    Love it!

    4 days ago
    [This review was collected as part of a promotion.] I bought this for a trip up Mt Kilimanjaro and it was such a great purchase! It added a great deal of warmth, I like the way the fabric feels against my skin, and the ability to still walk around wearing it or keep it on when getting out of the tent to go to the bathroom is amazing!

    [This review was collected as part of a promotion.] First test of the liner was a doozy - 13 degrees. But it worked like a champ and gave me that extra warmth to peacefully sleep during the night on the Sheltowee Trace.

    [This review was collected as part of a promotion.] Used this liner coupled with my Spark Sleeping bag and was toasty! Loved having a “blanket” option for inside and outside of my sleeping bag. Was soft and cozy and really made my sleep system versatile.

    [This review was collected as part of a promotion.] This liner kept me very warm on my recent coastal backpacking trip. There was a point where I got a little too warm and moved it bunched up to the side and it was noticeably warmer than the rest of my bag! Highly recommend if you need some extra warmth on a trip.

    [This review was collected as part of a promotion.] This liner is super soft and allows me to finally sleep naked inside my bag without the guilt. Looks super easy to wash. Pairing with a 0 degree bag for winter but will test out as a summer time lite sleeper this year.
