Sitka vs. chene. I own and wear both regularly, probably more time in Sitka just because I’ve had them longer. I work in wetlands, guide duck hunts, and trap and hunt myself. Probably over 100 days a year in waders.
Material - as far as I can tell they are made of the exact same material. It’s durable and lightweight - similar but thicker than cheap breathable waders like cabelas.
Boots - Sitka has a lacrosse boot, super comfortable. Chene has a similar boot, I don’t know who makes it but it is similar to lacrosse, bogs, muck etc. Also very comfortable. If you are undecided on size order up as I think both brands run a little small.
Straps - both use the same front hook system which was strange at first but really works well. The chenes have some added neoprene padding on the shoulder harness which is nice but it’s not like the Sitkas are uncomfortable.
Fit and finish - I’m 6’ 185 and the sitkas fit like a glove, very comfortably. The chenes are also super comfortable but ride up in the crotch a little and are slightly taller overall. The sitkas have a bent knee, similar to a performance hiking pant, while the chenes are straight leg. I don’t think it makes much difference in fit. I suppose that makes more seams in the Sitka leg if that concerns you. The zippered front on both is awesome. I think the zipper on the sitkas goes a little lower.
Layout - nearly identical pocket layout. The zipper front on both does mean you loose the single big pocket most waders have, but I don’t miss it now. I think the Chene has a smaller inner pocket and the Sitka doesn’t, but I’m going by memory on that. Sitkas belt is a little nicer. Sitkas also have built in knee/skin pads which is actually a really nice touch but again - more seams. The chenes also have a cuff over the boot which traps mud but protects the neoprene boot sides. I’m undecided on that, might be nice in timber but so would boot without soft neoprene sides.
Warranty - I think both are similar. I have sent clients waders in to Sitka for warranty work and it was fast and a great experience. Never used it myself or chenes. Most of the sitkas I sent back were for punctures, but one did develop a pinhole somewhere near the leg/boot seam.
Overall I’d give the edge to Sitka, especially because the price is slightly less.
I’d be happy to post pics or answer questions about Sitka, Chene, high n dry, cabelas dry plus, orvis, or USIA waders if someone has specific questions. I have no experience with Simms but from what I’ve read I hold them in high regard.
