Sleep comfortable and temperature perfect thanks to the lightweight warmth of the Mountain Designs THERMOLITE sleeping bag liner. Enhance your sleeping bag by boosting the temperature rating thanks to 130g/m² THERMOLITE construction for warmth and breathability. The mummy shape minimises cold air pockets, and the draw cord in the hood allows you to further trap body heat and with a contrasting colour along the top edge, it makes it much easier to find an opening. With an included foot box at the bottom of the liner, keep your feet extra warm and toasty as well as allowing for a more comfortable fit. The liner packs easily into its own stuff sack, allowing for simple storage and it will take up less room thanks to the compatibility of the liner. Making sure the liner stays clean has never been easier. The anti-microbial treatment means you can use it more often before needing to wash it thanks to it being odour-free. When you do, it's machine washable and quick drying, so you can use it quickly after being washed. The Mountain Designs Thermolite Sleeping Bag Liner is the perfect accompaniment to your outdoor adventures, allowing you to camp in the colder weather knowing you will be kept warm and comfortable, knowing you will be able to stay clean and hygienic thanks to the design of the liner.
