After trying to find a neck pillow for travel and many returns, I purchased this pillow. I love it! I have a long and thin neck and all the neck pillows did not provide enough support and constantly rotating the neck pillow does not work for me. Switching to this pillow was my answer. It came compressed and I followed the instructions (15 min in the dryer on low with a couple of dryer sheets). The pillow fluffed right up and is super comfortable and supportive. There is no smell. The cover is very soft (a must!). It easily compresses into the provided bag so easy to travel with. It's also the perfect size, small enough to easily travel with, and large enough to provide support. I recommend it.

Soft, Comfortable, and Great for Camping

Color: Grey, Size: L-23 X 16 Inch

I bought this travel pillow for my son’s first camping trip, and I was really impressed. It’s incredibly soft, nice and fluffy, and made a big difference in keeping him comfortable overnight. It was such a hit that I think his dad was a little jealous I didn’t get him one too! It also packed up easily and fit back into its bag without a struggle, which is a huge plus when you’re camping. It held up well during the trip and did exactly what we needed it to do. My only criticism is that it’s a little pricey for what it is. That said, once you feel the quality and comfort, you can understand why. Overall, I would definitely recommend it.

Comfy and practical

Color: Grey, Size: S-16 X 12 Inch

The best travel pillow for anyone looking for an actual pillow and not just neck support. We have used it on several trips both on a plane and in the car and it is great for both!

Used for the very first time over the weekend - was more than comfortable and compact enough to fit into my multi-day teton pack..
