I have fought with keeping my hands warm and pain free skiing for years and should have gotten electric mittens sooner. Even in only moderately cold weather conditions my hands would go numb and feel like they were being smashed with a hammer. These mittens do the trick. I can make it through a full day of skiing on a charge using variable heat settings as needed. Even without the heater, these mittens are very well insulated and warm. Using these in wet PNW ski conditions they stayed dry inside. My one complaint is the cuffs on these with the battery packs are HUGE. it's a monumental struggle to get my shell sleeves over the cuffs.This is my second pair of Hestra battery heated gloves that I use for skiing. They work great for moderately cold days on snow.The last pair lasted me 7 years, then they stopped charging even though I got new batteries (for free from Hestra US store).I still have the old gloves. They are very durable and still look like new. I just used them for spring skiing only.I have two teenage daughters whose hands get cold when skiing and they end up going in early. They would use the iron/chemical packets as best they could but with mixed results. After some searching and reading the various reviews (both good and bad) for several electrically heated hand mittens, I decided to go with the Hestra Power Heater Mitt. The girls used them for a week of skiing. Temps were in the morning 5 deg F to a high in the afternoon of 18 to 25 deg F. In the morning they would use level 2 (medium) heat setting (occasionally they had them on level 3 for a ride up the chair) and the afternoon would bump it down to level 1 (lowest). I asked everyday at various times what they thought. Both had warm hands everyday all day long. They never ran the battery out during the day on those two settings. We took an hour break at lunch and on a couple of days they plugged the mittens in and other days they forgot. The batteries seemed to last even without charging at lunch. We did give them a good charge every night. The mittens are made from real leather and well made. The few complaints they had were that the zipper which lets you easily get the mitten on your hand (it is also the zipper for the battery pouch) is hard to zip up once you have the mitten on your hand. They would always ask me to help zip them up. Also these mittens are like any other glove or mitten, it gets moist inside after several days of use. We would prop them open to dry out overnight.Before I purchased, I read negative reviews about the batteries only lasting 2.5 hours and not all day. In the instructions with the mittens it says that on the level 3 setting you can only expect the batteries to last 2.5 hours. We never tested the level 3 continuously so I can't review that part. But just know that if you need high heat all the time you will probably need to purchase extra battery packs and have them charged and in your pocket and ready at the 2.5 hour mark. I don't think this is a negative, just setting the expectation of battery life.These gloves are expensive and I know it is not an easy decision. But I am satisfied with the purchase and my daughters are very happy as well. I would buy these mittens again.It was a little tough pulling up the zippersThese gloves come with three power settings. When it’s below 25 degrees you need to put them on setting three to keep you hands barely warm - and then the battery is dead after three hours. These gloves are best for moderately cold days only.Decent heat. Keeps hands warm for at least 2 hours on high heat mode while plowing snow in 15F weather. Heat is from top side of glove, not from working face. No heat in thumb. Little, if any, padding between a work surface, and the palm/fingers faces. Afraid to grab anything with sharp corners or edges for fear of punching a hole in what is a bit pricey pair of gloves.Overall they work great. Wrists are a bit tight, so hard to get on and off. But the wristband tethers are really great, and they are soft and warm and still get good grip on poles. Worth the money so far. Fit is tricky. Small is almost too small for female hands but medium too big.I ski in December every year and no matter the temperature, my fingers and thumbs get cold. My husband and I decided to make an investment (which was quite substantial) in these mitts and we are very happy so far. It was well below zero while we were skiing and these mitts kept our fingers warm. The charging is easy to do and the gloves are very comfortable. If they were less expensive, it would be even better but I still think that they are worth the investment because they enabled me to ski the whole day without getting uncomfortable. Much better than the hand warmers that you insert inside your gloves.Pour le ski mitaines très performantes
