The ultimate solution to extending the warmth of your sleeping bag, the Sea To Summit Thermolite Extreme Reactor Liner increases comfort without adding excessive weight and bulk to your adventure kit.
Made with 110g/m2 Thermolite® fabric, the Thermoilite Extreme has a spacious design and stretchy fabric to cater for tall and restless sleepers and a drawcord hood to really trap the warmth when the mercury goes south.
THe liner also increases the life of your sleeping bag as they are much easier to throw in the washing machine than your expensive technical sleeping bag.
When I first got this in the post I was highly sceptical as it was so thin I thought it would never do the trick and I would spend the night freezing. Having recently tried it out in temperatures around 4 degree mark it was perfect for winter. I stayed toasty warm the whole night long didn't wake once from the cold. Definitely recommend to anyone who feels the cold easily.
Recently tested this liner on a 3 day trek in Tasmania's south west doing the Mt Anne circuit and it was great it kept me toasty all night. Keen to test it in some proper cold conditions over the cooler months.
Great service yet again Snowys 👍
What is the difference in length between the regular and long sizes?
That's a good question, sorry we haven't made it clear on the website (I'll get that updated). The long is 235cm and the regular is 210cm so that's a difference of 25cm.
Are the dimensions given for these liners in the stretched or unstretched state. I ask as I am 190cm tall and usually get the long version of products like this. It seems strange that the regular size fits people up to 210cm.
I've just double checked for you on the packaging of this product, and this liner is definitely 210cm long. It also says that this liner is made to be 'spacious' so that may explain why it is larger than usual.
