Big Agnes  UL Recovery Sleeping Bag Liner

I did a multi day bikepacking trip with plenty of miles each day. The "recovery" bag caught my attention so i decided to give it a try. Works as stated. I felt great each day even with my neighbor snoring in the tent next to me.

i took this liner on a 221 mile bikepacking hut trip. i loved how it felt next to skin, it was a nice layer to have when the hut got too warm for my sleeping bag. and paired with my sleeping bag it was really cozy. i brought the liner to help my legs recover overnight from the long, challenging biking each day. and i have to say, the liner made a difference for me. i was actually amazed at how well it performed for me over the course of the week. i woke up with my legs feeling surprisingly refreshed and recovered.

The liner has become a valued part of my kit since I received it for testing last year. Both on extra cold nights when I need 5° more insulation as well as camping on 80F+ nights when I want some coverage but my main 0° bag is far too warm to tolerate. Y'all know how you need at least one leg under the covers no matter how hot it is? This is perfect for that. I can't speak to the recovery aspects of the ceramic coating as my pre-release liner was simply for durability testing.

I just spent 14 nights in this liner. I wear spandex as a base layer and find that this liner has just the right amount of stretch for movement and stays in place. Most liners end up around my waist, but this one does it's job and keeps my bag clean. It also adds some warmth. I am not sure about the recovery aspect, but for sure it is the best liner I have used in my 67 years.

I found the best recovery came from pairing this with my Big Agnes Quilt and sleeping in a tent for 8 or more hours; I noticed less recovery when I didn't sleep an entire evening in it (I used it during racing to increase the temp range of my quilt.) *I received this item for free.

I ordered a long, but this sleeping bag liner doesn't reach my shoulder blades without pushing my feet through the bottom! I'm 5ft 10.5 in, so a long should reach my head, at least. I liked the material, but cut is narrow overall. I wonder if the wrong size was sent.

I bought this to test the Cellient tech for recovery and healing. I can attest, it does help reduce inflammation and healing to muscle tissue making you ready for the next days exercise. My legs are loose and I require a shorter warm up. I love it.

This sleeping sack is pure magic. I purchased it in advance of a week-long trek and wore it every night. My legs felt great. Kudos to Big Agnes for harnessing the supernatural into a compact, easy to travel with, bag of comfort.

If will purchase a second one before one of these brilliant influencers lets the word out on how miraculous it is and BA tacks a holy tariff on it.
