They match the OEM ones!
They are just as good as the OEM caps and fit perfectly. I found if you put a small piece of rubber with adhesive on 3 of the tabs they hold better. I did it on all of them including the oem.

Good buy and good replacement for stock
I can’t keep these on my UTV, so it’s good to find a reasonably priced alternative.

Definitely keeps your hands warm !!
Color: Black
These fit nicely on a H.D. Road King. If you bike has heated grips you can drive in 30 deg F weather with only a thin pair of leather gloves. Update: They kept our hands toasty with the heaters on Level 2 and just wearing a thin pair of leather gloves (for grip) while riding in temps down in the low 30's, high 20's. I would definitely recommend these... the photo in the ad is pretty indicative of how they fit on handlebars. They're really designed for ATV's that have no turn signal lamps on the handlebars. Without modification, they do cover the handlebar mounted turn signals on a Sportster, but not on a Roadking. The draw string that seals the mittens around the handlebar could have a more positive grip to stay closed... we wound up double tying it around bar and that works great. The thing we like most aside from how warm they are (the lining feels great)... is that the cuffs are fairly rigid and don't collapse when you take you hands out (like the photo) which makes it super easy to pull you hands out and put 'em back in again. That's really important at a stop light, but even more important when flying down the road at highway speeds... you just can't afford to be fooling around trying to thread your hands and a coat sleeve back into mittens that are limp and flop down closed when you take you hands out... I hope this help... be safe !!
