Cabela's GORE-TEX INFINIUM WINDSTOPPER Handmuff
Any one who has bow hunted in the cold knows that keeping your shooting hand warm is a challenge. I wear a very lightweight glove on my right hand, so I can use my release. I can get away with a lightweight glove (or no glove) by using Cabela's GORE-TEX INFINIUM WINDSTOPPER Handmuff.
The product description on the Cabela's website doesn't mention it, but the one that I own has a small zippered pocket on the top which you can stuff with HeatMax HotHands Self-activating hand warmers. From the photo, it appears that the current product also includes a zippered pocket.
HACK (coming soon. . . ): I am going to make some simple modifications to the strap so that I can attach the handmuff directly to my hunting saddle.
