I bought an ENO pillow last fall at a little "Mom & Pop" outdoors store in Guntersville, AL. Yeah, they're expensive but I was trying to help out a locally owned small business.
All in all it's a pretty good pillow I think, if for no other reason that hanging it by the compression strap from my ridge/suspension line (I use a SLS) puts it at the perfect (for me) height for it to go under my head with the added bonus of not being able to fall to the ground.
After several Saturday naps I've decided that I like this pillow better than my Thermarest for hammock use.
Anyone else have any experience, comments, etc?
