I ordered both the petite and regular and the air valves were totally different on them. The regular has a very sturdy looking valve with BA written on it. The petite's valve was about 1/2 the size and no BA. I don't know if it was a replacement valve or what. I inflated both, double checked that the valves were tight and let them sit overnight. In the morning, the regular was plump and full and the petite still had a good amount of air but was soft when squeezed. I returned the petite and ordered another regular. I have used a borrowed BA sleeping pad before for a month of hiking and it was awesome. Looking forward to using the regular pads and trusting that they will stand the test of time.
