Dru- I climb w/ the 2001 (?) model of the Mixed master as my belay gloves. This was when they made the waterproof layer part of the fleece glove. These gloves are pretty damn thick and the new version I saw at MEC this summer (which has a gore-tex shell now) is even thicker and more expensive. I tend to pump out even following in these gloves because of their thickness, but if it's cold out..
They sure are durable though, I seam sealed the seams and nixwaxed the palms and they've been taking rappels, belays and screws for two seasons now. look almost like new too.
I also tried the MEC "Glacier glove" this year, which is a BD Dry-tool looking glove made with Powershield (I think). Not bad for a thin leading glove at $32 CDN, but the leather on the palm/fingers is SO thin that it started tearing off the finger tips on the first use. IF they put a little thicker leather on these they'd be sweet gloves..
Also, the Vinylove gloves are rubber with a synthetic lining, not neoprene... sort of like alaskan grade dishwashers gloves.
Dave, now that the liner is in the glove, not the insert, the glove is about 1/3 THINNER, not thicker as you wrongly suggest. Wow still on 2001's huh. Must be the seam sealer and Nikwax.
The only prob i have had with mine is gloved finger getting in the corner of the picture when taking pictures with the gloves on.
Maybe yours are sized too big?
