How long does the battery last on a charge?

Runtime depends on the heat setting; high heat drains the 5V battery fastest. Expect a few hours at most on the highest setting, so carry a spare for long tailgates.

Yes, at 30 degrees, but disconnect and remove the battery pack first. Let it air dry rather than tumble drying, which can damage the wiring.

How does the sizing run?

It is unisex and offered from S to 3XL. The puffer cut is roomy enough to layer over a hoodie, so most buyers can take their usual size.

Does it come with the battery?

This version is sold with the 5V battery included. Check the listing you buy from, since some heated gear is sold as vest only.

Is it warm enough without turning the heat on?

It is a lightweight puffer, so it works as a mild-weather layer on its own. For real cold, use the heat or wear it under a shell.

How does it compare with a standard heated vest?

It offers similar panel heating but adds Bills branding and a simpler control setup. Rivals may offer more heat zones or app control; this one is about team spirit.
