I ordered these for my son to use on his four wheeler this winter. These are built very well and fit perfectly. The size large fits just as I expected. The gloves feature two separate heating zones that are controlled independently. The controls are easy to operate. A long press on the button for each zone will turn it on and light up the button. Quick presses of the button will cycle through the heat modes. Red for high, blue for medium and green for low. These offer a lot of protection with the hard plastic area around the knuckles and the extended cuffs. Despite the bits of rubber and plastic "armor" scattered around, they are very comfortable to wear. I did a full 100% to 0% high heat mode, both zones battery test and I was very impressed. I used my wife's dual probe meat thermometer to measure temperatures throughout the test. I had the probes in the index fingers of each glove. At the start both gloves were right at 70°F. At 5 minutes in they were both near 100°F. At 30 minutes they were around 120°F. They seemed to hold that 120°F until the around the 3 hour mark when the batteries were just about dead. At 3 hours and 22 minutes, both batteries were finally dead. By the time the batteries died, the gloves were still at 100°F. With this kind of battery life, if you used them a little more conservatively - low or medium or only one heat zone - they could possibly last all day. That's some awesome battery life. The batteries are also made really well. They are solid and charge via USB C. There are four battery life indicator lights that come on when you push the little button on the side of the battery. All of that battery stuff is awesome, but the best part is that you may not need any of it. These come with a fused wiring harness to wire directly into your machine to power the gloves while simultaneously charging the batteries! The wiring harness has two magnetic ends that snap right into place on the gloves to power them, and since they're only attached to the glove magnetically, they'll pop right off if you need to jump off the machine quickly. Compared to the cheaper gloves he used last year, these are well worth the upgrade.
