Filson Waffle Knit Thermal Crewneck Top - Men's Sand, M

What Our Gearhead(R) Experts Are Saying:"This thermal is legit-thick, breathable, and built like it'll last for years. I wore it daily on a recent cold-weather trip and it held up to everything: layering under flannels, hiking in frosty mornings, even just lounging around. The waffle knit traps warmth without overheating, and the heavyweight cotton feels like real quality. It fits a little roomy, which is great for layering."Filson's Waffle Knit Thermal Crewneck Top is a heavyweight staple built for cold-weather layering and everyday wear. Crafted from thick, breathable cotton, the thermal waffle texture traps warm air close to the body while allowing moisture to escape-keeping you comfortable whether you're out on a frosty hike or posted up by the fire. Classic details like ribbed cuffs and a reinforced crewneck hold their shape over time, while the structured cotton build adds durability and timeless appeal. It's a layer we reach for often-under jackets, beneath a flannel, or worn solo on chilly mornings.
