Sea To Summit 100% Premium Silk Sleeping Bag Liner

Only used it one time so far.It worked for me.I thought it would bunch up,but worked great.It has a place in my pack.

I made the mistake of trying to go cheap and bought a sleeping bag liner that was made out of the same stuff a doctor would cover his examination table with. Very uncomfortable and impossible to get it to fit right in your bag, also packed bulky. I immediately upgraded to this liner. It packs about the size of a pop can, smaller if you put it in a compression sack, and is extremely light. Material feels great next to skin, keeps you cooler in the summer and a little warmer in the winter. The main reason I use it is to protect my bag from sweat and oil, helps protect the fill and the life of the bag. This is one of my must haves.

I love this liner, it comes with me on all my adventures and lives in my carry on bag. Getting stuck at DFW is much more pleasant if you can wrap yourself in silk and pass out under some benches. After (if) I arrive at my destination the liner adds warmth to my sleeping bag and protects it from all the various grime I drag in. Get one, they are worth the price.

This sleeping sack performed as advertised, helping to keep me warm inside my sad, old sleeping bag that's definitely developed a few cold spots. My only caution is that if your clothes are in any way damp, this sack will pick up the moisture and spread it out and you will spend a very chilly, damp and uncomfortable night. Dry off thoroughly before using!

Packs up small, comfortable, easy to use and store and made a real difference in terms of warmth as was sleeping next to glaciers in a bag that wasn't quite warm enough without the liner. Thought it might shift around in the bag or be an annoying fabric against my skin but it was comfortable and didn't seem to bind at all. I just found I had to be careful when getting out of my bag and getting dressed in the tent not to end up with it tucked into my pants and hanging behind me like a piece of overly large tp. Did that twice. Didn't impress anyone! :)

Please see my review "Cocoon Vs Sea to Summit" at the Cocoon COC003 product. There a some key differences to consider before you drop your $70 for this liner. Also, the Cocoon is $10 cheaper

In brief, entry and exit on the S2S is not as user friendly as the Cocoon. Also, the stuff sacks are very different and the zipper on the S2S is troublesome whereas the Cocoons' more traditional stuff sack is much more user friendly.

I believe the quality is quite comparable and the dimensions of each are within an inch or two. Because Backcountry is so consumer friendly, you can do as I and get both to compare and take a closer look before making your final decision.

And remember, when returning ask Backcountry for a complimentary return shipping label. They're very generous with that. Thank you Backcountry!

This thing is pretty sweet. Turns a questionable sleeping area into a place fit for a king. I don't leave home without mine. It also helps extend the life of your sleeping bag. A little pricey though!

Great as a bag liner when backpacking, and so soft I sometimes just wad it up to use as a small makeshift pillow. It drapes close in over the skin trapping a lot of warmth. They are pricey though.

Used this Sea to Summit liner once so far; love how tiny it is. The material is super cool and breathable too.

Doesn't add nearly as much warmth as I expected from a silk liner, but it will be great for summer nights.

This liner has a very generous cut - the rectangular one with no hood has plenty of material to pull it up under your head and give you plenty of wiggle room in your bag. So far, I'm quite pleased.

I have used one of these for over a year and just bought one for my son. They are light weight and pack down very small. They are not cheep, but a good investment for anyone with a nice bag.

Our silk liner arrived yesterday and we put it in our new KELTY Supernova 30 3 in 1 double bag. We will use this in our camper van. The Supernova is Super!!

We were surprised and disappointed in the silk liner that there are no loops for attaching it to the bag (none in the bag either) though a short trial showed it to stay put quite well. The real drawback is that there is no slit or partial opening on either side to make it easier to enter the liner. We will attempt to carefully slit the seam a couple feet on each side. As older folk we need to get up once in the middle of the night which will be difficult in a cramped space without the slit.

This liner is beautifully made and the feel of the silk is nice. Colors are attractive though randomly available and generally cannot be specified. Being ripstop bodes well for long-term durability and should avoid fatal snags from travel-worn fingernails and toenails. It is very lightweight and packs small, but I really wish Sea to Summit had not replaced the drawstring pouch with a zippered one. This one takes longer to pack because the liner _just_ fits inside and it takes some careful work to avoid catching the liner in the zipper of the storage pouch.

The liner has no loops at the corners to tie into a sleeping bag or to hang it for drying after washing.

