Keis Heated V501 Dual Power Vest

The Keis Premium Heated Vest is the latest in heating technology, making even the coldest rides feel the warmest. Lightweight, versatile, and wearable underneath an outer jacket, the Keis vest gives you complete heat control on the motorcycle.

The latest micro carbon-fibre panels provide the heating, emitting an even distribution of heat across your chest, and kidneys. The vest’s heating technology is more reliable, thinner and flexible than earlier versions, and provides complete upper body comfort.

Constructed of soft shell fabric, the Keis vest incorporates a lighter, slimmer design ideal for wear as an inside layer. Flexible for rider movement on and off the bike, the elasticated side panels allow for the perfect fit for both men and women. Bear in mind for more snug fit, you may need to order a smaller chest size.

The Premium Heated vest is complete with all the required wiring and easy-to-follow instructions for anyone to use, as well as dedicated zipped pockets for cable and controller to keep your system organised.

Very Impressed
So having decided that I would only ride in warmer weather as I just wasn't enjoying it below 6 deg. I thought that maybe before I give up the winter season; I would give this a go... Infinity also said if I didn't like it I could return it.. no problem... So with nothing to lose... I went for the vest rather than the Power Jacket as it's an easier fit under my Armour. The vest is really thin and elastic and so wasn't holding out much hope... however, WOW really pleased I tried... I now go out with just a shirt under my jacket and it's more than hot enough; I am now buying the heat controller to modify and reduce the output... as when sitting at the lights or travelling through town it starts to get too warm! I also found that if my body is warm my hands aren't feeling as cold as much either... Buy snug as suggested in the other reviews and it works a treat... Recommended

Why didn’t I do this before?
Recommended to get heated vests for years never did ,a long trip planned so I bought one, all the heroes who say ride impervious to the cold are wrong! These things are amazing they work so well I went into Infinity so they could show me how to use and they did ,they were brilliant I had to go back twice... I’d been plugging it in the wrong places et cetera but staff , as usual as helpful as could be The staff at Infinity are fantastic as are their products I never buy anything to do with my bike anywhere else Try one you’ll be amazed ,you get cold you get sluggish and this causes accidents these things need to be shown for what they are devices

Pairs well with the gloves
Got these and the G701 gloves wired to the bike, it’s great how the gloves wire into this, then this wires into the bike. Rode in 0 degrees at 70 and was nice and warm

Sizing is bit messed up but Infinity customer service exceptional
Keis sizes their garments in fantasy land. I ended up with the wrong size but Infinity got a replacement sorted super fast. I'd normally wear size large but a size 50 which Keis describes as extra small was my perfect fit. As for the jacket, quality looks great. I haven't tested it in use yet.

Does the job very well
This vest is great - keeps you warm without the bulk by doing the job of 2 or 3 base layers. I wear it a lot - if I have to wear something thin for commuting and have to get off the bike with no where to change but still need to look smart. I can wear a shirt with no base layers, this and then a jacket with a liner. Keeps me warm commuting shortish distances down to around 3/4 degrees. The reason I give it 4 stars is that you need it tight to get a good contact with the heating elements, but where the battery fits is also where a lot of the other electrical gubbins fits, so it can be a bit irritating when you have it as close fitting as it needs to be. I learnt this by swapping from a size that seemed ok in the shop, to a smaller size that seemed too tight at first, but is definitely the way to go. On that point - excellent service as always from Infinity who swapped it no quibbles.

I used the optional power socket which saved me connecting direct to the battery, it certainly warms you up fast and so far its been ideal. my only gripe is the heat is all around the middle and it appears the shoulder area is unheated, but saying that I was given a trial in the Infinity shop , they plugged me in and gave me a good explanation of the pros and cons of the body warmer. Overall I am happy enough with the thing and my battery is not suffering.
