Whether you’re out in the wilderness or on the job, staying warm and comfortable is a must. That’s Filson created the waffle thermal. This waffle knit shirt traps a layer of air between the fabric and your skin for enhanced breathability and insulation. 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
