Premium Stretch Knit Expander Sleeping Bag Liner

The Sea to Summit Premium Stretch Knit Expander Sleeping Bag Liner does much more than just add some warmth to your sleeping bag. Its polyester and cotton blend is incredibly stretchy in order to move with you while you sleep, vastly increasing your comfort while you camp. An anti-odor treatment resists foul odors to keep the liner fresh, and using a liner means you can cut down on the amount you're washing your sleeping bag. And unlike most anti-odor treatments, this one does not use nano-sized particles so you can machine wash it without any harm to the treatment. Sea to Summit reinforced the seams for excellent longevity.

Great liner!

Used this liner with my sea to summit 0 degree bag. I really liked the texture and feel of the material. Very soft, but not that awful microfiber stuff. I don’t see it adding a lot of warmth. It got down to 30 degrees when I used this. I could not tell much of a difference when I took it out of the sleeping bag. It did a good job keeping my bag clean. It packs larger than I thought it would. That would be the only thing negative. It still packs down small.

Probably good

[This review was collected as part of a promotion.] Looks good, haven't needed it yet. Might be good for really warm nights by itself. Packs light and small.

Great find!

[This review was collected as part of a promotion.] Used for foreign travel. Perfect size. Took up minimal space in luggage & did not add to weight! Easy care!

Economical and HIGHLY functional

[This review was collected as part of a promotion.] I used this for a 2-night hut-to-hut ski adventure in Oregon. This liner was lightweight, compact, and snuggly soft. It felt great, launders well and is a super economical option for keeping a layer between me and the sleeping bag.

Snuggles for days!

[This review was collected as part of a promotion.] Recently got a double sleeping bag and thought a liner would be a great addition! Fabric is so soft and comfortable and on some of the warmer eves in the desert it's all you need. Such a treat to be able to snuggle with my person, and have enough space to move around too!

Great Product - Super summer sleeping bag

[This review was collected as part of a promotion.] I loved this. It's lightweight and super soft and cozy for two people, or extra luxurious for one! It's now also my go to summer sleeping bag in warm climates (Utah, Texas, even New York etc.). Whish the bag it packs in was a bittt bigger and easy to pack in, so I'd give that a 3 star, but the product itself is definitely 5.

Was under the impression that

[This review was collected as part of a promotion.] Was under the impression that this liner would be sewn at the bottom and part way up the sides, it is not, It's a sack, sewn bottom and all the way up the sides. We cut down the sides to within 12" of the bottom to make this work for us. So far the material has not unraveled,

Excellent sleep sack for hot tropical nights

[This review was collected as part of a promotion.] Excellent product! Used on a 17 day trip on the remote islands of Fiji, not steamy nights kept me cool while keeping the roaches, rats, mosquitoes and sand flies off me at night! Worth every penny.

Soft but pillow case is too short

The material of the expander travel liner is soft and comfortable, like a nice sheet. It is so stretchy, however, that it gets twisted around me when I sleep. It almost looks like it has been sewn a little crooked, but I think that is just the material. My biggest complaint is that the extra material for the pillow is not big enough to cover a standard size pillow. I don’t know if that is normal for sleeping bag liners but that doesn’t make sense to me, since it makes it non-functional as a cover for a pillow.
