Simply the best silk liner that I have come across.....a real must for thru-hikers.

un peu déçus car il n'a pas une poche pour recouvrir un oreiller.

In warmen Gebieten als Schlafsack genutzt, im Schlafsack um den Schweiß abzufangen oder um ein wenig mehr Wärme zu haben. Dieses Inlet ist unglaublich praktisch und fühlt sich sehr angenehm auf der Haut an.

Let me start off by saying I use mine more than most will. It takes a little getting used to sleeping with a liner. But it is a little bit warmer than sleeping without. It's nice to be able to clean the liner rather than your sleeping bag itself. I can't say how it compares to a less than 100% silk liner because this is the first I've used. This was also one of the only mummy styles I could find. It packs up small and light too. Would be hard to put a second person in, FYI. Think of it as sleeping with sheets or without. Which is more comfortable? So end of the day 5 out of 5 stars.

I took one of these Silk Mummy Liners with me during a bicycle tour to Iceland for some extra warmth in my sleeping bag at night as I camped out. I long debated about whether I needed a liner for my sleeping bag. In the end, I am very glad to have brought this along with me. It ways very little, feels amazing on skin, and provides a nice bit of extra warmth, and there were a couple of nights I really needed it. In the summer, when the whether is warm, this would make for a nice, ultralight sleeping bag. This is an excellent product of great quality. The only drawback is its price. It is a little spendy in my opinion, but top notch.

Great product- this added much needed insulation to my sleeping bag and gave me an extra layer of super soft comfort (which can't be overlooked as one sleeps on the hard wooden floor of a shelter on the Appalachian Trail) AND it's Pretty Too! The bottom is narrow to mimic the style of the cocoon sleeping bag and reduce bulk. The way I found most useful to utilize this was to set up the sleeping bag, partially unzip is. Sit next to the sleeping bag and pull this up over my feet & legs & hips. Then I inserted my freshly Cocooned feet into the sleeping bag and wiggled my way down and into the sleeping bag while pulling the liner up and over my back.Throughout the night as I moved around I would periodically wake due to my shoulder being chilled, why? Because the Cocoon Silk Liner had shifted down exposing my shoulders. As soon as I pulled it back up, I was warm & cozy & ready for more snoozing. TIP: The Mummy Liner has a hood area and I figured out on the second night that I just needed to pull the back ALL the way Up and it no longer slid down my shoulders, it stayed put!.

I slept in this travelsheet for 10 days in a row so visiting friends wouldn't result in loads of wash, wasting time, energy and natural resources. It's really soft and silky, wide enough to be comfortable, and the split in the side makes it so easy to get in and out of (vs my old silk sleeping bag liner, which did not have the side split). It washed and drier-dried beautifully, and the small storage sack is still big enough so it's easy getting it all back in. My only long-term concern is how the silk will hold up since it's lightweight and not ripstop.

The Cocoon Expedition liner is a ripstop silk liner that is designed to go around you before you get into your sleeping bag. Before buying this, I had not used a sleeping bag liner before so I cannot speak to past experiences, but I ended up buying this because I went from a synthetic to a down sleeping bag and wanted to minimise washing of the sleeping bag to preserve the loft of the down.The liner is mummy shaped and very spacious, with no zips or openings down the side so you must get in from the top. Some people consider this a disadvantage, but I do not mind it although I can see how adding a method to open it and enter from the side would be very beneficial. There is a cord to cinch the hood/neck area, and the red stuff sack is sewn onto the front face of the liner so you will never lose it. The liner itself is pretty thin and is actually somewhat transparent, so do not expect the liner to add warmth to your sleeping bag. I did not buy it for this purpose so this factor did not affect my purchase decision. If you wish to add additional warmth to your sleeping bag, this will not be the product for you.The silk feels great and smooth, and in my time using it (2-3 months) I have not experienced any holes or loose threads appearing. Build quality feels really great but because it is so thin I try not to catch it on anything sharp, and I haven't done so yet so I can't report about how "ripstop" it actually is. I used the liner while travelling in Nepal trekking, and it did a fantastic job of keeping my sleeping bag relatively clean. While my sleeping bag did end up smelling a little bad from not showering at all while trekking, the sleeping bag liner smelled a lot worse and I took that to mean that it was actually doing its job. It was also nice having the silky feeling against my bed when I went to sleep. The smoothness of the silk however means that if you tend to roll around inside your sleeping bag a lot when you sleep, you and the liner will roll but your sleeping bag probably will not. I don't know if this is a con or not but it is something to be aware of. The hood was great and the cord cinches down really well, but because you have to constrict through a lot of cord to get it tight around your head, you end up with a massive length of cord that can be a bit annoying if you don't push it outside the liner. Because there is no side access, once you cinch the hood/neck cord it becomes very difficult to move around.The addition of the stuff sack sewed to the front of the liner is also fantastic. In areas where I wanted some extra personal security, such as watching out for my wallet or passport, I could store both of them inside the stuff sack so they would be within my sleeping bag when I slept. You can also keep any other small items you may need in the stuff sack, for example a torch, or batteries to stop them getting killed by extreme cold.In terms of sizing, I am about 183 cm tall (6 foot?) and can fit in the "Regular" size with plenty of room and extra cloth to spare. If you have a tight sleeping bag, the sizing doesn't really matter because the material is so thin and pliable that it will just fill up any spaces that aren't already filled in your sleeping bag.In summary:Pros:- Maintains cleanliness of sleeping bag- Integrated stuff sack lets you store things inside your sleeping bag- Good build quality, seems durable although best not to put it to any hard tests- Hood cinches up really tightCons:- Not for people who are looking to add warmth to their sleeping bagIf this liner was damaged/lost/stolen, I would probably buy it again. I only say probably because I am not entirely aware of the rest of the sleeping bag liner market but as far as my experiences go, this is a great product.

Zuerst gedacht ich hätte das rechteckige bestellt, so war dieses Inlet unabdingbar in Ost-Indonesien. Sehr gute Verarbeitung, optimaler Wärme-Austausch, nimmt kaum Platz auf.

For sure, it is lightweight, and feels great. I couldn't quite get it up over my head; too much wiggling required and not enough room in my women's mummy bag to manage that feat. I'm a short but chunky gal, so the Expedition was a bit too snug for my liking when my arms were straight by my sides. Instead, I pulled it up to my shoulders, tucked my arms inside near my chest, and was very comfortable, as it only feels too narrow around the hip area. There was lots of leg and upper body room (felt downright luxurious puddled around my feet). It turned with me inside the mummy bag, and I never felt twisted up. Could tell a difference if I did not pull it over my arms, so there's for sure an added warmth factor. Used it with a 15+ bag next to a north Texas lake in March for four nights, with overnight temps in the low 50's and slept soundly. Never thought I'd get it back into its little stuff sack, but it went right in without problem. I read a review elsewhere that stated in hot weather it actually felt cooler to sleep with it rather than without due to the bags wicking qualities. Hence, I'm looking forward to using it alone as a summer bag when temperatures soar to 90+ in a few months. Note to ladies: the women's version of the Expedition is NOT ripstop(?!), I called the company and verified. So if ripstop is important, go with this one.
