Geier Gloves Co. out of Washington. When I first discovered these gloves I figured they were probably the OEM for Filson. On a plus note these Geiers gloves are way cheaper than the Filson ones and the sizing is much more varied for a better fit.
The lining is merino wool so its warm and soft to the touch. It's also not too bulky so working the back trigger on double trigger shotgun is not a problem. Since all the shotguns I hunt with use this set up, its perfect for me. When ordering a lined glove make sure you order at least a half or full size bigger than your unlined glove. Geier does not adjust for the bulk of the lining when it comes to sizing. In other words if you are a size 9 (like me) the lined glove will have the same dimensions as the unlined. The extra bulk of the lining will make it a tighter fit so it will require you to go size up. I ordered a 9.5 for the lined gloves and it seems to be a perfect fit.
These came just in time as the old man and I plan on hitting the valley again in search of waterfowl. With a little bit of luck we'll be coming home with some good tasting birds.
