Not surprisingly, there are as many recommendations as there are brands and types. Here's my ten cents worth gleaned from 50 years of British weather. Overmitts will keep you usual gloves dry-ish (nothing to prevent the trickle down from the jacket cuff) but can be slippery and worryingly unwieldy when you want to hit the brake. Synthetic gloves of all types, from household to motorcycle, tend to be more waterproof but offer little protection unlees they are armoured which is uncommon. Interlinings like Goretex are pretty effective but often leak at the seams or where there is pressure like ends of fingers and thumbs. They also leave you with saturated leather which can feel cold if not wet. Price IS NOT a determining factor. I have had great results from a bargain line and total failure from very well known brands. Good luck to those who return brand name leaking gloves to the retailer. The best case scenario is that you will have no gloves for an extended period while the manufacturer "examines" them and decided what action to take. The worst case is you are wasting your time. Best tips whatever you choose...... Tuck the gloves inside the cuff of your jacket. It is the only way to prevent water trickling down into the gloves and very little water will get blown up the cuffs if they are snug. Get heated grips. If your hands aren't cold, being wet isn't too bad. On the S10, consider the kind of extended handguard tops supplied by Touratech. They work like an onboard overmitt. Finally, against all logic, you chose to ride a motorcycle in the rain ... what did you expect?
