Received the Kelty Kenosha pad today. It comes rolled up and secured with two elastic bands. I unrolled it, and loosened the valve to let air in, but the pad is not self-inflating. It just stays flat and wrinkled! I have tested a similar self inflating pad at Costco, and the one at Costco self inflated very quickly. This Kelty is literally doing nothing. I hope the problem comes from being rolled up in storage for a long time? The pad has been at room temperature for over an hour. I'll leave it open to see if it gets any better, but if it won't inflate, I'm sending it back!
