Backpacker Mosquito Repellent MRP‑BX

The Thermacell Backpacker MRP‑BX camping mosquito shield is an ultra-compact and lightweight solution specially designed to attach directly to your threaded gas cartridges (EN417 standard) during your bivouacs and vanlife trips.

Specially designed for hikers, campers, and lightweight bivouac enthusiasts, this ultra-compact repellent screws directly onto your standard camping gas cartridges (EN417 standard).

In just 15 minutes, it creates an invisible protection zone of 15 m² (up to 4.5 meters range), ensuring a constant and effective barrier against biting insects around your campsite.

The Thermacell Backpacker redefines portable protection with:

• its featherweight (114 g): With its ultra-small size (9.7 x 5 x 6.7 cm), it takes up minimal space in your gear and is transported in its included water-resistant travel bag.

• Its minimal gas consumption: It offers exceptional battery life with your stove cartridges: up to 90 hours of protection with a small 113g cartridge and up to 360 hours with a 453g format!

• Its effectiveness at altitude: Designed to work optimally up to 2,134 meters in altitude, it accompanies you on all your mountain hikes.

This mosquito shield for hikers offers healthy protection without DEET, odor, smoke, or contact with the skin.

This protection is due to its formula concentrated in D-Cis allethrin (21.97%), evaluated by the EPA and tested in the laboratory. It effectively repels all mosquitoes, including species that carry viruses (Zika, West Nile, encephalitis).
