I have tried out hundreds of pairs during my work as an outdoor instructor, none keep my hands dry after prolonged use.
Dachsteins are great
Showa cold gloves these look a bit weird but do work
Showa Thermo grip gloves fantastic grip and warmish
or these http://www.toolbank.com/p/D4791/SCA/SCAGLOKSTHER
or this which i bought a pair of in Chamonix and are fantastic and cheap but could only find this Hungarian site
Silk Liner Gloves
what do you use? these are great alternatives to the branded expensive gloves that we tend to buy and use.
