I have used Keis stuff for years. From about 2013. Suffering from a couple of arthritis type illnesses means that Keis keeps me on the road when ever the temperature falls below 15deg c and as I cannot travel by car due to the pain this causes me, really does mean that Keis keeps my life rolling along. I decided to try the J601 as my new Knox jacket was a bit restrictive with my current Keis underneath.
It had made it much easier to move about and far more comfortable, which is a massive plus when you are already in pain and any uncomfortableness really just adds to the pain levels. Warm enough but not quite as warm as my current Keis jacket but suspect that is down to the new controller. I still have the really old controller with 4 levels which I will try.
Would I buy same again if I lost it? definitely!!
And this one folds up easier so it can go in my tail pack for the cold evenings.
Thanks Keis!

Fabulous gear makes riding in cold weather a brilliant experience just enjoy the ride without freezing to death

Since I wrote my previous review I have bought the trousers. Only problem is if you connect the socks to the legs of the trousers then the heat level of the socks is controlled by the heat level of the trousers, not always ideal, I find I want the socks on max. The solution is a splitter before the trouser heat controller.

These are great for keeping you snug on long rides, especially on the motorway when the wind chill takes effect. I've had mine for years and it's still going strong. I'd suggest the three position controller as opposed to the on/off version because even on the middle setting it can be too warm unless it's very cold outside. Essential cold weather riding kit IMO.

I tend to only wear these on long motorway rides in the winter when the prolonged wind chill has an effect even on my legs. I've had these trousers for about three years now and they are still in great condition, with no signs of deterioration. If you ride in very cold weather for long periods, I'd recommend them.

great gloves

Grate quality, lovely and toastie, definitely a must in cold weather. Bit of a faff plugging in at first use, but now I couldn't do without it.

Good so far

Great. The only pair of heated socks I’ve bought that actually work. 👍🏾

Love them. Game changer during cold rides.

Fantastic! I can now cool my feet rather than cook my feet.

Game changer, should have purchased years ago!

They are great work well

As a daily motorway, motorbike commuter I've tried loads of extreme Winter gloves, some good, some not-so-great. So, after struggling in early December, I decided to finally go for the heated glove option. At first I wasn't blown away because I hadn't learnt the proper charging procedure & found the batteries draining too quickly & was thinking of returning, but once I cracked it I've been really impressed. I only put them on below 8c and even then only on the LOW setting. I went to MEDIUM once when it was -2. They are comparable to my best Richa winter gloves even without the heating on. Will be put away in April once temperatures rise. Very happy with them. Bye bye frozen fingers.
