Balancing weight (9.3 ounces), packability (3” x 5”), and warmth (adds up to 20 Degrees F), the Sea to Summit Thermolite Reactor Compact Plus Liner is a high-performance option for bolstering the versatility of your backpacking or camping sleep system.
The innovative liner utilizes hybrid construction to maximize performance. Eighty gram Hollow core fiber Thermolite fabric is coupled with 110 gram panels at the feet and across the core to address those areas most susceptible to heat loss. The fabric feels great next to skin and is more packable than fleece. A mummy-shape is designed to maintain thermal efficiency and keep weight to a minimum but it also incorporates a footbox to ensure comfort.
The full dimensions of the Sea to Summit Thermolite Reactor Compact Plus Liner are 72” x 36” and it packs down to 3” x 5” in the included sil-nylon stuff sack.

Real Customer Reviews
- Not as warm as advertised, but still perfect for me
Likes: This product does deliver extra warmth and keeps the inside of your sleeping bag clean. I used it each night on a recent trip and was glad I had it.
Dislikes: The product advertises another 20 degrees of warmth. I didn't expect that amount...probably got about 10-15. I was not disappointed because that is what I expected.
- Was looking for added warmth to down sleeping bag. This works great. It's lightweight and compact. Will even use it in warm weather instead of down bag.
Likes: Lightweight, compact, soft against skin, fits well and not too long for 5'4" ht.
Dislikes: Not at this time.
- Nice product creates good warmth
Likes: Soft and stretchy. Adds a close to skin warmth.
Dislikes: Price is a bit high
