48h Refill - Backpacker (Pack of 12 M48X Repellent Mats)

Head out on an expedition with peace of mind and keep mosquitoes at bay!

The 48-hour Backpacker refill (12-mat pack) from Thermacell extends your peace of mind during treks, bivouacs, and expeditions in vans, campervans, or motorhomes.

The Thermacell M48X refill pack is specially designed to power your Thermacell MR-BP Backpacker portable repeller.

With its 12 high-performance repellent mats, each offering 4 hours of run time, this kit guarantees you up to 48 hours of total protection against biting insects, even in the heart of the wildest nature.

Each mat is activated by the gentle heat diffused by your stove/Backpacker repeller connected to its gas canister (EN417 standard). It creates an invisible 15 m² shield around the campsite, with no loss of effectiveness over time.

Unlike sticky sprays, this technology is not applied to the skin and produces no smoke, no odor, and no flame. It is a safe, DEET-free formula:

Its effectiveness has been scientifically proven: formulated with D-Cis allethrin (21.97%), it is EPA-rated and effectively repels all species of mosquitoes, including the most aggressive ones (vectors of Zika, West Nile, and encephalitis viruses).

Designed for hikers, campers, and long-distance travelers, the mats are packaged in ultra-compact airtight packaging that takes up negligible space in your backpack. This seal ensures perfect preservation of the active ingredient for several seasons, even if you don't use all the mats immediately.
