The Keis V501 heated vest is technically identical to the V501RP, with only the colors changing. It is delivered without a temperature controller, and therefore offers only one heating level (the highest). The temperature controller is available separately if desired, but is not essential.

This heating vest is a discontinued product, with only a few sizes left in stock. Missing sizes will not be replaced and are blocked for sale.

The Keis V501 Heated Vest is the ideal heated vest for all your professional or leisure outdoor activities.

This vest is designed to be autonomous from a vehicle, and therefore powered by one of our Keis lithium Li-ion batteries: either the large 5.2A battery, or the small pair of 4A battries.

All technical information and demonstration videos concerning the connection, power supply and heating of our vests are detailed here.

Choose your usual size from the drop-down menu next to the blue "Add to basket" button. If in doubt, you can also measure your torso/chest circumference and choose your size from the table below.

If you're not sure between two sizes, we recommend taking the larger one. For example, if your torso/chest circumference is 103 cm, choose the jacket size 105 cm, i.e. M.


If the size you receive doesn't fit, you can of course exchange it free of charge. Just send us an email and we'll send you the procedure for printing out a returns slip and dropping off the parcel at a delivery point near you. After receiving and checking your order, we will send you the new size free of charge, subject to availability of course.
