I can't really say anything bad about these but just understand that they are really massive. Too big to put on any of my machines they are just cumbersome. I guess I didn't read the specifications closely enough. One of them I use as some extra support on my back on my recumbent. That's how big they are LOL

Bike commuting in winter was becoming a problem because my hands would get so cold especially going downhill despite wearing very good lobsters. BarMitts reduce wind and keep warmth in. Wish I would have bought them years ago.

Company very responsive. My bars are an odd size. When I phoned, they understood the problem and immediately sent me adapters to accommodate my bar ends. Worked perfectly! Thank you.

My hand are EXTREMELY sensitive to cold. For comfort I need gloves in temperatures starting in the 50s. Being an outdoor enthusiast this has been a very difficult problem to solve. Even with high-end mittens my hands, especially my thumbs, would become painfully numb after a short time in temperature staring in the 30s. I bought a highly reviewed pair of heated mittens. This worked well on hikes but the battery wouldn't last through a chilly 35-60 mile bike. A cycling friend lent me his Bar Mitts (not the e
Extreme model) and I tried them while wearing my heated mittens on a 20 mile ride in 28 degree weather. The first positive discovery is that it was not difficult slipping my mittened hands in and operating my rapid fire shifters - the second, that I never had to turn my heater on. I bought the Extreme Bar Mitts and went for a 35mile ride with the temperature staring at 12 degrees, reaching 18 halfway through my ride, and climbing to 25 by the time I got home. It was brutally cold - a real test for my Extreme Bar Mitts. I started with unheated gloves but brought along the heated mittens. By 15 miles my hands were reaching that painful stage. The temperature was moving towards the high teens. I stopped and switched into my heated mittens, turning them on high until my hands recovered, then switched to low, got back on my bike and continued the ride. After 15 minutes I was able to turn off the heater for the remainder of the trip and the residual heat trapped in the Bar Mitts together with the temperature moving into the 20s allowed my hands to be completely comfortable for the remaining 20 miles. Given how cold it was and how terribly sensitive my hands are, I found my experience very encouraging. While I will need my heated mittens with the Extreme Bar Mitts in temperatures down in the teens, in the 20's ordinary mittens/gloves will do. For the first time I can go biking in very cold weather confident that I can keep my hands completely comfortable. I rate the Extreme Bar Mitts very high.

Don't quite fit the Jones H bar, but a bit of extra Velcro sorted that out. Not sure I like my hands confined on the bars either. However they do exactly what they're supposed to and keep your hands warm. Used down to -10C with some castelli neoprene gloves underneath and perfectly warm. (Unlike my feet, which were frozen!)

I normally don't ride in cold weather. but the pandemic renders other approaches to commuting unsafe, so I'm riding now. These mitts are essential for commuting in cold. They are easy to apply and remove, important because I prefer to use bike-shares for winter commuting. And they keep my hands from freezing. Well-designed and warm. Exactly as useful as advertised.
