In reply to Tricadam:
Thanks for the advice folks. I tried some of the liquid Nikwax Waterproofing Wax for Leather on my older pair of G2 Alpines and it looks to have rejuvenated them very nicely.
Dave, I'll have to try those Simond ones. If they do fit folk with long but not overly wide hands, that should be about right. I too tried the famed Argon gloves but find that on me the fit is terrible so they've been relegated to de-icing the car use!
