Buying Guide

Choose the right fabric

Merino wool offers natural odor resistance and temperature regulation, while heavyweight cotton or blends provide extra warmth for low-activity cold weather

Check weight and thickness

Heavier-weight or labeled 'heavyweight' shirts trap more heat for low-activity wear, while lightweight knits layer better under jackets

Prioritize odor and moisture control

Look for merino or treated fabrics that wick moisture and resist odors for multi-day wear and travel

Pick the right fit and sleeve length

A snug base-layer fit improves insulation and layering, and choose long-sleeve for insulation or short-sleeve for versatility

Consider construction and details

Features like henley necks, flat seams, and reinforced cuffs affect comfort, mobility, and style under outerwear
