Thaw disposable toe warmers are thin, air-activated heat packs shaped to sit over the toes inside your sock or shoe, where feet get cold first. They have an adhesive backing so they stay in place while you walk, and they start heating soon after the packet is opened, with no batteries or fuel. Stick them to the outside of your sock, not directly on skin. Useful for hunting, fishing, watching sport, outdoor work and long cold drives. They are odourless and single-use. This bulk box holds 40 pairs, enough for a whole season or for a group. Keep unopened packets sealed until needed.
