I must of got a lemon for pronghorns, I've been very happy with them the last 3 seasons and they've never sprung a leak. It did take a little while to break them in. I'd imagine I've had more time in the woods this fall than the mass majority of people commenting on this thread and they've held up just fine. I got a new pair of uninsulated ones for Christmas that are very comfy right out of the box.
