Extremely Comfortable

[This review was collected as part of a promotion.] I bought this slightly skeptical. I didn’t know if it would be worth the oz and size, but I will be taking it on every trip from here on out. I constantly find my self uncomfortable while sleeping. I have a Exped ultra sleeping matt and an Enlightened Equipment revelation down quilt, but my sleeping system needed one more thing. The fabric used to make the sleeping bag liner was so comfortable and helped me sleep the entire night without waking once. You can feel the added warmth it delivers, and at a decent price compared to most backpacking equipment.

Catches Clothes

[This review was collected as part of a promotion.] I do believe it adds 5-10 deg warmth to my sleeping bag. However, I can't wear anything merino or some others without the liner fabric catch, then as I move the liner twists. Uncomfortable.

Added Warmth To Sleeping Bag

[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*

Toasty

[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!

Love It!

[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!

Slept Like A Baby!

[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.

Sleep Liner

[This review was collected as part of a promotion.] Warm and cozy. Fits well. You get what you pay for so watch for a sale and buy quality.

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.

Was Extra Toasty!

[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.

Bag Freedom

[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.

Great Sleeping Bag Liner

[This review was collected as part of a promotion.] Used the bag liner for a week camping. Worked great. Definitely recommend your Sleeping Bag Liners. Very roomy.

Worked Great

[This review was collected as part of a promotion.] I have a down quilt was getting cold drafts coming in and disrupting my sleep. I actually put the quilt inside the liner and I was super warm

Excellent Liner

[This review was collected as part of a promotion.] The mummy shape is very comfortable, and the materials feel high-quality.
