Made with heavyweight Peruvian cotton. the waffle thermal has a soft feel that's comfortable to wear under a shirt or jacket. The rib-knit cuffs complement and stay in place for easy layering - so you can layer up. or wear it as. The men's crew neck waffle thermal shirt makes both a great base layer or casual long sleeve shirt for day-to-day wear
