    Added warmth to sleeping bag

    20 days ago
    [This review was collected as part of a promotion.] My son doesn't usually do winter camping but this year he had to. We bought this liner for making sleeping bar warmer and it served the purpose well. Thanks!

    I had an old one

    [This review was collected as part of a promotion.] I had an old one of these that had seen hundreds of nights of use and was getting worn. I liked that this one had a hood which could retain a pillow. It's a must on cold nights with a quilt and feels like it adds 10-15 degrees to my sleeping warmth. If you're a cold sleeper or use a quilt this is a great buy.

    lives up to expectations

    [This review was collected as part of a promotion.] I just summited Aconcagua. they require a -20°F bag, but wind chills exceeded -37°F. I got this liner for an extra layer of protection and it worked wonderfully. frost would build around the edge of the sleeping bag but I would be warm inside. 5/5*

    [This review was collected as part of a promotion.] Wow, what difference this makes to increase you bag rating. Used in on Kilimanjaro in and out of my bag and stayed nice and toasty without needing to buy a sub zero sleeping bag!

    [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.

    Winning combo for winter Nepal Trek!

    [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.
