UK-based travel gear company Lifeventure has launched a new range of Sleeplight and Downlight sleeping bags which have all been treated with the company’s EX3 formula that repels mosquitoes, protects against bed bugs and prevents the build up of bacteria.

EX3 has been fully tested by the London School of Hygiene & Tropical Medicine, which performs numerous tests in hot and humid climates. The treatment is said to remain effective for two years, or 35 washes, at which time it can be retreated.
