As comfortable as my pillow at home
This is one of the best purchases I have made since getting into backpacking. This is the only "luxury" item I bring along, and at 7 ounces for a small it is worth every gram! This pillow deserves 6 stars out of 5. The small is more than big enough for me, and provides enough room to move around. The loft should be high enough for most side sleepers, but if it is not you could fold it over. Since receiving this pillow, I have slept on it every night at home, as well as nights outside. It is every bit as comfortable as my normal pillow that I use at home, and actually lofts up higher than my "home pillow"! It was (as you would expect) very flat when I first uncompressed it, but after kneading it a bit and letting it sit out for 30 minutes it fluffed right up. I couldn't be more pleased with this pillow. At 7oz it is pretty heavy considering the other options available (stuff sack with jacket inside, inflatable pillow), but the extra comfort is well worth the weight. This is my first time reviewing a product here. I was just so impressed by how comfortable this pillow is that I wanted to come and say so. You won't be disappointed if you buy this pillow.

A must for side sleepers!
Make sure to wash it according to the instructions before first use. Dry with LOW LOW heat (Took my dryer about 3 hours). Packs down about 25-33% of its full size when compressed.

Makes all the difference
I have never been able to sleep very well camping and this pillow has made all the difference. It is comfortable, compresses well and uncompresses well especially if you wash and dry it once before use. Get this pillow

Love it!
I ordered my pillow just in time for a trip to Ramsey's Draft Wilderness in the GW National Forest in Virginia the weekend after Thanksgiving. The pillow was great and made the 25 degree F temperature the first night more tolerable. In the past, I would sleep with my pack under my head, but the Thermarest pillow is a much more comfortable alternative. It is lightweight and compresses down to about the size of a foot long Subway sandwich. I have read some reviews that complain of the pillow not "uncompressing" well. I did find this to be a problem. Just remember to fluff the pillow according to the included directions. I highly recommend this pillow to add comfort to your back country experience.

Great Compressible pillow
If you like a full sized pillow when sleeping under the stars, this pillow is it. Just give it time to un-compress.
