I have the small and I love it. You definitely have to give it a good beating to get it fluffed up. Of course my camp mates roll their eyes but they are secretly jealous...

The Thermarest Pack Pillow has been fantastic on many of my trips where I find myself lacking a suitable pillow.

Operating instructions:
Just loosen up, beat the crap out of it, and wait 15 minutes before crashing for optimal fluffage. Medium is my optimal size (strictly carry-on bags/size+weight ratio), your mileage may vary.

Maintenance + care:
When you're not too busy beating it, just be sure to wash it every now and then. Please be considerate of your pillow's feelings and use a front-loading washer if possible. Fluffageability remains constant even after frequent purgings.

I admit it, I'm a pillow snob. Off the trail I employ a super-firm memory foam Cadillac-Class pillow. Most commercial pillows are too soft for my taste, and feather pillows are just plain uncomfortable. I was skeptical of any trail pillow, but there had to be some improvement available to best my rolled up fleece in a stuff sack.

Oh baby, come to daddy! This pillow honors the therm-a-rest brand with a head cradling solution that weighs nearly nothing, rolls up small, yet demands little compromise in comfort to a standard pillow. Give it a little fluffing after unrolling, and let it sit a while to poof up to full loft. Come crash time, it'll be ready to rest your tired head. Like my therm-a-rest pad, I find it best to store the pillow unrolled when not in use to shorten 'poof time.' It's probably better for the fill too. Give it a try goldilocks, you'll be glad you did!

A better night's sleep while camping means more energy for the next day's adventures. Headache sufferers (myself included) who need to "sleep it off" will find this pillow a great relief. Tried many "camp" pillows, and this one wins my vote for the most comfortable, with the least amount (none so far) of neck stiffness or pain in the morning.

It weighs more than the inflatable types, but a good night's sleep is well worth it to me. I started with a large, at 12.3 oz, and have just purchased a small, 7.2 oz, to shave off some extra weight without loosing the comfort.

For those concerned about how much room they take up in a pack, the small size compacts down to 10"x4"x3.5" when rolled into itself, while the large size compacts down to 13"x5"x4".

At first, I was thinking, eh, this isn't the best, it's lumpy and uncomfortable, and it makes weird rustling sounds in my ears from the form compressing/decompressing--then I used it a couple more times. Now, I'm really into it. Seriously, I have no problem trading out my bed pillow for this pillow. I think the first night I was just thinking too much about the pillow--it was a "princess and the pea" situation.

I recommend the large. The pillows really don't take up all that much room regardless of size--I squish mine down smaller in a compression sack. The foam really compresses very well. I own the medium and the large and I like the large better (I'm a side/stomach sleeper). The large has more foam and provides better support. I don't think the medium compresses all that much smaller and comfort benefit of the large is very worth it. Note: if you're using it INSIDE the hood of a mummy bag you may have different preferences--I camp in pretty warm climates...

If you're going to pack in a pillow, this is a good one. Remains firm & comfortable throughout the night . Compresses tightly & packs in my sleeping bag stuff sack. My medium weighs a slightly heavy 9oz. Invest in a good night's sleep.

The title says it all. This Pillow is Awesome.
I used this pillow for a week of tent camping and it was awesome. I can't believe how nice it compacts and then it fluffs up in a matter of minutes. This pillow kept its firmness all night long. It is well worth the money.

I've tried a number of other types of camping pillows and this one is the best. When you first look at it, it doesn't seem to have much loft. You just have to puff it up for a minute then let it sit a bit and it gets super puffy. Great for car camping and compresses small enough to use for backpacking if space isn't too tight.

After seeing the condition of some of the hotel pillows in Africa, I decided to pick up one of these. It has become one of my favorite travel companions.

When you first get your TRCP you'll notice its compressed into shape as you would as if you were gonna pack it .... Its stored and shipped this way, so you must expand the pillow and fluff and allow 15-30 minutes for it to fully refluff ... Even on the tag is displays this, as well as cleaning instructions ... The pillow holds loft amazingly over night and is so soft you'll be asleep before you find a fault to it ... A good 3 1/2 to 4" loft ... I got the 12oz large ... my pillow is my number one priorty for sleeping ... You can't go wrong with this pillow, medium or large.

For ages when camping with my gf I would use her as a pillow. She was warm and soft. She was never comfortable though, maybe I have a big head.

So I buy this awesome pillow (in large, for my big head) and its oh so comfy. I also bought a warm sleeping pad.

Now I no longer force her into a snuggle in order to keep from freezing, I am quite content on the other side of the tent snuggled into my own little ball.

However, I can hear her gazing at me with evil eyes with crossed arms contemplating various methods of exterminating me throughout the night. So even though this pillow is super comfy I now can't get a wink of sleep for fear of being slaughtered dare I catch some shuteye. It's a real mess.

My wife rolls her eyes at most of my purchases, only to find them useful, comfortable or convenient later on. This is no exception. I'm a pillow guy, if the pillow sucks, a restless night is sure to follow. This pillow gave me a very restful night sleep. It may be a little bulky for some, but it doesn't weigh much would be able to squeeze most anywhere in/on your pack. If your going camping with a significant other, be nice and get them one too.

