Looking to up the warmth of your sleeping bag? Or maybe you're looking for an ultralight summer sleeping bag? The Sea to Summit Reactor Fleece Liner will happily take care of both.
This technical mummy shaped sleeping bag liner is made from Thermolite® fleece which provides a brilliant balance between warmth and weight. A drawstring hood allows you to trap in extra warmth, especially on those chilly nights. True to its versatility as a standalone warm weather sleeping bag, it has a quarter zip so it's easy to climb in and out.
Packing small in its own Ultra-Sil® stuff sack, the Reactor Fleece Liner is a must for the cold-sleeping mountaineer or the ultralight cyclist or trekker not wanting to carry a conventional sleeping bag.
