Good and comfortable liner

I always try to sleep with a sleeping bag liner to protect my down sleeping bags from sweat and oil. I bought this for winter camping and really like it. I would agree with the reviews below that 15 degrees is a bit generou. But I don't think 5-10 degree increase would be out of line. Overall, I like the liner a lot and it doens't seem to be showing any signs of wear despite numerous uses/washes.
Not that great

This liner is alright but it really doesn't add as much warmth as it claims. If you open it up you will see why, you can see right through it. The fabric is stretchy and comfortable but with no zipper or any type of opening you have to shimmy your way into from the top which is annoying. I traded it is for an Alps microfiber liner that weighs and packs about the same, but has a velcro opening about half the length of it which is much much easier to get into and actually adds more that a few degrees of warmth.
Wish I had got one sooner.

I have used this sleeping bag liner a lot lately. I had thought I would only use it to keep the dirt and grime away from the bag. I found out it is great to use to keep the bugs off and add some warmth when a bag isn't needed. I highly recommend this product. My wife has taken it so will be getting another one :-)
Comfortable, not as warm as claimed
Sonja

I bought this for a winter camping trip and used it with a 20 degree bag and a thermarest pad in weather that dropped to around 18 degrees and dry. I was still very cold. However, I found the liner very comfortable and stretchy, so I'm keeping it for warmer weather to protect my bag. But for extra warmth, I don't think it provided much maybe 5 degrees (my bag is cold for a 20 degree bag).
I had a silk liner that I used before. This liner is more comfortable if you move a lot when you sleep. The fabric stretches and moves with you. It seems like it would be breathable in warmer weather.
Not that great.

Ok this liner does help but I found that there is some liner made of fleece that are cheaper and works better. In a middle of camping trip in March above the arctic circle, I was able to compare both liners and I prefer the fleece one.

I use this 95% of the time I'm sleeping in my sleeping bag. It just makes it so much more comfortable. The fabric feels amazing to the skin, and you can wash it when you're done and save your sleeping bag from getting too funky. It probably adds 5-10 degrees of warmth to your sleeping bags rating, but I still like to use it even when unnecessary just because its so comfy. It packs down tiny and weighs almost nothing. I never leave a trailhead without it.

Found the material scatchy. It did strech which was nice but really did not think it added more than 5 degrees. For that amount of warmth I would go with a silk liner which is much more comfortable.
is it a stretchy material?
diane
Member since
is it a stretchy material?
bp2705
Member since
yes. i have the extreme version and its like a thin loose wool sweater in consistency. not constricting like a cotton sheet or something like that.
Love the way it feels.

This review might be a bit odd for some people, but I'm guessing some will get it. I don't like the feel of most sleeping bags against my skin. Never been a big fan of nylon. Of course it is what is and I love backpacking. I use this liner even when I don't need extra warmth just cause I love the way it feels. The extra warmth is a very nice bonus. It definitely adds warmth I just don't know how much extra warmth it adds I've never tested one night, one night without.
I can say that right after I bought this I was messing with it in my truck whilest driving. (Ya, I know 10 and 2.) I had it pulled out of the bag and I put hood up over my head. Even though my cab was a comfortable temperature, my head was sweating within about 5 minutes of having wearing it.
I can also add that on my most recent hike I was of course using this liner in my bag. During the night the liner came down around my waist only covering lower section I felt a slight chill around my chest and and arms. I woke up and pulled the liner back up all the way and was back to be being nice and warm in no time.
So in short I'd buy this again. I'm not sure if really gets as many degrees as the advertisement says, but it does get the job done.
Worth the $$$

I picked one of these up for my 40 degree bag when an early fall trip dropped down into the 30's at night. This liner is light, very comfortable, and warm. I enjoyed the feel of the liner, no sticky silk feeling. At 9oz it isn't much extra weight and in the summer you could use this instead of a bag.
Best camping investment yet
Thomas Jones
Member since
I have used this for camping in the snow 4 nights so far. It kept me nice and warm and the material feels a lot nicer then what the synthetic sleeping bag feels like. The material seems flimsy but after more then 10 nights sleeping in it, it still hasn't ripped.
Can this liner be used as a sleeping bag...
gsmhikerdude
Member since
Can this liner be used as a sleeping bag in the summer? I hike in the Great Smoky Mountains and it ranges from the mid 50's to the low 70's at night. Thanks.
knanier
Member since
Its really a personal opinion. I would use it...yes. But below the mid 50's...I think I'd be cold and would bring an actual bag. I also know that I'm likely to sleep in my long pants and an insulated jacket if necessary. All depends on YOUR style.
Christopher Hood
Member since
You definitely could. I hiked the AT stretch through the Smokies in late April this past year. I brought this liner and my Kelty Lightyear 40 degree bag. The first few nights we had below freezing temps and with both I was toast! As the week progressed the weather warmed and by the last two nights my Kelty was just a little warm, so I slept in the liner on top of my bag. I was wearing a pair of shorts and shirt as well though, but totally think it would work in summer time in the smokies, even at higher elevations. Of course, I do agree that it is a matter of hiker variability and preference.
Easy, Compact Added Warmth
Merebea Danforth
Member since
Honestly I'm skeptical that this will add 15 degrees of warmth, but that's coming from someone who sleeps and generally runs quite cold. This liner definitely adds some noticeable warmth, and it's soft and nice to sleep in. It's also great for any time when you're sleeping in hot temperatures, or to keep your sleeping bag clean.
Does what you'd expect
emc4621746
Member since
I'm using it for warm summer camping in the desert. Works well by itself on hot nights. Haven't had a chance to use it as a liner yet, but I'm sure it will only add a few degrees to my 20 degree bag.
Money!

Bring this with me wherever i go! its small and compact, provides plenty of warmth year round whether used alone in the summer or in your bag in colder weather. Great Product!
love it
thomas smith

lightweight, stuffs into a roll the size of a soda can, and warm. works great as added layer for your winter/fall sleeping bag. in the summer, can double as a bivy.
also keeps the oils off your bag, reducing the need to launder your expensive sleeping bag!
Does this liner have zipper. How easy is...
jef3089125

Does this liner have zipper. How easy is it to get into. I wanna use it for wall climbing but if its to hard to get into its a hassle.
Mads
Member since
No zipper. There's a drawcord that goes around the opening at the top, that's the only opening. You'll have to slip down into it from the top or step into it and slip it up your body.
Great liner
Ethan Frey
Member since
Used this with my 20 degree bag in the white mountain and was able to sleep in just my long johns with -12 degree temps outside. Seems to work great and wicks moisture away from your body. purfect for augmenting your spring and sumer bags for another season!