I'm not sure if I just got a bad one or not. I tried the medium size and it fluffed out nice. But, I also got a large one and it refused to fluff out. I did everything I could think of to make it fluff out but it just wouldn't do it. I finally gave up and sent it back. It was so deflated that it looked like they tried to put the same amount of fluffing from a medium into a large size. I finally bought a Lafuma big bear polar pillow instead. It is rather large, but I have a bad neck and need a comfortable pillow. So you may get one that fluffs out nice and you may not. Be sure to test it out before you go camping.

In answer to someone's question, you don't need a sack to put it in. It folds up into a pouch sewn into the pillow.

This is a little heavy, but to me it's worth it. I can live with 9 extra ounces for the comfort this brings. I got the medium which is 18" wide, so it works great with my 20" wide pad. It compresses to about a fourth of its fully lofted size, and really is way more comfortable than balled up clothes.

I have the medium and have brought it all over the country. From 3 straight day road trips to multiple week camping trips. This pillow rules. It's actually amazingly comfortably and packs pretty small considering it's girth when unpacked. It's definately worth bringing if there is even a tiny amount of room to spare. I absolutely recommend this product.

I agree that a pillow in the back country is a luxury; but having had a neck injury from a bad fall in my past, I found my self continuously using boots, fuel bottles wrapped in my polar fleece, or anything else I could fanagle to get a good neutral plane for my neck alignment in order to get enough rest and to not wake up with a headache. The thermarest has really helped. Nice and light. Good compression. For me, it is a must in order to stay out longer and feel better doing it.

I was a little nervous when i first got this since it seemed like a half filled pillow with some foam pieces in it. When I went back to the tent later the medium pillow was totally full and puffy. It provided great support and packs really small for how big it gets. Open it when you get to camp so it has time to "inflate" in true therm-a-rest fashion.

This pillow is amazing. It's hard to believe it fluffs up just like a regular pillow and keeps it's firmness. We have used it about 4 times now and it still has kept it's shape.

Having a pillow while camping is definitely a luxury. I thought the pillow would be a little bigger... but after trying it worked well!

Compresses well, expands quick once you unroll it, and lightweight. Nice luxury item to carry if you have the space... better than trying to use your stinky clothes as a pillow.

I used this on my trek through Central America. Its probably the nicest camper pillow I've ever owned. It stuffs down to a small size, but open it up, give a few minutes to expand, and it works great! It definitely supports my achy neck better than any other camper pillow I've purchased.

Worth the extra weight, and downright civilized!

Sweet little pillow. The small is a little small, but that's all that was in stock when I ordered mine. Still worth it. Comfy pillow. Just let it fluff up and you're good to go.

This pillow is amazingly firm once it fluffs up, it is infinitely more comfortable than sleeping on a rolled up jacket, and it packs small. This is one of those pieces of gear that, once you use, you will never want to camp without.

This is a really nice pillow. I make room for it on all my backpacking trips. And great for cars and planes too.

fluffy and compact, Helluva lot nicer than using my boots.... i got the small, if (when) I get another it will be this pillow, just a larger size.

I needed a pillow for a motorcycle trip and decided on the medium size. It was super comfy - just let it expand for @ 20 minutes before sleeping on it. Once it's been expanded once it doesn't squish down as small as when you initially recieved it, but it still compacts fairly well.

I LOVED this pillow! Great addition to my camping gear. Slept like a baby every night without the uncomfortable neck pain I usually have. Packs up small, fluffs out nicely. Awesome!

This is the best backpacking pillow I have tried - and I have tried a bunch. This pillow seems to be filled with crumbled-up Therm-a-Rest foam, so it fluffs itself up after you unroll it. I still put a rolled-up jacket under it to get the right height, but the pillow keeps its shape and stays fabulously comfortable all night long, all week long. Worth the money, the weight, and the space.

A must have! Easy to wash, easy to pack, wonderful companion for long trips. I even used it as my regular pillow when I was in Nepal and India... The medium size is perfect.

Not like the pillow in your bed but certainly a luxury. I camp from my motorcycle so its plenty small enough and beats the heck out of waking up with a sore neck.

I am so glad I found this for camping. I got the medium and it fits perfectly in my Big Agnes sleeping bags pillow pocket. Very comfy and packs pretty small as well. I almost want to get a large to use as my everyday pillow.

The Therm-a-Rest Compressible Pillow is a great addition to my backpacking gear, and a good substitute for my bed pillow. I ordered the small, and at 7oz, it is very comfortable. Your head doesn't sink too far like you might find with the Western Mountaineering pillow, but you are still able to enjoy the soft-feel of a normal pillow.

The pillow packs well and doesn't take up much room in my pack. I use to use the Therm-a-Rest Stuff Sack Pillow, and while I still like that feature of the stuff sack/pillow in one, it didn't do me justice from a comfort perspective. What can I say, I think that a great pillow is key to a good night sleep in the backcountry.
