    Solid liner

    • Familiarity: I've used it once or twice and have initial impressions

    Good liner takes up about the size of an average mug (and comes with its own little stuff sack) and has a good texture. Rab is also a brand I trust a ton, so while I haven't used it much yet, I know it's a great product.

    Make you bag last

    • Familiarity: I've put it through the wringer

    I have a western mountaineering sleeping bag which was expensive but it was sooooo worth it. I want to make sure it lasts a long time. That’s where the rab silk liner comes in to the picture. It is silly smooth and keeps my smelly feet and dirty body away from my precious sleeping bag when I am smelly and dirty after 5 days of sleeping in the field. It weighs next to nothing. I am critical about my base weight and this is something I always carry along.

    Keep your bag clean!!!

    • Familiarity: I've put it through the wringer

    These are a total necessity for anyone that uses their sleeping bags regularly. Its lightweight, compact and most importantly easier to clean than your sleeping bag. It does add a bit of warmth but I i like to unzip my bag in that case, the silk is quite breathable as well.

    Perfect Sleeping Liner!

    • Familiarity: I've put it through the wringer

    Love this liner! Had a synthetic one before and it gave me a rash; I've been sleeping in this one for 3 weeks straight now and have zero complaints. It has more room than sea to summit liner I had and feels much nicer on the skin. I'm 5'10", 165lbs and I have plenty of room. It does not stretch, but it's no problem since it is quite a bit larger than a typical mummy sleeping bag. Packs up incredibly small and if you put it in your sleeping bag first and then place your sleeping bag in its stuff sack, you won't even know it's there. Highly recommended!

    Sleeping in Silk

    • Familiarity: I've used it several times

    This is a great addition to have for any camping set up. Adds roughly another +/- 5 degrees to the warmth of your bag, is super comfy to sleep in comparing to the inside of your bag, and helps keep your bag free of dirt/grime

    Great addition to my camping setup

    • Familiarity: I've used it several times

    I bought this liner, because I had heard than skin-on-sleeping bag contact was bad for the bag, since dirt and oils can get to the down and pack it down and reduce loft/warmth. I don't like sleeping in full clothing, so a sleeping bag liner seemed to be my solution! I chose this Rab silk liner due to its great optimization of weight/material/design/price.

    Silk is the lightest weight option out there, and this Rab liner feels great against my skin. I also really like the hood, which allows me to either tuck it into the mummy hood when it's cold or tuck around my inflatable pillow when it's warmer. I've washed the liner once, and it was very easy in the machine and dried quickly on a line. It also packs back up into the remarkably small pouch very easily.

    I chose this over the Cocoon mostly due to price and the Rab brand, which is known for quality outdoor products. The only thing I'd change is the color, which for me was the natural silk (I don't understand why you'd do "assorted" colors for a product like this). I'd like something a little darker in case I decided to sleep just with the liner on over my sleeping bag. It's really not that big of a deal, though.

    All in all, this has made my camping sleep situation all the better. I have never slept as well camping!

    Basic silk liner

    • Familiarity: I've used it several times

    This is the first liner I've bought. I have an old 20 degree bag that has a little bit of smell and could use an extra layer. I bought this to do just that. I found that I wasn't that fond of using a liner. I didn't like the extra layer. When I rolled around at night I got tangled up in it. It was good when I used water bottles filled with hot water to add warmth to my bag. I put the bottles between the bag and the liner, so it wouldn't be too hot against me. I'm going to keep the liner, because I got it at such a good price, and it helps with the sleeping bag smell and improved warmth with hot water bottles. I gave it 4 stars because for a liner it's good quality, I just personally don't like liners that much.

    life changing!

    • Familiarity: I've put it through the wringer

    i cant believe i haven't owned one of these before. i am working with disaster relief in nepal, sleeping in destroyed border towns and totally devastated villages. i have slept on floors, dirty mats, in those border towns where rooms feel like brothels. bugs and leeches, villages where everyone has shaved heads or are involved in community lice picking...and this is my best piece! i almost feel like i am in luxury. i just wrap the mummy part over my head when i sleep and 6 weeks into in...i am comfortable still and lice free! traveling between hot hot and not quite a chill seems to good temperature control too.


