very comfortable
Yes , I recommend this product
As soon as it arrived I opened it up and tested its self inflate feature and after a few hours, they only recommended waiting 30 mins, it hadn’t inflated at all and yes I opened the valve and gave it a couple of breaths. I then blew it by myself which was very quick with only 10-15 breaths and sleep on it that night and it was very comfortable. I live REI gear and I’m sure it will do well for many nights to come but the self inflating feature just didn’t work which is cool because I grew up blowing them up manually so whatever. It just would have been a cool feature.

Comfortable but does not self-inflate
Yes , I recommend this product
This sleeping pad is very comfortable and not too heavy/bulky, which is what I was looking for a first-time backpacking trip, and not too excessive with respect to price. It is, however, difficult to roll-up and fit back into its original packaging and does NOT self-inflate (I waited 48 hours). I needed to purchase REI's sleeping pad pump, as I would have likely passed out trying to inflate it with my breath.

No, I do not recommend this product
This is pretty comfortable, but it does not self inflate and is very bulky. I wouldn’t recommend this backpacking but would for car camping
