There are four pockets, three on the outside and one on the inside. The inside pocket is designed for the battery pack and has a velcro tab. If you are not using the battery pack, it is a handy size to just about fit your mobile phone into.

The breast pocket on the outside is secured with a zip and as are the two side pockets. The pocket on the left houses the connection wires so in effect can’t be used as a pocket as such.

Stretch Panels

There are red panels down either side of the vest of which comprise three sections. The middle section is a stretch panel which allows for the vest to mould itself to your body shape. You can tell this vest has been tailored for women.

I find the vest really comfortable to wear, it doesn’t feel like you are wearing a heated bit of clothing with wires and heating elements part of the jacket!

Heated Panels

The collar is heated which I find makes such a difference when it’s really cold as it keeps your neck warm and snug.

There are heated panels on the front and back which use Micro Carbon-fibre heat generation technology.

There are built-in power connections under each arm and the inside waist which allow for plugging in the Keis heated gloves, trousers and insoles which are also available to purchase.

A motorcycle fused power cable comes with the jacket allowing for connecting to your bike’s battery and providing a power plug which you can plug the heated vest into once on the bike.

Keis B501W Premium Heated Ladies Bodywarmer

I love my heated vest. I don’t care if I get called a wimp or laughed at, I am warm and toasty and that’s all that matters to me.

The vest itself by its very nature obviously only keeps the top part of your body warm but it seems to work that with my top half warm, my arms and legs don’t really feel the cold, at least that’s the case for me. I do wear a set of thermal base layers underneath the vest.

I bought my vest from BikeStop in Stevenage. The vest does need to be a snug fit so I would recommend trying one on first for size. It cost about £140 and comes with the bits you need to wire the plug part straight to the battery on the bike.

My other half purchased the optional extra battery pack with his vest, which cost around £80, as he prefers to keep his switched on when we get to places and are walking around.

I sometimes borrow the battery pack and use this with my vest when I’m walking the dog if it’s particularly cold, making the vest quite versatile.

If you are using the battery with the vest, the length of time the battery lasts depends if you have it on a low, medium or high heat setting. The low option will give you about 6 hours of heat, the medium 4 hours and the high two hours.

A definite purchase for even the hardened biker – its underneath your jacket so it’s okay, no one will see it 😉
