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.

I'm 186cm tall. Will it be comfortable fit using a regular size? Otherwise, what dimensions of the long version are?

G'day Nick, 

The regular is 200cm long, so it looks like that's going to be better suited to your height as the long size is 231cm long. I apologise that we didn't have the correct specs for the long size there for you, I'll make sure that get's updated right away Nick.

if you were to use this as a warm weather sleeping bag. What minimum temp would it be rated to?

- Sunny Dunsi(1 month ago)

G'day Jimmy,

Good question but one I don't want to give a definite answer to as we all feel the cold differently! I've used mine as a summer bag in warm conditions and it works well but I've also tried it in milder weather and been quite cold. My advice would be to try it out at home in the sort of conditions you're planning on using it in and if it's not warm enough you can always jump back into a warm bed! If in doubt though, take a proper 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 :)

- Sydney(4 months ago)

G'day Sophie,

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.
