I have a pair of gloves that I really like. The only problem is that they weren't water repellent. As a matter of fact they soaked up water like a sponge. I tried several different silicone based products with no success. Than I ran across this stuff at WalMart in the shoe department.
It's Camp Dry Performance Fabric Protector by KIWI. According to the can it's a polymer. It works great. Two warnings:
1. Make sure you get the Camp Dry Fabric Protector, not the Camp Dry Heavy Duty Water Repellent.
2. DO NOT USE IT INDOORS!! The fumes are intense.
It says you can even use it on suede and Gore-Tex.
