Military Fleece Union Suit One Piece Base Layer

What Our Gearhead® Experts Are Saying:

"This piece is a go-to for sub-freezing days at camp or early-morning gear setup in the backcountry. It traps warmth incredibly well but still breathes, and the fleece is way softer than I expected."

When temps drop and cold creeps in from every angle, the Military Fleece Unionsuit from Terramar becomes our cozy armor against the chill. Crafted for reliable warmth in extreme conditions, this one-piece layer wraps us in soft, thermal fleece from neck to ankle, making it ideal for winter camping, dawn patrols, or all-day snow removal missions.

Terramar designed this unionsuit with performance in mind—its polyester fleece locks in heat while still allowing moisture to escape, keeping us warm without overheating. The seamless, collarless design layers easily under outerwear, and the secure fit stays in place as we move, making it a trusted companion from the tent to the treestand.
