Tested this in the shower to simulate HEAVY RAIN. This product failed to keep me dry. With the use of the hood, the hood compartment opened, it catches water and drains the water through the hood tightening band's grommets, releasing water over the chest area and anything below.

Flawed. Do not stake your life on this jacket when trekking the great outdoors. But I suppose if it wasn't going to be the fatal flaw that is pointed out, it would have to be the unsealed zippers and the velcro wrist adjustment is 2 or more inches too short (the fuzzy side of velcro). The circumference for the wrist opening is HUGE it is about 12 inches. 12 INCHES!!! I bought a medium size!

Consider this returned upon reading. You have been warned.
