance: Wear it longer. Smell less.
Moisture Wicking: Pulls sweat off skin before it chills you
Flatlock Seams: No rub. No hot spots under packs or shells
Next-to-Skin Athletic Fit: Low bulk for clean layering
Tagless Interior: Nothing scratching, nothing catching

Recommended Use

Built for mixed-output days where conditions swing and effort changes fast. Start cold at dawn, grind uphill, cool down on the ridge. Ideal for hiking, hunting, backpacking, travel, and everyday layering in cold weather.

Bottom Line

Pure merino. Midweight muscle. Zero excuses.
