Hubby purchased these shorts/pants for climbing/hiking, but asked if I could do anything about the fact that there is no mesh "pocket bag" when you put a phone in the velcro flapped back pockets.  There is just 1 layer of mesh attached to the pant rather than a 'bag' with 2 layers of mesh like there are on the front pockets.

Is this pair just an anomoly, or am I missing something on the function of Convertible Pants?
