These gloves arrived on the perfect day. It's been warm here so far this fall, with temps in the 60's and 70's mainly. But today it was in the mid 30's with a slight breeze. It was a good day to see just how much warmth these gloves can provide.To begin, these are NOT winter gloves. They are thin, uninsulated, and close fitting. These are intended to be 3 season (spring, summer, fall) gloves. Which means they are not bulky.The back of the hand is covered mostly in a white/gray/red synthetic mesh for breathing and letting sweat escape. The back of the index finger and middle finger are covered in a stretchy black soft shell material that can also breathe for coolness and drying. The back of the thumb is covered in a soft microfiber for wiping sweat or snot away. There is a big stylized flap with Velcro to lock the glove in place once you have it on. Some people have complained about the size of the flap but the size makes it easy to grab and it doesn't affect the comfort so I don't really care about the size or shape.Moving around to the palm side, the middle, ring, and little fingers are a gray microfiber cloth that mimics the look and feel of suede. The palm, thumb, and index finger are micro fiber faux suede again but this time in black. Oddly, there are perforations for breathing in the little finger and ring finger but nowhere else. But the most noticeable thing on the palm side are 2 huge silicone gel pads.Lastly, on the palm side, at the tip of the thumb and forefinger are two touchpads for use with touch screen electronics.....aka your phone. Both pads on both gloves worked fine for me. They were very responsive and reliable. But given that they are gloves, I don't see myself typing text messages with the gloves on. They block out the keyboard so I can't see what I'm typing. But for app navigation in MapMyRun on my iPhone 11 Pro, they worked perfectly.Some observations. The back of the glove looks like it will shed body heat and perspiration pretty well. The microfiber on the palms is pretty grippy. I had no problem operating the grip shifts on my mountain bike. I had concerns about the silicone pads being in the right place but after using them, I'm happy with the contact area of the pads on the grips of my bike.The fit is perfect for me. My hand measures about 10" around the palm near as I can tell. I usually take a L or XL in gloves and this time I ordered the XL because I didn't want a super tight fit, snug but not something I'd struggle to get on and off. The XL is exactly the fit I wanted. They are snug but I'm not stretching the glove to get my hand in. The Velcro closure locks them securely in place. And all of my fingers go precisely to the end each finger on the glove. I can't complain about anything regarding fit. Also, the gloves flex and move well with my hands. They feel natural from the start.So what about the cold question. OK, full disclosure, I live in the Northeast and I've been a trail runner, backpacker, biker, and skier my whole life. I LOVE cold weather. Hot weather kills me. I can't wait for winter to arrive every year. I can walk around all day in 35 deg F temps in jeans and a button up shirt and be perfectly comfy. People think I produce abnormal amounts of body heat in response to cold. So take what I'm about to say with that in mind.I could easily use these gloves down into the high 20's for an hour and a half on a mixed trail and road ride. This is exactly what I need. When I'm exerting myself I need to dump heat more often than I need to retain it. I just need a little protection from the wind and a layer of fabric between my hands and the bike's grips. One other point. These gloves make no claim to be water repellent or waterproof, and they absolutely aren't. They will soak through pretty quickly.With that said, if you're like most other people I know and you don't love the cold, I'm betting the sweet spot for these gloves ranges from about 50 - 80 deg F. Above 80, they will likely get sopping wet from sweat. Below 50, you're gonna start to feel the heat loss. My quick solution for extreme conditions would be to pull the liners out of my mountaineering gloves and just pull those shells on over these gloves. That provides a waterproof, windproof shell for rain and snow along with a huge gauntlet that covers half my forearm. If you don't have a glove with an outer shell you can pillage, yer gonna want a dedicated winter glove.Hope this helps with your decision.
