Why We Chose It

A heavyweight winter balaclava made entirely from natural wool, without polyester, acrylic, or nylon. The dense Merino knit provides insulation in freezing temperatures while remaining breathable and naturally moisture-wicking.

Minus33 sources its wool from Responsible Wool Standard (RWS)-certified suppliers, and this balaclava carries OEKO-TEX® STANDARD 100 and Woolmark® certifications. OEKO-TEX certification involves testing for harmful substances (like PFAS), while Woolmark certification verifies wool content and quality standards.
