    Connect & power

    Connecting the supplied motorcycle power lead is quick and easy.

    Please Note: 

    Due to the 3.3A high current draw, we do not recommend the the powering of the heated trousers via a portable battery, as the battery will only have a short life if the trousers are set on full power. We suggest connecting your heated trousers to your vehicle battery - either via the supplied vehicle battery power lead, or connect the trousers to a Keis heated upper-body garment (jacket, bodywarmer or vest) which then connects to the vehicle via its vehicle power lead. 

    Connecting and using an optional Keis Power Controller with your Keis Heated Trousers. 

    Powering your Keis Heated Trousers from your Keis Heated Jacket, Vest, or Bodywarmer.

    Connecting Keis Heated Socks or Boot Insoles to your Keis Heated Trousers.

    Please note: If you are planning on connecting your Keis T103 Heated Trousers to a set of Keis S102 Heated Insoles, you will need a set of male-to-male connection adaptors.  You do not need these adaptors if your plan to connect your Keis T103 Heated Trousers to the new Keis S302 Heated Socks

    love this item could have done with a size up though


    Used these a few times now and not only do they fit perfect, but they keep me warm and when used with the controller they keep me just right no matter how long the ride.

    Well made but far from perfect

    Keis's heated pants are really, really well made. I would not be shocked if these pants truly lasted as long as a solid pair of blue jeans, and given that you are only wearing them one season out of four (unlike said jeans), you'll have them for life.

    The heated panels also heat up instantaneously and work incredibly well.

    But would I buy again? Probably not. Three criticisms:

    1) Keis's connectors are proprietary to Keis, meaning that you need all Keis gear or none at all.

    2) While the heat is great, the location of the panels is not that well thought out. To make the pants comfortable and to keep the heating panels close against the skin, Keis made the back half of the pants a stretchy material. This means that your lower back and your hips get no heat at all. In other words, the parts of your body that tend to get coldest on a motorcycle due to lack of wind protection relative to your knees, gets coldest.

    3) The panels tend to slide inwards, heating your inner leg and thighs. Again, it's the outer side of our legs that need heating. If you've ever ridden a bike with a hot engine, you know that it gets nice and toasty on the inside side of your legs. It's the outside that needs the additional heat.
