If you fish anymore then once a summer, then there is no use in buying anything other then simms waders. They have many different price ranges and styles to fit most budgets and tastes.
I have worn them all over the years and nothing holds up like Simms, and if they do have a problem, they will take care of them for you. I just retired a pair of Simms gore-tex waders which had their 10 year mark passed, those who know me, know they spent a day or 1000 on the water.
Take it for what it's worth, but the rest suck in comparison. Cloudveil, Orvis, Hodgman, Cabelas, all of them are not worth a wooden nickel.
