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.
This is a great inner and can't recommend it enough. I have used amy inners, and this is the first that hasn't twisted and constricted me inside my sleeping bag. Not sure about +15 deg but it certainly dramatically improved the comfort on cold nights
I originally ordered a different sleeping bag liner and rang through to Snowy's who immediately assisted with product change. Quick delivery of extremely warm bag liner. Thank you
We went camping in Snowy mts area when temperature was below zero and I could not believe how cosy I was all night! I would recomend it to anyone like me who would be normally waking up feeling cold. Thanks Snowy for wonderful product and brilliant customer service. 😊
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 👍
I can't see anywhere if the liner unzips or is just a bag piece. Thanks!
The Sea to Summit Thermolite Reactor Liners all just have a drawstring around the opening but no zipper. Unfortunately theywon't open like a blanket. You can certaily use it on its own but I'd only advise it for warm summer nights.
Would this liner be suitable to be used as a summer sleeping bag in warm conditions?
Certainly in really warm weather these make a great, lightweight sleepng bag on their own. Just be careful to check the overnight temeratures, I've been caught out once doing this and it got a little cold early in the morning. If in doubt, take your sleeping bag!
Just wondering what the 90cm width tapers to at the bottom?
I've just grabbed a display model of the Sea to Summit Thermolite Reactor Extreme Liner and it narrows down by about 10cm at the foot end. The fabric is quite stretchy, so there is a fair bit of give to it as well.
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.
