ELOS Thermal offers a reusable heating insole system built for hunters, shooters, and cold-weather users who need dependable warmth without electronics. The trim-to-fit insole holds disposable, air-activated heat packs, eliminating batteries, charging, and common failure points. Customers can replace only the heat packs, driving repeat purchases while keeping the insole in use. For retailers, ELOS delivers strong margins, easy merchandising, and a clear upgrade from single-use warmers and battery-powered insoles. (less)
