Wouldn't be without it...

Everyone in my family has one of these and we take it every time we camp, whether car or backpacking. It's pretty light and packs to about the size of a grapefruit. After the first night, we just stuff it in with the bag. In warmer weather, I use it alone, just lying on top of the bag. If it cools off in the night, I just slip into the bag. My son drapes it over him like a sheet, but it's not very wide for those of us with larger frames. I always use it as a liner in the bag; it is also more comfortable than the somewhat slick fabric of the bag.

I don't really see how this could be compared to a plastic bag due to how thin the material is--thinner than a regular bedsheet, almost sheer but very durable. We have never torn one. The only way to get more ventilation would be to use nothing. Can't compare to the silk or cotton version since I've never tried these.

In actual use, rather than getting into it, it's easier to "put it on" like a sock or (I'm using my imagination here), panty hose. Highly recommended.

Perfect for overseas travel

I do overseas medical volunteer work in pretty sketchy rural conditions, high heat and humidity. Accomodations are rustic, at times no electricity or running water, and I sleep inside a full mosquito tent with nylon base on top of whatever bed is available. I have used this on 3 weeks-long trips and have slept wonderfully. The sweat evaporates, even between my back and the nylon tent base. I am allowed only one carry-on bag for personal items plus medical clothing plus medical equipment and supplies, so whatever I pack must perform perfectly. This one does. I also use it as a blanket on the plane and while traveling from site to site, and packed up it makes a decent small pillow or back support. Great product.

Very comfortable! Very compact.

In the bag, it's about the size of a 500ml Nalgene only a little bigger around. See the specs for the unpacked size. I've gotten more use out of mine in hotels than I have outside. It seems that no matter how low the A/C is set, all the sheets/blankets/etc. are just too much (for "hot natured" me) so out comes the travel sheet. When hammocking, this is the perfect trade off for those late summer and fall nights where even the thinnest warm weather bag is too much but nothing isn't quite enough. I've also used it as a neck pillow with acceptable results.
Despite the glowing review, I only give 4 stars because this is the only one with which I have any experience.

You will not regret this purchase!

Just got back from a weekend camping and it was high 80's-mid 90's with excruciatingly high humidity- as in sweat would just drip off of me because it couldn't evaporate into the already-saturated air. Sleeping had the potential to be miserable and I was fully prepared to go sleep in my car with the AC running.
Instead, I used the CoolMax sheet with an inflatable air mattress and a little battery powered fan. Make sure to pull it all the way up to your shoulders and neck in the back, then you can tuck it under your arms. It wicked away the sweat and left me cool and dry all night- until I had to get up in the morning!

Perfect for travel!

I originally got this for a trip through SE asia where I stayed at some pretty questionable places as far as cleanliness goes. This was perfect to use in-between the sheets (i get cold...) and made it so i never had to worry about touching a dirty sheet/ blanket. I'm taking it to Panama for a trip where the accommodations are going to be rustic and humid and am confident that it will perform just as well as it did last time I would highly recommend this product!

useful for hiking!

Used this on an REI Adventure trip to the White Mountains in NH in July. We stayed in huts along the way. This was perfect in the bunks at night! Comfortable and cool on a warm night and a great soft layer against my skin under the itchy blankets on a cool night. The best feature is the pocket for the pillow so I didn't have to bring a pillowcase. Stuffs into it's own stuff-sack, making the organization of my pack easier.

A very useful item

I have owned a Coolmax Cocoon for about 5 years. It is great for very warm nights, keeping the drafts off you in a warmer bag on cold nights, keeping the bag clean and best of all, I can use just the cocoon between me and my foam pad and it wicks well enough to keep my back from getting sweaty. That allows me to only need a top blanket instead of a sleeping bag, saving weight in the pack.

Great addition to any sleeping bag

The coolmax liner is a simple way to add some warmth to your sleeping bag. On warm nights its a great cover alone and works perfectly as a "hostel sheet" for traveling in less than spotless bunkhouses. It's also a lot easier to clean than the whole sleeping bag and keeps the full bag from getting as dirty. I have found mine getting a little bit pilly, but is not tearing or wearing through at all. Over-all, a great investment!

Thios Travel Sheet is a great product

I bought these travel sheets for my 13 year old son and I to use for a weekend car camping trip and was very pleased with the added warmth and comfort they provided. In fact, my son loves it so much that he is now sleeping in it at home every night (maybe he just likes not having to make the bed?)

Sleeping like never before ...

This is my new favorite piece of gear. Just used for the first time on a long weekend trip. When it was cold at night, it added much-needed warmth to my lightweight sleeping bag. On a warm afternoon, it gave me just what I needed for a post-hike nap. It's soft and roomy. I won't ever camp without it again!

Negative Reviews:

Not good for use alone in warm weather

R.e. "used alone in warmer weather"

Used instead of a sleeping bag on a summer biking trip, to my regret. The package shows the sheet as closed on 2 1/2 sides but it is really closed on 3 sides - you can't open it up to dissipate heat.

Might be okay in cooler weather but at the height of summer it is like sleeping in an expensive zip-lock bag.
KenOn10 at Campmor on 08/08/2010

Perhaps it is a matter of taste

r.e. "In actual use, rather than getting into it, it's easier to "put it on" like a sock or (I'm using my imagination here), panty hose."

Accurate, but in the summer who is comfortable sleeping in socks or pantyhose? Not me... it seemed clingy and clammy to both me and my wife. I guess it is a matter of taste.

Neutral Reviews:

does what it says it does, not much more

Its a bag liner. Bag liners are good for keeping your bag clean and adding a bit of warmth. I suppose you could use it as a warm weather cover up or a warmer on a train or something. I tried to use it with my hammock on a november morning in Austin, it didnt do the job, I upgraded from it to an REI Travel Sack. So Im not so sure yet about its versatility outside of being a bag liner. As a bag liner though it does its job. If you dont sleep in your cloths a bag liner keeps your bag cleaner and is more comfortable on your skin than the bag alone. if your camping in the cold you can pull the pillow pocket of this bag liner (wich is huge) over your head and face to get a bit of protection from the cold. But then again. if you wear cloths to bed a bag liner is less needed. and if you are a scarf fan like me it doesent help you quite as much when its cold, not that I didnt indulge. its a nice little bag liner nothing much more. If your a minimalist I say go without it. This is strictly a comfort item for me, Ill probably carry it for that reason, but I do Roll pretty heavy and tend to bulk up on the comfort items a wee bit more than some backpackers.

Not As Good As I Thought

Used it on a two night backpack in the Sierras in October and the temps dropped down into the low twenties and high teens. I have a rectangular down bag and the Travel Sheet definitely added warmth to my bag. The material felt nice and soft and cozy. Unfortunately, I found it very difficult to get in and out of in the middle of the night because it is so light and thin that it would twist inside the bag and stick to me and pull out as I was getting out of the bag. I then had to reorganize it to get back into the bag. It might be great if used by itself or in a bed, but I am not sure if the difficulty and inconvenience is worth the extra warmth in a sleeping bag. I plan a two week hike and I would not want to deal with it for that long. I do want to keep my bag clean, so maybe a liner of different or thicker material might be easier inside a bag? I love R.E.I. because their great return policy, and I will probably take it back and try a thicker fleece or cotton/silk liner.
Wheeler Ted at REI on 10/10/2013

This thing is ok i guess, but its pretty thin. It is like a cross between a set of jersey knit sheets and a pair of nylons. I wanted it for staying in hostels, but i didn't think mesh was going to keep much dirt out, so i returned it and bought a silk one. Bottom line, too thin.
