It works well it keeps my hands warm when it's cold outside.

This was so much better than wearing gloves when you have to use your phone outside a lot in the winter! It’s adjustable depending on how many layers you have on and the extra space for hand warmers is wonderful!

[This review was collected as part of a promotion.] Though it might not be the right fit for every outdoor cold weather application, I continue to think of occasions where I might wear this thing, and look forward to doing so. Football games, parades, chores, walks, whatever. When what you are doing requires the dexterity of your hands and gloves aren't the best option, this will help keep the nip away. The removable extension for the waistband ensures that this will fit everyone from the kids to Uncle Jimmy who looooooves his donuts. The interior fleece is plenty warm, but with pockets for hand warming pouches, it can be as warm as you want. As usual, Ergodyne's distinct design style is also included.

This is my first winter using this product and I must say I don’t know how I got by without it before. Minnesota winters are quite harsh, especially installing solar panels on residential roofs. The design of this muff is very comfortable on my waist, I barely remember it’s there... until my hands get cold. The fleece lining is the best part, about 10 seconds with my hands inside the muff and they are quite toasty again. I suggest this for anyone who does anything active outdoors, or just to keep in the car in case of emergency.
