I've got a set of the OR's and a set of kuiu right now.

I got my kuiu when they first came out 3 years ago and I blew a buckle on the strap that goes under the boot the third day I wore them. I fixed them with a brass rivet a week or so later after I finished the hunt and they have been going strong since.

My first set of OR's lasted me two season of guiding in the Yukon wearing them every day from mid July to mid oct, climbing mountains and riding through willows.
