I bought a pair while on a drive up to Ely for a snow carving event. I usually wear one pair of gloves a day during these events because I sweat through every fiber. These mitts, though, lasted the entire week. I swapped in a fresh wool liner every day, but the canvas shell was reliably dry.
After 40 hours of heavy activity, I started to see some wear on the leather and I rubbed off all of the wax. This was likely because the fit is a bit loose in the fingers, which makes gripping tools a bit challenging (they run big). To be fair, these weren't marketed for the use I put them through, but I will for sure buy a second pair when I eventually wear these out.
