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 shape sleeping bag liner is made from Thermolite® fleece which provides a brilliant balance between warmth and weight. A draw string 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 its easy to climb in and out.
Packing small in its own Ultra-Sil® stuff sac, 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.
Hi Snowys, Could you please tell me the difference between the Sea to Summit Thermolite Reactor Fleece Liner and the Thermolite Reactor Extreme Liner - is one warmer than the other? Many thanks :)
The Sea to Summit Thermolite Reactor Fleece Liner is designed for camping and doesn't have an official temperature rating. It's also made from a fleece material making it a thicker fabric than many other liners. The Sea to Summit Thermolite Reactor Extreme is designed for Hiking and Trekking and has a temperature rating that adds an additional 15C to your sleeping bag. This is made from a thinner fabric to keep weight down.
