FIELD ISSUE THERMAL — IRON RANGE BLUE

Built as a working layer, not an afterthought.

The FIELD ISSUE THERMAL redefines what a thermal can be. Heavier and more substantial than traditional base layers, this piece is designed to stand on its own—warm enough to wear solo, versatile enough to layer when the temperature drops.

Constructed from a heavyweight knit, it wears more like a sweater than a standard thermal, offering real warmth without sacrificing mobility. Garment-dyed and pre-laundered, it’s fully shrink-free and broken-in from the first wear, holding its shape and fit through repeated washes.

The cut is modern and intentional. Size down for a cleaner, more fitted look, or stay true to size for a relaxed, boxier silhouette. Pair it with sweatpants or hoodies from our Heavy Fleece series and you’ve got a cold-weather uniform built for long days and colder nights.

IRON RANGE BLUE

A cold, industrial blue inspired by the iron country of the Upper Midwest—rugged, utilitarian, and built for winter.
