Keis B601RP UltraFlex Heated Bodywarmer - Black / Red

After being impressed by the performance and simplicity to use of the G309 gloves last winter I decided to purchase this bodywarmer. Although its not been cold enough to wear as yet its there ready. The sizing guide is accurate and very helpful. The fit is snug as described but not over tight. It is easy to make all the necessary connections and feels comfortable under my riding jacket.

Great fitting warm and very comfortable underneath my jacket size was just right for me xxl .
The only gripe I’ve got is so much wiring even the controller is bulky in the pocket but it’s only minor issue for the warmth you get

This has transformed winter riding for me. I actually look forward to going out in sub zero temperatures now. Great piece of kit.

I bought this to replace my old Keis X10 vest which was still going strong but had seen better days after years of use. The ultraflex material is a lot lighter and thinner and fits under a fleece a lot easier. The vest has a heated collar which is good and the same levels of control as my old vest with the included controller. I've also got heated insoles and heated gloves which attach easily. The gloves can be controlled separately even if the vest is switched off. I ride in all weather's and seasons and wouldn't be without the heated kit.

Now this is the dogs do da's it does exactly what it says on the box, had to wear it over the last few days and will again today, it is fantastic, why I haven't bought one of the before I don't know, next week the heated gloves.
Listen, if you want heated clothing, these are fantastic

This Keis body warmer is perfect for keeping your whole body warm by keeping your core warm. The quality of teh garment is excellent and fits snugly although i would recommend a size down from the clothing you normally wear. The three stage heat settings are very different and work well from warm, hot and very hot...so keeping you cozy in all temperatures from a chilled summer morning to a deep freeze winters ride (i know living in Scotland) With the option of battery or direct wired to your bike the flexibility for using this garment is great. Also, the additional options of wearing Keis other gear such as under trousers or gloves - these all plug directly into the vest too. The main reason i got this was rather than layer up loads and feel like Mitchelin Man on the bike which can be uncomfortable and restrictive, you can wear this and a few other thin layers and be cozy but still have the flexibility....for me this is a big selling point. My friends suggested i was an old man getting this until they saw how good it was and teh flexibility i get riding in colder weather without looking and feeling bulky...so they have invested in one too. I'm a sports bike rider and still think these are a must for a UK rider and not just for hard winters and tours. Go get yourself one....you'll never look back and it will be the best thing you'll spend on clothing .

I previously had the soft shell type bodywarmer and the keis jacket. This is so much better. The others I found restrictive and a bit bulky. This is very soft and flexible you hardly know you're wearing it. You can feel the wires when not wearing but don't notice them when it's on. I haven't tried with battery yet but plugged into bike on low on a 10 hour ride in the rain it offered enough warmth to be comfortable.

Used once with the heating element on and once just as a body warmer and on both occassions was brilliant. New soft and stretchy material. Love the fact it has no sleeves so arms not cramped once jacket goes on. Really easy to use. Fixed wires direct to battery which was easy to do so not reliant on batteries. Going Scotland in September and will be using it for there and colder trips/days out over winter :)

Decided to purchase one of these just before a recent tour around the west coast of Scotland. Weather on the Thursday was cold and wet and using this under my 7 year old Rukka gear meant that I stayed dry and warm.
It comes with the controller which is a must have because i only ran it on the lowest of the 3 settings. It made a massive difference and I felt perfectly comfortable for the entire trip.
Initially I did keep forgetting to unplug when leaving the bike but the connection is designed to come away without too much effort but holds strongly enough for it not to be a problem when riding.
The heat distribution was even over my chest and back with a nice level of heat around the neck.
It's not at all bulky and felt comfortable over my merino wool base layer, with the vest in between that and my jacket.
Size wise I went off the sizing chart and ordered a medium. The fit was slightly big but I think the small would have been too snug. They recommend a bit of movement should be available and the medium allowed that.
Thoroughly recommend and wish I'd bought one years ago.
