I live in central Maryland and we had about 4" of snow overnight, so I had to shovel the driveway and sidewalks. Decided to try out the new gloves I bought last month - Seirus Windstopper/Weatherstopper. Within 10 minutes my fingers were not just cold, they were hideously painfully cold. I hadn't touched any snow, just the wood handle of the shovel. I got them off and found my old OR Windstoppers and put them on. Took about 3 minutes for my fingers to thaw and get snug and warm. I spent another HOUR our there shoveling and my fingers were quite comfy. The Seirus are going back to REI tomorrow. $45 to have my fingers nearly die - I don't think so.
Should add, it's also quite windy out there and the new gloves did nothing to stop the effects of that. "Windstopper" indeed.
