Foilswirl 12 Pcs Lap Warmers – Large 16 x 10 in, Adhesive Backing, Air-Activated Heat Up to 8 Hours

Warmth on demand for cold-weather adventures

Winter wind and damp cold can steal warmth, but Foilswirl Lap Warmers are designed to offer dependable, portable heat when you need it most. This 12-piece set features oversized heat packs with adhesive backing and a generous 16" x 10" surface, delivering warmth close to skin or layered under a blanket for added comfort.

Activation is simple and clean: the packs are air-activated and begin heating within 15 to 30 minutes after you open the exterior packaging and give them a gentle shake. You can wear them directly, or peel away the adhesive backing and place heat exactly where you want it. The heat can last up to 8 hours, making them suitable for extended outings or chilly stadium events.

Made from soft non-woven fabric with a clean white finish, these disposable warmers feel gentle against skin and are designed for single use. The large 16" x 10" footprint makes them versatile for hands, knees, or other areas that could benefit from extra warmth while you camp, hike, fish, or attend outdoor activities.
