ive noticed my so called waterproof textile gloves get sodden now even with wiping water just off the seat need a new pair soon as the lining comes out too :'(
Gerbins looks interesting. I have had serious problems with my fingertips last winter - that's with a fairly thick but cheapish Buffallo textile glove and coldkillers liner - I used to run into work in absolute agony and hold my hand under hot water to get some feeling back and to kill the stinging and burning sensation.
I think I will try those Gerbins this year. For waterproofing, if you are stuck, just wear a larger size thin latex gloves over your good gloves - sure it wouldn't be breathable, but it surely will be waterproof!!
Brush guards, heated grips, spada enforcer winter gloves, (or now Triumph waterproof gloves - not as warm but ok) and heated jacket liner keep me going all winter.
Not tried heated gloves though.
I've still got a pair of leather mits (wool lined) which I've had since my early days of riding in the mid 60s. Much warmer than gloves, even when water leaks through in really bad weather.
