I should add a little background to my earlier post, I have made my living shooting ski photos full time for the past 25 years for the likes of Nat Geo, Powder Magazine, ESPN, and Ikon Pass and others. So I know a thing or two about winter "work" gloves. If you are doing hard work, I.E. shoveling snow, tying ropes, etc, Kinco's are the way to go they hold up well and they are cheap enough to have multiple pairs. The key is to seal them with Snow-Seal, which is basically a fancy wax, and that works best if you toss them in the oven (best if your wife isn't home) on low for 15 min to bake the wax in.
Personally I use the
BD Guide Gloves. They hold up well, are very warm and work great even with "wet" snow.
If you live in a cold climate with low humidity, I.E. Colorado, then Hestra is a great option.
At the end of the day the key to good gloves is to pick a set that is appropriate to what you are doing. I.E. heavily insulted gloves when you are working hard at 30F is going to get soaked from the inside out do to sweat. Just like you are going to freeze in a pair of super thin gloves at -30.
Also, the "DWR" coating on the fabric is more important than the degree of waterproofness. This is what causes the water to bead up on the fabric and not soak in. No matter how good the goretex (or knock off is) once the outer fabric is soaked, it no longer breathes and you will get drenched from your own sweat. The DWR coating can be refreshed by tossing it in the dryer on high heat.
Finally do NOT use any of that scotch guard or wash in nikwax ****, etc. That stuff waterproofs both the inside and outside making it all useless. If you really insist on using that ****, its best to buy the spray on stuff so its only on the outer shell.
