My hands get cold easily.

For 35F to 45F: backpacking shell gloves, with a gore-tex type of membrane. Either by themselves above 45F, or with medium or thin liner gloves. I like that I can wash the liners, and air out the shells overnight.

For above 45F to maybe 55F: windblocking fleece gloves. These breathe quite well, but your hands will be fairly warm even if they get wet.

For around 52F to 62F: REI liner gloves, worn under fingerless gloves.

Wow, these are great. I originally got these as a second layer to keep my hands warmer in the winter, and they do a good job for that purpose.

I'll wear them all spring and fall. They are so thin, they easily fit under fingerless summer gloves. And they are quite good at wind blocking. I can shed them if the day warms up, and they are really small in my jersey pocket. I bought a second pair, in case they stop selling them, but they are quite sturdy. I haven't seen any wear in the fingertips yet.
