They truly do help keep you warm. I purchased for my husband, but I’m finding I like wearing them more then he.

Very warm. Battery lasts a good amount of time. I definitely would buy again.

Works great. I wear women’s small and the small fit great.

I live in NY state and work on city streets. I have already used this pants twice with temperatures below 30 degrees and I assure you it works, it works very well and if they help a lot to maintain body heat.

I bought this with no reviews and took a chance. I wore this to a cold Penn State game today. It kept my lower body warmer than expected.It lasted the entire game on high and then some on the ride home. Right now it greatly exceeded my expectations. I will update review after each game if things change.
