Good prodeuct, light weight, fits right, and provides decent warmth. Ony reason for knocking 1 star is the battery doesnt last as long as they say. I get about 4 hours on high.
Pros
QUICK AND LONG-LASTING WARMTH - This heat vest comes with a 10000mAh/3.7V power bank. The USB port also can be charging smartphones. This winter vest built-in 5 heating pads, an efficient heated design makes quickly warm up even in extremely cold weather. The power bank has up to 8 hours of comfortable warmth at a low-temperature setting after being fully charged.
Cons
The vest may not be as effective as traditional winter wear
