Rated 5 out of 5 by from Warmer and Cleaner First off I have a very inexpensive 5 degree sleeping bag. I was wearing a base layer, outer clothing and an extra layer of flannel. A thermal rest all season pad. I was cool but not cold. I was at 10,500 ft in Oct in Crestone,CO. The silk layer added about 3 to 5 degrees Fahrenheit. My sleeping bag has stitching all the way through. The silk layer evened out the cold spots and kept the bag clean. There was a layer of ice on the tent when I woke up. Overall I would recommend the liner for someone who was trying to extend their sleeping bag by a few degrees or trying to keep the sleeping bag clean.

Rated 5 out of 5 by from Perfect for Travel, too I bought my Cocoon in 2010 because of its light weight and small size. When I travel I just throw it in my bag. I use it when there is no top sheet provided or I'm in a friend's home and don't want them to have to wash sheets for my 1-night stay. I also use it when it's too warm in a hotel or hostel to use the blankets. I've washed it in the washing machine with no ill effects. It's one of my most valuable travel accessories, not the least of which is it provides assurance I won't need to be grossed out if I end up at a grungy hostel.

Rated 5 out of 5 by from Ounces, Dollars, Comfort - Which comes first? I just bought this to replace one purchased over ten years ago because that last one ripped. A long time ago, after sleeping in my bag for three months straight, I took a sheet, and sewed it into a tapered sack. 18 oz. Well worth the cost, and well worth the weight to not to have to peel the sleeping bag from me each morning after a week on the trail. This one weghs 4 1/4 oz. It is soo much better to rinse out a liner than to rinse out a downbag. The one I bought ten years ago was from an overstock company and cost less. I never saw one available at that price again. This one, aside from the color, is the same item (OK, one weighs 2 grams more than the other) - This weighs less than a pair wool bootsocks! If you take extended journeys, and resent any additional ounces on your back, this is well worth the dollars.

Rated 4 out of 5 by from Useful I've used this silk liner for the last three years on all my backpacking trips. It's soft, yes, adds some insulation, yes, but the best thing about it is that it keeps my bag clean. When I backpack, I am not the cleanest after a couple days. The sweat and grime transfers to the liner, not the bag when I sleep. After the first year, I dyed it brown so it wouldn't look so dirty in the field. It's easily hand washable, and it drys quickly.

Rated 4 out of 5 by from Surprisingly good It was supposedly Spring, yet I figured I'd bring this silk mummy liner along with my lighter weight down bag - just to try it out. I'm glad I did. My bag was rated to 40 F, and the temperature dropped to that. The silk liner made it comfortable, and probably added a couple of degrees of warmth. If it was hot in the Summer- it would be great to use and sleep on top of the sleeping bag. I'll try that next. Unpacking it was easy, but I was surprised in the morning how easily I was able to just stuff it back into its little sack. It's exactly like a magician stuffing a silk handkerchief into his hand. Poof! Gone. When I got home, I unstuffed it, and refolded and rolled it back into the bag. I love its compact size and extremely light weight. I'm planning to walk the El Camino de Santiago in Spain, and I am definitely taking this for use in the pensiones and guesthouses. It's also a nice way to keep your sleeping bag like new by using a liner like this.

Rated 5 out of 5 by from Great for camping and traveling! I have had the mummy liner for over a year. I have taken it on camping trips, it was a great addition to my sleeping bag. I just returned from a month long trip in France. We stayed in FRBO, Hostels and hotels. At the last minute I threw this in my backpack. I do not regret it. After the first week, my friends were extremely jealous of my liner. I will always travel with my liner!

Rated 5 out of 5 by from So silky it's like sleeping in lotion Used on multi-day bike trips. I'm 6'1" and it fits me fine. It added some warmth (~5 deg F as advertised) to my bag during some 30 degree nights.

Rated 5 out of 5 by from Almost perfect Light weight and added warmth to my sleeping bag at a reasonable price. Note- the bag did not come with the girl as advertised in the picture.

Questions & Answers

What is the longevity of this item. I own one. Its 3 years old and has totally disentegrated. I am going to have to replace it. So what is the expected duration. Should this item make it 50 nights? 25 time in the wash?

Asked by: rilo
If you care for it properly, it should last for many more nights than that. I use my liner every time I stay in a hotel, visit a friend, or sleep in my sleeping bag. I rarely wash mine because I sleep in pjs, but when I do, I either hand wash or put in a "delicates" bag in the machine wash. I would never put this directly in the wash without a protective bag because the silk fabric is so thin, I would be worried the agitator would damage it. Hope this helps!

I will be traveling in India during the month of January, the reviews on this produce but only address temperature issues. Is the sheet also good for protecting against bugs and insects or is there a more suitable product?

Asked by: Jmond
This mummy liner is not treated with permethrin and will not protect against bugs. We recommend purchasing a bottle of permethrin separately and then spraying the liner to give it bug protection.
