I've had a Simms Pro Dry jacket and bibs for 6 years. Still going strong, like new...don't leak a drop, even running down the lake at 40mph in a rainstorm. Water rolls off of them in droplets. Well designed cuffs and collar/hood to keep any leaks out. Very breathable too, never sweat in them. Best rain gear I've ever owned.
Most of the time they're stored scrunched up in one of the in-floor compartments of my boat. All I do is, twice a year or so, wash them with NikWax Tech Wash, then tumble dry on low to maintain the DWR. The fabric is GoreTex 3-Layer Pro...as far as I know, there's nothing better out there.
