The Sleeplight range from Lifeventure are synthetically filled lightweight seeping bags, they have a tapered mummy fit reducing the amount of dead space meaning you use less energy to stay warm & help you get a comfortable night’s sleep. To help with moisture management Lifeventure have constructed this bag with a breathable light weight micro-polyester internal lining. The outer is made from lightweight ripstop nylon with a handy external front pocket & 2 internal security pockets to hide your phone & wallet should anyone try to rob you. As a little bonus Lifeventure have kindly impregnated these bags with their EX3 triple layer treatment. What is EX3 you ask? EX3 is a fabric treatment that helps to prevent the build-up of odours caused by bacteria, which is useful if showers are few & far between; it repels those annoying mosquitos & protects you against the threat of bed bugs. Complete with its waterproof compression stuff sack this bag is a great little travel companion or adventure racing buddy!
