Haago REUSABLE HAND WARMERS Hand Warmers

Haago Reusable Hand Warmers are chemical hand warmers designed for outdoor activities and event distribution. They activate by natural oxidation when exposed to oxygen and can be resealed after use to preserve remaining heat for later within a limited window.

Main benefits

• Activation without flame or electricity: starts working on exposure to air.
• Fast warm-up: reaches operating heat in approximately 5 minutes.
• Long-lasting heat: provides up to 8 hours of continuous warmth per use.
• Reusable within a window: can be resealed and reused over a 10‑day period.
• Environmentally minded materials: made from biodegradable/compostable ingredients and recyclable at end of life.

Typical use cases include outdoor events, hiking and other cold-weather activities where a lightweight, easily distributed source of heat is needed. Supplied in bulk (20 pack, listed as 20 packs of pairs / 40 warmers total), they are ready to use once removed from their packaging and exposed to oxygen.
