The size guide is roughly accurate, XL fits reasonably well on EU size M or 48/50. Current draw from the USB input is ~1.85A when heating both the front and the back, and ~1.10A for only the back. At the lower temperature settings this draw is intermittent. The size of the battery pocket is around 16x13 cm (on an XL unit). The LED at the front is lit constantly while the vest is on, and it's way too bright. Need to wear a layer on top of it to not have it as a distraction / look like an idiot outdoors. I ordered from a CZ warehouse with 4-10 day estimated delivery. The actual delivery time was 22 days, and the item was shipped from China. Nothing happened for more than a week after my payment. I had to write several messages to the seller to get a valid tracking number after about 2 weeks. Even that wasn't the actual tracking number of my package, only the one for the last mile local courier (DPD). Don't shop here if you are looking for quick delivery from the EU.
