Review on Outdoor Hand Warmer Muff - Ideal For Hunting, Fly Fishing, Camping, And Hiking by Tom Reid

Definitely keeps your hands warm if you throw a couple hot hands in it prior to hunting. I have a 40 waist and it had plenty of room for bigger users or you can wear it around your neck. The zipper pouch was large enough for my new iPhone 12 max. It was a little difficult to get my hands in and out while wearing gloves/fingerless mittens. I typically wore glove liner gloves after the difficulty with the larger gloves.
