Great For Winter
[This review was collected as part of a promotion.] Worked really well for me in temperatures below freezing. I also appreciate that the material is soft against my skin. My sleeping bag has a foot zipper, which I am glad I was also able to use with this liner.

Side Sleeper
[This review was collected as part of a promotion.] Only used it at home for one night. Because I am a side sleeper. Would love to have center zipper a little longer and only one zipper. The market lacks items for side sleepers. Otherwise no issues. But this should work as a dress when I do laundry as well

We Survived -10°f In New Hampshire: Sea To Summit Fleece Liner Kept Us Warm!
[This review was collected as part of a promotion.] Our Boy Scouts of America troop braved the annual Klondike adventure in New Hampshire, facing temperatures as low as -10°F. Proper layering and quality gear were essential, and the Sea to Summit fleece liner proved to be a game-changer. Combined with a 15°F sleeping bag and a thermal liner, the fleece liner added a noticeable boost in warmth and comfort. It effectively trapped heat, prevented cold spots, and made a significant difference in overall insulation. The soft fleece material was cozy, and despite the extreme conditions, we woke up warm and well-rested. Highly recommend this for anyone looking to enhance their sleeping system in cold-weather camping.
