Men’s Merino 250 Baselayer Top - Long Sleeve

Why our Vert Junkies® love this

This is your next-to-skin engine room: 100% merino wool, long sleeve, midweight warmth (250g class). It manages heat when you’re moving, holds steady when you’re stopped, and fights stink when the day goes long. Clean crew neck. Solid knit. Zero fluff.

Key Features

100% pure merino wool construction
Midweight fabric (250g class) for cold-to-cool days
Odor-resistant performance for repeat wear
Temperature regulating merino microclimate control
Moisture-wicking to keep sweat from pooling

Solid color minimalist look that disappears under your kit

Recommended Use

Run it as the base for ski days, cold-weather training, shoulder-season hikes, and travel where you’re packing light and wearing hard. Best in cool to cold conditions with mixed output—add insulation when the pace drops.

Bottom Line

Midweight merino. Long sleeve. All gas, no noise.
