Rated 5 out of 5 by from 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!

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from Brazil Best Item This was a Lifesaver! My son & 2 of his friends went to Brazil for 2 weeks to attend the World Cup. I did some research, as they would be staying in Hostels, and a travel sheet was recommended. Since it was last minute & I had no idea what this item was, I searched for it on REI & ran over to the Northridge store to check it out. The guy was so helpful & recommended the CoolMax ones due to the humidity factor. One night they were staying at a hotel, so they thought they did not need to use them, WRONG! They all got bit in the night so they used them the rest of the trip & no more bites. I washed them in hot water & put them in a hot dryer at the laundromat & they came out in perfect shape. THANKS REI!

Rated 4 out of 5 by from 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.

Rated 5 out of 5 by from Great for travel! I am an airplane pilot and use the travel sheet in our crew rest area in the airplane. The standard size airplane blankets are often very small and not very useful. The travel sheet is like a ultra compact sleeping bag that fits in my flight bag. It provides just the right amount of insulation and eliminates any exposure to drafts that be present. Additionally, I have used the travel sheet when stuck at the airport and need to spend the night on a sofa of rest seat. I would recommend this for flight crews or frequent flyers!

Rated 3 out of 5 by from 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.

Rated 4 out of 5 by from 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.

Rated 5 out of 5 by from One of my favorite possessions I have owned and used this item for more than two years and it is one of my favorite possessions. I travel quite a bit internationally and this thin barrier between me and whatever pillow and sheets are provided by guest houses allows me to sleep peacefully. I highly recommend for budget travel in Africa and warmer parts of Asia, particularly if you are squeamish to questionable bedding. The material is relatively cool, and easy to wash and stuff for the next trip. The moment this tears, I will buy another but it is perfectly intact so far, making it more than worth the price.

Questions & Answers

I've lost the stuff sack for this. Is a replacement available, or can you recommend a suitable replacement? Thanks-

Asked by: Mule
​A good replacement for the stuff sack is the 2.5 liter Ultra-Sil Stuff Sack.

What is the pore size of the fabric (in microns)? Will this protect against bedbug bites? And given no zipper, the only opening is at the top?

Asked by: jeanm
We're sorry, but that information regarding the pore size is not available. The only opening to the travel sheet is at the top. This sheet is not designed to protect against bed bugs.

How does this do with the condensation in a bivy? Does it keep off the chill? I'm thinking 60F to 75F degrees, when my quilt is too warm in the bivy.

Asked by: Jbeegoode
The Travel Sheet is made of moisture wicking material so it does pull moisture away from the body to eliminate chill. It is not given a temperature rating as a warm weather sleeping bag. The comfort rating will depend on the individual.
