Title: Great at 20°F, good at 10°F, insufficient at 0°F
Content: The Good: 1. Definitely waterproof. Ran tap water over them at full blast for ages when they arrived, and no moisture penetrated. The surface dried almost instantly. 2. You can actually move your fingers well enough to bait a hook. I am a woman with small hands, so even with the S there was a little room at the end of the fingertips. When a small trout swallowed the hook and I needed pliers to get him off, I couldn't quite sort it with the gloves on. But I could get most fish, I could put maggots on, I could adjust my reel, and I could get things in and out of my pockets. 3. Pretty insulating considering the flexibility. I ran the hottest possible tap water over them for several minutes and my hand felt slightly warm. I ran the coldest possible water over them and felt nothing. I plunged my hand into the ice hole several times for approximately 10 seconds at 15-18°F and felt nothing. I plunged my hand in the water for a few seconds at about 10°F and felt nothing. (I kept my hands out of the water at -3°F, I'm not insane). 4. I was able to put a hand warmer in the palm without making the wrist gap (and let in cold air). Of course your fingertips will get cold first so I don't know how much good this does, but it won't hurt. The Bad: 1. The insulation does have a limit. I have used these at multiple lakes and temperatures, so I think I have a pretty good idea of how warm they are. Around 15-20°F, they were totally sufficient on their own. Down around 10°F I really wanted to keep my hands in my pockets as much as possible and I would have used a second glove layer if I could have. At -3°F my fingers got so cold I lost feeling and couldn't grab a maggot or bait a line. It doesn't matter how much dexterity a glove allows if your hands get so cold you lose it anyway. 2. Some reviews suggested using a warmer glove in addition to these. I planned to use my warm mittens with finger flaps on top of these but they didn't fit. I still think that basic idea would work, but these are thick enough that you would need large mittens/gloves,-specifically sized-up to be an outer layer. I don't see how you could wear gloves under these without losing dexterity. 3. The fit was surprisingly good but not perfect, and neoprene doesn't allow for any squishing or adjustment. It would be nice if they made some women's sizes, as our finger length and width relative to our palm dimensions tends to be proportionately different than men's, and a neoprene glove works best when fit perfectly. But the size was workable, and the fingers stiff enough that a bit of extra room did not prevent using them. Overall: I struggled with how to rate these because there are no magic gloves. How can any material allow you enough flexibility and motion for fine motor control, entirely repel water, AND keep you warm at literally any temperature? I'm sure it's impossible. On the other hand, negative temperatures are totally realistic for ice fishing. It's reasonable to prep for those temps and to want gear that works in them. I am glad I bought these gloves, I will continue to use them ice fishing, and I may even buy new mittens specifically to pair with them, but I have also decided to reserve the 5th star for a pair of gloves that can take any temperature I can take.
