Thermacell Backpacker Mat-Only Refill - 48 Hours. This 48 hour refill is specifically designed for the Thermacell Backpacker Repeller. Turn it On, Mosquitos Gone.

For use with the Thermacell Backpacker Repeller
Runs on a backpacking stove fuel canister (not included)
The Thermacell Backpacker Repeller creates a 15 ft x 15 ft zone of protection against mosquitoes without messy lotions or sprays.
It weighs only 4 ounces yet delivers up to 90 hours of protection using a fuel source you already carry—camping stove gas canisters (90 hours from a 4 oz. canister).
You can have an entire evening of mosquito freedom on less gas than it takes to boil a pot of water.
Tested and proven in the backcountry.
Compact, rugged, and effective.
Odor-free and DEET-free.
See for yourself why so many outdoor enthusiasts would never head out without their Thermacell Repeller.
Repellent is a synthetic copy of a substance found in chrysanthemum flowers [Allethrin, a copy of a naturally occurring insecticide]
