I bought these Hyperlite gloves and also the Seirus All Weather gloves two weeks ago. After reviewing both in person, I sent the All Weather pair back; the Hyperlites are just what I was looking for. First, they are very form-fitting, they really fit like-a-glove. They are thinner than I expected. But not too thin, the high quality really stands out. I put them on and immediately put my backhand under a faucet...yep they are waterproof, which is very cool. I did wear them for extended hours in 35 degree weather.  My hands ended up getting a little cold, but you cannot expect miracles without having a very thick glove. These gloves make great driving gloves. They also make great tactical gloves for shooting weapons or things like that.  Or if you have work to do in cold weather that requires a less-thick glove, these are perfect. Also, these gloves are nice enough to wear to formal functions outdoors in cold weather.  Sizing: the Large size fits me perfectly and I am a tall guy.  If you are in between sizes, I would probably go with the smaller size for the snug fit.  That's it. I rarely give out 5-star reviews, but these gloves are really pretty awesome.
