If you want a reliable and non-noisy, warm pad, this is it. All pads are prone to some leakage of air over time, so Exped always provides seam patching kits - I haven't "yet" had to use it... although I'm sure I will ultimately. I'm 5'9+, but as a prone stomach sleeper I need a long and wide (LW). The pad feels great.
