The Arctic Trax AT-H100 Thermal Fleece Balaclava seals the gap between your collar and hard hat when the yard drops below freezing. Single-layer brushed polyester fleece traps body heat without the bulk of a two-layer build, the low-profile crown tucks cleanly under Type I and Type II hard hats, and four-way stretch knit lets you drop the face panel for a coffee break and pull it back up one-handed — even in gloves. Shoulder-length drape tucks inside a jacket collar so wind can't funnel down your neck. One size fits adult heads roughly 20–24 inches (men's S–XL, women's S–L). Hi-vis lime for outdoor visibility, deep black for the cab.

Single-layer brushed polyester fleece traps a warm air pocket against your face and neck. Thinner than a two-layer balaclava, warmer than a neck gaiter, and it dries fast after a sweat-through instead of icing up in single-digit wind chill.
02
Tucks under a hard hat
Smooth, low-profile crown with no seam ridges where the helmet suspension sits. Pull it over your ears, drop the hat on top, and the shell rides at spec height — not an inch higher. Works under Type I and Type II hard hats.
03
One-handed face panel
Four-way stretch knit drags under your chin for a coffee break and pulls back up over your nose one-handed. No cords, no cinches, nothing to freeze shut when you’re working in gloves.
04
Seals the collar gap
Shoulder-length drape tucks inside a jacket collar so wind can’t funnel down your neck. The gap between helmet and coat is where heat leaks out first — this closes it.

Size & fit
How it fits.
Single-size thermal fleece balaclava. The 4-way stretch knit fits adult head circumferences roughly 20–24 inches, which covers men’s S–XL and women’s S–L. Works over clean-shaven or lightly bearded faces; longer beards may bunch the chin panel.
How to measure
Head
Wrap a flexible tape around the widest part of your head — across the forehead, above the ears, around the back. One-size-fits-most knit stretches to accommodate adult heads S through XL.
