“GREAT - super warm even without turning it on. I turned it on one time - turned it on to take the edge off for an hour or so and then I didn't turn it back on. Wind and water proof it blocks the wind great! One thing to keep in mind it doesn't breathe (just like the jacket) so I carry it in separately and then put it on if I need to. It's quiet and comfortable. But great product - I'll actually use it as snow pants around the house if it ever snows again. The battery pocket is the left leg pocket - which I wish it was located differently - I felt like I lost that pocket to use with the battery there - but other than that - great product.”
