Tough like nothing else
I sized these up so I could use them with a fleece liner for ice climbing belays. Basically, I'm tired of trashing my good gloves in only a few days. They've seen a season of iced-up ropes (which bare a striking resemblance to barbed wire) and they still look great. I can't imagine wearing out a pair of these in less than 5 seasons of regular rock belays.
