This is the first I've seen them mentioned but they have my interest piqued. My Sitkas made it six seasons before they started leaking and they are without a doubt the best wader I've ever worn. Nothing even comes close. I am sending them off for new boots. But, I was told they have changed boots, and not for the better, and this concerns me as everyone knows the boot makes or breaks a wader. The KUIU boot looks outstanding. I wish they had foam in the knees like Sitkas because boat hunting means a lot of knee contact, especially in a Devlin. That is a feature I don't want to lose. I think I am going to call Sitka and enquire about their new boot. If they have gone away from a neoprene based insulated boot and are using some thinsulate like crap I will be in the market for a new wader brand. This wouldn't be the first time a company made an awesome product and then cost engineered themselves out of the very features that made them the best on the market.
