Seems well constructed but "cocoon" is right on
I recently tried this out on an overnight hike and wasn't too impressed. I'm a stout fellow at 6' 1" tall and about 250 lbs, so for me this thing was just way too snug, especially in the leg area. It made my mummy bag seem huge compared to the narrow tailoring of this liner. On a positive note, the liner appears to be made well, and it did add a bit of warmth to my bag. In fact, after about 30 minutes I was so warm and felt so constricted that I took it off and it went back to the store when I returned home. It would probably work fine for smaller framed people, but if you use a large bag and have some size on you, this will likely be a bit too snug.
My Goldilocks liner
This is the third liner I’ve purchased and used extensively, and so far it’s my favorite. There are two things I dislike about liners. First, wriggling into one is a little fussy, especially in the dark. Second, after rolling around a few times, I get tangled up. The microfiber liner behaves much better than either my Cocoon silk liner or my Sea to Summit fleece-like liner. The silk liner is so light and limp it turns inside out and gets wadded up when I exit the tent for a 2 am intermission. The fleece-like liner sticks to me and tangles into a mess. The microfiber material hits a sweet spot. It feels almost like a cotton sheet. The fabric is just stiff enough to make it relatively easy to find the opening, and it’s slippery enough to keep it from tangling instantly. Why do I bother using one at all? I don’t always – sometimes I just sleep in long underwear and socks. When I’m backpacking I like to put some sort of barrier between my skin and my quilt, and I often like a little extra warmth. In warm weather, when I get sweaty in long underwear, the liner lets me sleep naked without getting my quilt nasty. If I can leave the long underwear at home, I save weight and bulk by only taking a liner. This liner has a useful mummy-style hood feature. It does a pretty good job of holding my pillow in place. When I start getting tangled, the hood provides a “this side down” reference point for getting untwisted. The silk liner is lighter, and the fleecy material is warmer, but for all-around livability, this microfiber liner is my clear winner.
great for backpacking alps and europe hostels
I took this liner on a 3-week backpacking trip through Italy. Since I was hiking from refugio (mountain hut) to refugio for the first week, weight was a big concern for me. This liner was very lightweight, and fit my 5'10'' frame well (~130 lbs). The mountain huts in the Italian alps (Dolomites) require you to bring your own liner for sleeping. I bought the liner for this purpose but wound up using it also for the last two weeks in Venice and Rome because I had heard bug bites occur in a lot of Italian hostels, and I felt safer sleeping in the liner on top of the sheets provided by the hostel. I still use this liner on camping trips back in California, and will use it on subsequent international trips.
comfortable fabric and lightweight
I chose this model over some of the other liners for the following reasons: -- The fabric looks and feels like silk: it's not stretchy or sheer. -- In its stuff sack, it's smaller than a liter sized Nalgene bottle. -- It weighs only a little more than the silk liner and half the weight of cotton. -- Simple and functional design: no zippers or flaps to mess with. -- Enough material to easily cover my head if needed: 6' -- Good price/value compared with other options I found this easy to launder. As far as bulk goes, it takes up about as much space as a thin t-shirt. As with many sport synthetics, it comes out of a washer almost dry....and only needed a few hours to completely air dry. As far as added warmth goes, it seems to be similar to a typical bed sheet: for really warm climates, it may be all you need/want. From reading various reviews on this type of product, I found that some people preferred more space, zippers or flaps....but adding that stuff takes up space and weight. Overall, I found this liner to be a good compromise for travel purposes.
Excellent multi-use liner
I use this both in my sleeping bag on camping trips and when sleeping on trains or in shelters of various kinds on my trips. In summer I’ll just sleep in the liner if it is too hot for a bag. It’s comfy, though when I used to use it with a 3/4 zip bag the lack of stretch did mean thar I could get a bit tangled up in it inside the bag at night. It’s a bit heavier and bulkier than silk liners, but much more affordable! I take it on all my travels—an essential part of my adventure kit.
Too thin and too small
I bought this for use as sleeping sheet when camping in Alabama (lows in 70s). I wasn't sure if it would be warm enough, but that wasn't the issue. The problem was that it was *very* tight. I'm an average adult (5'10", 190 lbs) and sleep in a mummy bag all the time, but this was very constricting. If it had a side opening like the cotton version, I probably would've been ok with it. It also wasn't as soft as I was expecting for microfiber -- felt like a cheap bed sheet (very thin).
buy it for comfort, not warmth
I bought this liner primarily to add comfort and warmth to my Big Agnes Cross Mountain 45 deg bag. Although rated as 45 degrees, the bag alone is good to a minimum of 50 degrees on a good night. I needed something to make the slick polyester internal lining feel more comfortable, and add a little warmth. I have used this liner probably 5 times with the bag so far, and just this weekend stretched that same bag to 40 degrees wearing Cap 2 baselayer and this liner. I attribute about half of this temp change to the actual warmth factor of the liner, and the other 5 degrees to not touching the cold feeling polyester lining of the bag. Liner is also very long, and I was able to wrap it completely around my head while still having length at my feet. Material is nothing special, and is quite thin. If you need more than 5 degrees warmth, I would say to look at something else. However, if you just need a liner to add comfort, cleanliness, and is an economical choice... this is it.
No stretch
My wife got this for her first backing trip and didn’t like it because it was too confining. I just thought it was her unaccustomed to mummy bag sleeping, but once we switched I saw what she was talking about. All liners I have used stretch a bit if not a lot and aloe you to fully use the room available in your bag. This thing does not. Very restrictive from the knees down.
Awesome Liner!
Hiked at Philmont in June and used this as my main way to stay warm. Sometimes I used the sleeping bag as a comforter. The liner is super comfy and keeps me nice and toasty.
Bang for your buck
Used this on a bikepacking trip and it was great for the price. Light enough (for the price) and very comfortable. I slept in this on top of my sleeping bag on warm nights (55+F) and added it to my sleeping bag on cooler nights and I was very comfortable. Love the smooth material feeling. If you’re looking for a cheap liner that will do the job, this is it.
