Customer Reviews for Keis J501 Premium Heated Jacket - Black / Red

Keis J501 Premium Heated Jacket - Black / Red
November 29, 2020

Good value

Got too small a one, but rapidly replaced (excellent service) and its replacement fits well. Excellent constructions, comfortable, and fits well under my jacket over a single layer of a log sleeved 'T' shirt. Even the instructions are clear! Without connecting it up it kept me warm down to 4.5degrees. However I still haven't used it in anger and from all I've read and heard it will keep me toasty.

Difficult to fault this one. I got a Small that I wear over a thermal top. Not tried medium or high yet. Low is plenty warm enough down to 4'c Nice that the jacket had connectors for gloves and pants. I assume the power controller will handle all of these? Tried connecting it through the bmw power socket thing, but that wouldn't supply 7amps, so I wired the supplied power lead to the battery with a 10a fuse.

Winter Bliss

I'm losing a bit of weight at the moment so I didn't want to spend £1k on some winter textiles which may not fit come the following year. As such, my Keis heated jacket is a god send, I have been wearing my ventilated mesh summer jacket (RST Ventilator 5) with the Keis and being perfectly warm in the November air. Once you try heated gear, you'll not go back.

Snug and sleek

A good looking, comfortable, thoughtfully-designed inner jacket that looks like an outer jacket. Woks with or without the heating controls as it's well-insulated. Worn it to go walking as well as for use on bike. The electrical connections are cleverly designed into the fabric and pockets of the jacket. I like the fact that it's both a smart fashionable jacket and a practical one.

Just the job!

This is a well designed and well made jacket and works really well, keeping chest back and arms nice and warm. I wear it over a thermal baselayer with the waterproof armoured shell jacket on top and, although there's been no frosty weather yet, I reckon it'll be more than adequate for all conditions. I wore it today on a high and windy route, temperature around 5C + wind chill, and used the medium setting for the first time. Low is usually enough. I bought size S on the advice of previous reviewers, even though my normal size is M/L, and the fit is snug but comfortable. It's well insulated and quite warm in its own right, even when switched off. It also looks good and will be ideal on touring trips when worn off the bike, and has plenty of useful pockets. Excellent value and a great addition to the bike wardrobe.

Well made & well warm

A well designed jacket. Arms are a good length and the fit is perfect for under your bike jacket. Just remember to size down from what you normally buy. Have only used the lowest setting so far but amazingly warm across the whole body, arms and neck. It's a wind blocker too, so even without the heat it is really effective. Easy to connect to your battery too.

Thoughtful design and well made

Very good design e.g. thin but high neck line that will work well with an outer shell. Impressed by the quality of the finish. Not sure about the sizing: I'm 1.85m & 90kg with long arms so took a size S, so while the body is snug the jacket arms seem to ride up. If I'd got the M maybe the arms would've been good but the body would not be tight enough? Covid stopped the Norway trip so couldn't test it. Service and advice from Sportsbike was bloody awesome.

Quality kit

Why be without one?

Having been much acquainted with a Keis vest, eight years plus, I thought it about time I added the extras that this jacket offered. Getting a snug fit is important, so worth following the advice for a size smaller than you would normally do. The heat it provides is perfect in combating the cold. Even on the chillier days days that started with a light frost the low setting was adequate. Having the areas of the sleeves and collar heated in addition to the body makes a perfect combination for keeping the rider focused on riding. You soon notice how warm you have been when you disconnect from the bikes power cable. Don't use this jacket without the controller as the high setting is hot. The joy in not having to layer up resulting in a level of restriction in movement is most welcome. It is well made and fits like a glove.

Questions and Answers

Questions and Answers

  • I tried on size 58 in a store, what size is that? XXL? XXL? Thanks

    February 20, 2020

    Size 58 equates to an XL as per our size guide

  • Will the heat controller supplied control the jacket & heated insoles simultaneously ?

    January 18, 2020

    The J501 heat controller connected to the primary garment will only control the heat setting of the primary garment. Use an optional Inline Heat Controller to control the heat setting of any other additional connected garment, such as insoles.

  • Hello I am only 5 foot 4 inches tall but have big hips I normally take a 18 size top and 20 bottom is there a lady that understand my size and can help on what size in this jacket I should chose .Thank you .

    December 5, 2019

    Hello there, The best way to go ahead with a good fit would be to measure your chest and compare the sizes in the size chart. The jackets are elasticated so most people choose a size smaller but if you feel like your hips are big, you could stick to the size you measure closest too.

  • When will you have the size 38 inch chest in stock of the Keis heated jacket?

    April 27, 2019

    Unfortunately we will not have any further stock now until around September, apologies.

  • As pillion my arms get very cold even with many layers on. Can anyone tell me if the Keis J501 keeps the arms warm and what parts of the arms are covered by the elements? Any advise would be welcome!

    March 26, 2019

    Hi, the J501 has heat panels on the chest, kidneys, arms and collar. The panels on the arms run from the top of the outside of the arm to just above the sleeve zip.

  • As I frequently travel with a pillion passenger can you connect/power two Keis J501 jackets from a single motorbike?

    May 29, 2018

    We can see no reason why not - you would need to check that your charging system is capable of taking the draw of two jacket and any other accessories that you are running. The current draw of each jacket is 7A.

  • Does the Keis j501 jacket have the distribution system as the X25 jacket-for the Keis gloves ?

    February 23, 2018

    The Keis vest is able to operate on its own or integrate (connect) with Keis heated trousers, gloves, or insoles, via convenient built-in power leads and/or sockets.

  • How does it connect? Cigarrette lighter type plug?

    February 22, 2018

    The jacket comes with a motorcycle battery connection loom, if you wish to connect it to 12v socket you would need to purchase the Keis Accessory plug lead separately.

  • Why can't the power pack be used with this? Are there any full length sleeved jackets that it can be? I have multiple biked and would rather not be wired to them

    January 10, 2018

    Unfortunately the J501 jacket would require too much draw from the battery pack. You would be able to use either the Keis V501 Premium Heated Vest or the Keis X10 Heated Body Warmer with the use of the battery pack but they are not full sleeved jackets.
