User Review: Cocoon Air-Core Ultralight
Source: bought via a "pro deal"
Price Paid: Can't say. It's $19.50 retail.
It's light. It's bouncy. It slides across the tent floor.
When I saw this I thought that it'd be a great solution. I tried it in the store for a moment and it seemed fine. It was a different story in a tent.
The pillow weighs a little less than 4 ounces, has one side that's microfiber (nice) and the other that's coated ripstop nylon. The nylon side doesn't feel so good against the skin. It's sticky and hot. When you put the nylon side down it slides off sleeping pads and across the tent floor every time you roll over. I put it inside a T-shirt and it slides around inside the T-shirt.
This may just be me, but I don't like the rounded and bouncy character of the thing. My head has to be centered exactly or it's not comfortable, and as I mentioned it will go flying across the tent. Also, after lots of inflations the pillow will have more and more moisture inside from my lungs. It will weigh more and be less insulating.
I work at REI so I very much hesitate to return items so I'm sort of stuck with this pillow, but I won't use it. It's retired. A far better option for me is the 4-ounce REI Travel Pillow, and it costs $5 less. It stays in place, feels ok against the skin, self-inflates, and doesn't have that rounded and bouncy feel. My REI doesn't usually have these in camping. Instead they're in travel.
