Gear Notes:
HEAT Factory Hand Warmers
Weight: 45g
Little envelopes of warmth that slip inside your hat or gloves. Once you open the outer envelope, exposing the inner envelope to air, an oxidation process produces heat. The dry chemicals are non-toxic, clean, safe, and biodegradable, for heat without fumes or flames.
These warmers feature a unique "Stop and Go" process for conservation. Placing the warmer in an airtight container (such as a film canister) saves any remaining heating time for use later (preferably within a week). For example, a 12-hour warmer can be used for six hours one day, stored in an airtight container, then used again for approximately six hours another day.
Sold in pairs.
Each lasts up to 12 hours.
Non-toxic.
All contents are all biodegradable: iron powder, charcoal, salt, sawdust, and vermiculite. |
