My friend works for an Orvis store, he got the ultralight waders when they first came out. First day on the water with them and they were leaking. Think he sent them in, got another brand new pair and those leaked too.
I've had the Orvis Silver Sonic Convertable Top Waders for about 2 and a half years now and haven't had a single issue or complaint. They've been through hell and half - briar patches and thickets, crawling around on boulders in the Shenandoah mountains, and have been on multiple trips in a variety of conditions and I think I may now have a small pin hole in one of the feet (still trying to figure out if its sweat or water...). They aren't the best in super hot weather - which is when I wet wade anyways. They pack up pretty small as well - I've traveled with them in luggage multiple times. Also bought the access wading boots with those waders and can't complain either. Only had to replace the laces and can't even remotely notice any sort of damage /split seams, etc. on them yet. They are tanks and definitely lean towards the clunky wading boot side of the spectrum.
