There's nothing quite like the feeling of watching the water just bead up, and feeling the extra weight all over you, all while remaining perfectly dry. You need to be conscientious of you fellow adventurers, though. In a good downpour, just a twist, or a jump, and a spray of water launches from the jacket. Its fun to see, but you dont want to soak your neighbor.
The design of the hood is very functional, and adjustable to help with changing conditions. The breatheability is awesome; you never feel like you have a garbage bag on, and you can regulate the heat very easily with the pit-zips. The jacket is relatively wind-resistant
although the gale at the top of the mountain will point out to you that it is not wind-proof.
This is no heavy weight, nor is it the all weather gear (it can stick to your skin), but for the "just-in-case", or the extra shell on top, it fits the bill perfectly.
