Good expansion of the heated jackets.
I will use this any time I am working outside to keep my hands warm or re-warm them on the job.

I like the 3 stages of heat, and the adjustable back strap for different size people, and for adjustment depending on what I am wearing.

Only thing I don't like is the holes the hands go in are not quite big enough for my hands. I have to push and twist my hands a little to get them in the holes.

what hand size fits the hand warmer
Rawle on Oct 11, 2015
BEST ANSWER: This product is one size fits most.
Can this hand warmer be used with work gloves on? I work in extreme cold conditions and use work gloves as well as sometimes a under glove etc. Will the opening on this work or allow gloves to be used or have an opening that adjust to allow gloves to be on etc. Thank you.

It doesnt appear that you would have any problems using this hand warmer with gloves however, we would recommend that you contact Milwaukee's tech support to be certain. To reach Milwaukee directly, please call 1-800-729-3878
