It’s so warm and comfortable
27 Oct 2025 by Nick
Wow this jacket is SO warm and comfortable too. I have an old version of jacket which is about 5 years old and well used and needed replacing. It was good but this one is in a different league in terms of warmth and comfort. The heat is so much nicer all over - no cold or hot spots just consistent warmth. The material also has a bit of stretch making it very comfortable. My old Keis jacket felt like a straight jacket. I did buy the Keis Ultraflex first but it developed a fault and went back. I can therefore compare it to that and the heat in this jacket is much better. Highly recommended if you ride all year it’ll transform cold weather riding.

These Keis J505RP heated jacket is great. People tell you that it is a game changer but you don’t believe them till you try it.
Just run the supplied cable to your battery or get a battery pack and you good to go.
Warm neck, back, arms, chest. Not only is it warm but it is also good looking and comfortable.
Did a small trip in 10°C and setting was at low and still was warm and cosy.
Top product.

This is an amazing jacket, if you commute through the winter, this is a must have accessory, probably more like a necessity
The jacket is warm on its own, but when heated it changes gears and your comfort takes on a whole new world.
Try it, you’ll love it

Fabulous

These Keis jackets are probably the best thing you could buy yourself if you ride a bike.
Windproof, and for cold rides it’s like having an electric blanket around you.
Arms, neck back and chest is toasty warm, or turn the heat down if you get too warm.
Lifetime warranty on the elements, Keis and SBS are simply the best to deal with.
I would not ride my bike without it. I even bought myself the waistcoat version for the summer, as evenings can get a bit chilly.
Get yourself one , you won’t regret it.

Game changer
06 Mar 2025 by Luke Q
Wish I bought this years ago. It gets very warm very quickly in all the right areas, looks great as well.
I'm 6'6" and went on the advice that I should go down a size to ensure this jacket works best. Glad I did as its a nice snug fit and the sleeve lengths are spot on.

Keis Heated Jacket
22 Feb 2025 by Liam K
Just the ticket for the cold weather. They're jacket is warm when worn under my motorbike jacket. But it's transformed once the heat is turned on. The level of heat produced is tremendous. It's like riding into the fires of hell. Central heating on the move.

Game changer
27 Jan 2025 by Nick
I feel the cold, especially in my hands. Bought this jacket and the keis gloves, and can honestly say they worked superbly well. Wasn't expecting them to be this good. Had to actually turn them down. Used them in about 2 degrees which on the bike feels colder. Perfect, a complete game changer!! Highly recommend.

The jacket is great, with a quality feel. It has transformed my winter riding, improves my concentration and extends the duration. Once plugged into your bike the heat is instant and the entire jacket is covered. You wear this under your protective jacket. The fit is accurate to the sizing guide.

Worth it

The setup is very easy, and it distributes heat quickly and evenly. Even at 6 degrees Celsius, it provided driving comfort at medium usage, and I didn't feel cold.

Worth every penny

Held off buying keis as the price always put me off, alot of money just to be warm, however took the plunge when I realised they did lifetime warranty on the heating element. The jacket isn't too thick but is really warm even without using the heating. Nice stretchy panels at the side ensure good close fit without restriction.
The Glasgow staff were a great help ensuring I had the fit and jacket type that suited my needs best.

Questions and Answers
Does this jacket come with wiring to fit a standard optimate installed 12v connector AND is this the version with removable sleeves ? Thanks????
November 11, 2024This heated jacket is provided with a power supply lead only, and you would therefore need to purchase the Keis Power Supply Lead to Optimate Battery Connection Lead separately (Quick find: 187465 and option SAE Type). This version does not have the removable sleeves.
Does this jacket support the battery packs and link to other KEIS gear
