Sporting a Mummy style with a drawcord footbox, this liner offers both shoulder and base openings for a more temperate comfort; integrated seamlessly with separately available Free-Flow Zip system featured on some separately available Sea to Summit sleeping bags.
Boasting a warm but lightweight construction of knitted, hollow-core Thermolite Pro fibres – featuring infra red technology to reflect your body’s heat back into the bag for enhanced warmth – this liner is the truly temperate addition to your off-grid sleep system, providing a thermal boost for retaining heat. From the sleeping bag to the basecamp hangouts, its knitted fabric offers superior stretch and the freedom to move within bags of various shapes and makes, while HeiQ odour control technology maintains freshness even following prolonged use.
Choose boosted warmth for a better sleep beyond the bedroom, thanks to the Sea to Summit Reactor Extreme Sleeping Bag Liner.
Hi I have a thermolite reactor compact plus liner which i bought from you in 2019. I wonder what that compares with the new models. Thankyou
G'day Verena,
The thermolite reactor comfort plus is about 100g lighter than this one. If weight is a concern, you would be best off going for the Sea to Summit Reactor Sleeping Bag Liner- you should note that one is a bit smaller in both width and height than yours though- max user height of 177 cm. The other models are heavier as they are warmer (thicker), however none are rated at a specific temperature. The heaviest one is the fleece one, which is most comparable in material to the fleece model you already have. All of the newer models are still made using the Thermolite Pro fibres, with the new additions of Sea to Summit's new HeiQ odour control technology and a draw cord at the bottom so that you can walk around while wearing them. There are also zipped arm holes in the warmer models so that you can wear them almost like a jumper. Essentially, the new models are more versatile, but still made with majority the same materials.
Can someone clarify options of this product please. Product selection options are Mummy with drawcord & Compact mummy with drawcord. Description of product says the two options are Mummy with or mummy without drawcord! Which is which or are there four options? Do all options suit with sea to summit sleeping bags?
G'day Rosie,
The only difference between the two is the length.
Compact Mummy is shorter, and yep, they'll fit in any Sea to Sumit sleeping bags.