    • Familiarity: I've used it several times

    Lost track of my Sea to Summit silk liner so got this one for bikepack trips. Does what it’s supposed to. When too warm, basically slept only in the liner and on trips when temps dropped, used it inside a down 800+ fill bag. This fall, at 9000ft, temps got down below freezing (woke up to snow on the ground) but this liner, in a 45degree rated down bag and me in wool from head to to (literally—beanie, long sleeve shirt, tights, and socks) I was able to sleep comfortably (I did keep a hadron down jacket in my bag that I put on after a trip to the bathroom in the middle of the night). Benefit to a bag liner are twofold IMO—likely adds a little additional warmth to a bag and more importantly for me, helps to keep dirt, skin oil and stink from getting on my spendy sleeping bag leaving me to wash the liner periodically and much more easily. Packs small and adds only grams to your kit.

    Purchased for Momma here is her review.

    • Familiarity: I gave it as a gift but have feedback to share

    Took this up to the Wind River Range in Wyoming for four days. I fell in love with it. I will never go camping again without. It kept me very warm. I was able to just use the silk liners at time, and when I used it with my bag I didn't get cold at all. My husband was jealous (guess I have to buy one for dad now) It was light enough that I didn't notice it all. We had to backpack in to our area and this was light enough my husband approved of it being in my pack.

    Roomy, warm, packs well

      I used this liner for over a month in below freezing to zero conditions, coupled with a zero degree rated mummy bag. Unless it was on the colder end of the spectrum, I unzipped my bag halfway and still remained comfortable. Its main value was in keeping the down bag clean - my damp socks, gloves and a water bottle slept with me (as well as my sometimes damp baselayer) inside the liner. When it was extremely cold, I kept my down camp booties on as well, and they usually collected some grunge in the evening before I climbed in. Just shook it out in the morning, and stuffed it in the same sack as the bag. The feel of the liner was more pleasant than that of the bag, but the color was a bit odd - seemed more suitable for the playboy mansion than a down bag in the wild...but that's a quibble.

      Nice silk liner

      • Familiarity: I've used it several times

      Just right, keeps the cleaner, adds a real degree of comfort by cutting down on draft robbing chill, feels great on the skin and only adds 4 oz. to my 2lb. W.M. bag. Plenty of room all over including the feet, very happy.

      A sewn together bed sheet

        Unfortunately this isn't cut as tapered as I would like and there seems to be an excess of material for a regular sized mummy bag. Also the material feels closer to rayon or polyester than silk. A nice unexpected plus is the mummy version sold by Backcountry is the hooded model.

        great silk liner, great price

          I decided to buy this silk liner to protect my MH Ultralamina 32 and Montbell UL Spiral and to add a couple degrees to each. So far I've used the liner for about 60 nights with my Ultralamina 32 and I love it. The liner is very comfortable and smooth to the touch. I'd say it adds a degree or 2 (minimal and just barely noticeable), but my two main reasons for owning this liner are:

          1. It protects my sleeping bags from dirt/oil and helps preserve the life and loft of my bags.
          2. It allows for versatile temperature regulation so I can unzip part of my sleeping bag or cover my or less of my body with the liner to get just the right temperature.

          The Sea to Summit liners are of similar quality but cost about 1.5 times as much. I'd highly recommend the Rab silk liners for their great quality and value. The standard silk liner works well in my mummy bags (and is a few bucks cheaper with a negligible weight difference). It weighs 4.8 oz not 12.3 oz as stated to the right.

          Great value

            I had the opportunity to try out my Rab Silk liner and it worked great. it was a substantial upgrade from my old cotton liner, so much easier to get in and out of. If you are looking for a silk liner don't hesitate.

            How does one specify a mummy model with hood when ordering?


            Up in the drop down where it says "Select style & size" is where you'd do this. Unfortunately at the moment we're all out of the hooded mummy liners for this model.

            Standard rectangular sleeping bag liner

            Long 158g (210cm x 92cm)

            Note that the Traveller has a area for a pillow. Reference this URL for more information:


            Best Answer

            I bought both to compare... here is a little more info:

            The Sea To Summit 100% silk has a stretch panel running the length of the bag liner.

            The Rab has slits in the sides at the top to make it easier to get in.

            I decided to keep the Rab because it seemed easier to get into.

            What's the difference between traveller and standard? I'm looking for the smallest one that is rectangular and silk (non mummy). Which one should I get? Anywhere I can find the specs on these liners?

            It doesn't make sense to me that the Rab cotton sleeping bag liner is the weight of other manufacturer's silk liners, and Rab's silk liner is the weight of other manufacturer's cotton liners. Is the coton really only 4.7 oz? And the silk really 12.3 oz?