My biggest disappointment -- and the reason for my return -- is the liner does not have a real hood (no tunneled drawstring or cord lock to close the top). Instead, the top of the liner is plain at chest level and the "hood" is simply a semi-circular flap extension of the bottom. It is not large enough to completely line and protect the hood of my sleeping bag, as I had hoped At best, it would just cover the back of one's head. It would be warmer and more effective with a drawstring or elastic across the top at the chest, hood, or both to prevent drafts and to keep it in place when turning at night. The silk built up a really strong static charge just removing it from the storage sack.

As a general liner, it is good and competes well in the market; it just isn't truly a _hooded_ liner and could use a few needed improvements to be truly great.

I just recently purchased this liner to use in combination with a Western Mountaineering long Ponderosa bag and a Thermarest Prolite plus. This puts me about a pound heavier than my previous combination of a ridgerest and LaFuma ultralight. For being a belly sleeper all I can say is why did I wait so long. On a recent Whitney trip, May 8, I entered my bag, despite wearing a down parka, with legs literally chilled to the bone. Within a couple of hours I was so warm that I had to unzipper the bag. The liner worked perfectly to maintain my body heat without ever getting constricting or clammy. In the morning I charged out of the tent and two hours later we were atop Trail Crest. Now, that's a great night's sleep. Do yourself a favor: get a top end 800 rated semi-rec bag and put this liner in it. Just compensate by getting rid of other stuff out of your pack. Can't wait to use it again.

Worth every penny, warm, comfortable and light for backpacking, highly recommend to anyone. protects the larger investment of a good down bag!

I have used this several times in varying conditions. For cold weather, it adds a bit of warmth, and in the summer, I use it alone just to have a cover. The hood is nice and holds my pillow in place. I do agree it is a bit $$, but some things are worth paying for - comfort is one for me.

I purchased this green double/wide silk liner to go with my super fantastic Western Mountaineering sleeping bag. I got the wide/double version for myself..so I can have more room in the bag to move around in and stick my legs out when it gets too hot- without feeling so trapped. The "wide" silk is nice and smooth..I've never used a silk liner before so I tried it out on my regular bed the first night ..it was a little strange at first , but the next morning I said to myself.."Wow this is great.."
So far I've slept about 20 nights with it in my sleeping bag, the silk is tissue thin so the extra width doesn't feel too baggy "for me"..Even when the fabric gets squrunched up in the sleeping bag when fully zipped. it does take some time to get use to getting in and out of liners..NO zipper entrance, just a french seamed bag.
Pack and stuffed really small, Rip stop silk is great (big plus), machine wash and air dry very fast.
My only issue is: It feels short for me and Iam only 5'9..after the first night, I measured it and its only 73 inches wide and 70 inches long (not 73" as stated)
I wish they made the wide longer..once you are in your sleeping bag with this liner. the Liner bag would only rest a little below my chest..so a few more inches (like 6-8 inches) would really make the difference.. otherwise It does keep expensive sleeping bags clean. Hope this help.

so I bought one of these without really taking a good look at the dimensions. When the box came I couldnt figure out where the liner was among several other items...it is tiny when packed, and weighs almost nothing. Got to try it out when the furnace went out last week and the house temps dropped into the 40s...I was able to sleep very comfortably in a very light summer bag when this was added, and the feel next to the skin is great. I bought the hooded mummy version...the hood is totally useless as it has no drawcord or anything and is essentially a flat half moon. Overall a great product, and worth the cost.

I have the travel liner, never thought of using it as a sleeping bag liner. I bought it to sleep in/on during my travels thru southeast asia. I had been told that bed bugs can't bite thru silk, since it's so tightly woven. Worked perfectly, others sleeping without paid the price, not me!

This is a really nice product that easily adds 10 degrees F to the rating of your bag (or that can work as a stand-alone bag in the tropics or indoors). I wish that there was some sort of side opening, as the top entry is slightly awkward, especially in tight spaces (like in a tent). Small and light enough that it's worth throwing in your bag--even if you don't end up wanting it, a camping buddy might not be so prepared or hot-blooded and could appreciate the extra 10 degrees.

This is my second one. Had the first one for 10 years. It keeps the sleeping bag clean, is lightweight and doesn't get tangled even when twist around in your sleep. Funny thing - at these prices, it was less than the one I bought 10 years ago.

Very light and compact, easy to slide in and out of my summer bag when it gets a little chilly. Haven't used it on it's own yet, but I expect it will be just right for warm summer nights.

It really does make a questionable hotel bedding seem comfy and luxurious.

This was a good buy, but we wish that they came as a mummy double. This is great for a flat surface, and non-mummy bags. But we will be purchasing two separate liners in the future.
