I work outside allday for a Railroad. Very durable and withstands the most extreme downpours. I recommend them for anyone
It’s as rugged and technical as storm protection comes. We built Stormwall Rain Bibs to defend against driving rain and slashing branches alike thanks to triple-layer fabric technology. The shell is rugged, ripstop nylon that shrugs off scrapes, with a comfortable lining inside that keeps it from feeling clammy like common rainsuits. Sandwiched between those layers? A high-performance 15K waterproof, 15K breathable barrier that keeps you dry and comfortable even when working up a sweat. The leg zips come to the thighs, which makes them easy to pull on over bulky rain boots. Gaiters at the cuffs shut out water even if you step in a stray puddle. Sometimes plans demand you get out there whether it’s rain or even more rain, but put on a Stormwall and you’ll stay dry through anything.

I've only been using these for a couple weeks now, but in these couple weeks they have seen as harsh conditions as some may in a much longer time. I work in a fish hatchery/retail business.They have been exposed to very wet conditions for more than one 12 hour day. I have seen rain/sleet/snow, and have stayed dry. They are comfortable and fit true to size. As for durability, time will tell, but they seem to be up for the test.
