Product Insights
Charcoal Earmuffs Worn Behind The Head Behind-the-head band sits behind the skull, not over the crown. PrimaLoft Gold Eco insulation between shell and lining traps body heat. Spot clean only; do not machine wash or dry. Leaves the top of the head uncovered, so it is not a full hat replacement. At 40 CAD, offers PrimaLoft insulation, wool blend, recycled materials, and a collapsible frame.

Warm ears on commutes and cold-weather outings
These behind-the-head ear warmers are made for staying warm on a morning commute, winter walk, hike, or while skiing, snowboarding, or watching outdoor sports, with a soft Primaloft lining intended for optimal warmth. The adjustable, lightweight frame is designed to fit most adults comfortably, and the behind-the-head style is compatible with hats, glasses, earbuds, and most bike helmets — handy when you want ear warmth without giving up your usual gear.[1,2]
Fold flat and stash them between wears
These behind-the-head earmuffs have a foldable frame that collapses into a compact size, so they can be tucked into a coat pocket, backpack, briefcase, or glove compartment when not in use. That makes them easy to keep on hand for outings like a winter walk or commute, then stow away once you're warmed up.[1,2]
