Verified Customer Reviews for Keis J601RP UltraFlex Heated Jacket
A perfect fit
15 November 2024 by Mike
The benefit of visiting the shop was I was able to experience the alternative jackets and their fit. The fit and flexibility of this jacket was in a class of its own with no restrictions on my movements at all, particularly around the shoulders. Choose a close fit. The downside is that it is designed more so for bike use and not so for walking the dog on a frosty morning which would have been an added benefit. There are other Keis jackets which would be more suited.
Thanks to the staff at Birmingham for their help and advice.

Toasty

Used jacket for a 100 mile round trip recently. In 7 degree temperature. On the lowest setting it felt comfortably warm. However, on the way home, the inline fuse blew. As I could not get a replacement I will have to wait for my next journey to test again.

Problem with reviews is you only write them when the product is brand new. Keis is a trusted name. Bought cheap amazon electric gloves last year and they were a game changer. Cheap jackets were almost as much as this so I bought the Rolls Royce. Fits on the bike easy. Works now all I am waiting for is poor weather.

Comfortable Warmth

I already own a Keis J501RP Premium heated jacket,
Which is excellent , but a bit bulky under a textile jacket.
This Jacket the Keis J601RP is less bulky and much more comfortable under your normal riding gear. I Highly recommend it.

Gamechanging quality riding gear

Very comfortable to wear, not bulky or uncomfortable in any way. Makes riding in cold weather a pleasure. Creates a perverse pleasure as I look forward to turning the jacket on and feel the heat making my journeys a pleasure not something to dread. Would definately recommend.

Gamechanger
11 March 2024 by John C
I don't use the word lightly but this jacket is an absolute gamechanger for winter riding. I ride all year round and this jacket has transformed my comfort levels. I suffer quite badly from the cold and this jacket, at its hottest setting makes even me nice and toasty. I use just a base layer underneath and a textile jacket over the top of this and it keeps me lovely and warm. Thumb loops keep the sleeves from riding up (other manufacturers take note!) and it is easy to set up and use. I find it a little tricky getting my arms in as the lining is a little loose near the wrists, but once it's on it is a lovely fit. Highly recommended. Just got to get some Keis gloves now - the connections from the jacket are already in place so they're a no-brainer too.

I'm enjoying the new heated jacket, great spread of heat. I've only needed it on low and medium for a 2 hour ride in the rain at 6C
Great speedy delivery from Sportbikesshop as usual

Super snuggly
17 January 2024 by Jamie N
Always stayed away from heated kit. Never wanted the faff off being connected to the bike battery. As it turned out it was an easy fit and cabling is tidy on jacket (zipped away in its own pocket and on the bike it slips away along the tank.
Extremely comfortable and warm. No need for more than a longsleeve icebreaker underneath this piece and then straight on with your riding jacket. Haven't ridden in 0c but was more than warm enough ion my last outing in 4c on medium mode.

Superb comfort

This jacket is so light and comfortable to wear and it is a stretchy material so fits perfectly. Wore it at temperature of 4 degrees and no coldness at all. Well worth buying.

Superb period.
06 December 2023 by Gordon C
As the temperature dropped I decided maybe I should invest in some heated clothing. I made a purchase of these Keis heated jacket and frankly it's a revelation. It provides much needed warmth on those chilly rides and makes riding so much more comfortable. The ultaflex jacket fits snuggly, the only negative aspect is the bulky nature of the connectors around the pockets but once you experience the warmth it's all forgotten. Recommended.

As a mid-layer, the UltraFlex features a unique 4-way stretch material, for optimal fit without compromising on movement, and micro carbon fibre heated panels within the chest, back, sleeves and collar areas.
