Very good article. My dad uses neoprene work gloves all the time because he works in a lab where he's often exposed to cold materials. Of course, most of the time he uses disposable neoprene gloves since he touches so many different chemicals to avoid cross contamination and that kind of thing.
I also use insulated neoprene gloves when I bike. I do extreme biking (you know, trail biking, biking through rivers, etc), and so I always keep a pair of fingerless neoprene gloves around so I can be sure to have a good grip whatever I go through.
It is really, really important to get the size right though -- I had a friend who got too large neoprene gloves, and she got blisters like you wouldn't believe!
