Perfect, compact, portable, comfort.
Color: Grey, Size: Small
Got the small one. It's perfect size for camping. I saw other comments with pics of medium and looked too big for portable use. I like down feather pillows and this one is really close to same feel. I recommend it 100%. And I may even buy another one.

I really wanted to like this pillow but I didn't, My son did.
Color: Blue, Size: Medium
I bought two of these Medium pillows for summer camp that my son and I went to this year. Let me start by saying the only reason I don't like it is because its too soft and small for me. By soft I mean the pillow bottoms out when I put my head on it. I measured and it is 4" thick but when I put my head on it, it almost disappears. They could add 20-25% more stuffing and it would be great. My son liked his, I didn't even bring mine. What I did do is stuff a standard size memory foam pillow in the stuff sack and used that! The quality of this pillow is great, the seams were not torn or coming undone like some people said, no rips or stains. the zippier works just fine and IT IS MEMORY FOAM, people who complain that it's not are expecting a brick of foam which this isn't, it is shredded/torn memory foam filling that is exactly like my $60 memory foam pillows that I use on my bed. TLDR its great for kids, not for people with bowling balls for heads like me. WISE OWL, ADD MORE FILLING ! I was able to stuff a pillow 3x the size of this one in the same bag.

Comfy!
Color: Black, Size: Medium
It's very comfortable. It's a good size and thickness. I wish it had a strap to hold it on to your air mattress or cot. Good value!
