Great dexterity, very comfortable, durable and pretty warm. They're a pretty thin glove, so obviously not for single digits, but they have a comfy thin fleece lining and i used them with some thin burton glove liners and was warm down to about 15 F. I had my hands in the snow a lot and they never got wet using the provided waterproofing wax.
I haven't done any real backcountry since getting then, but some sidecountry hiking, and I would say they would well in that situation. For me, unless it's really cold (single digits) my hands usually only get cold on the lift and generally when I'm not moving (my hands get pretty sweaty hiking in thicker gloves) so these are great when you need the dexterity in BC for switching from ascent to decent but it's cold enough that you don't want to take your gloves off.
For those complaining about the grayeen color, it's your fault for buying something labeled as grayeen in the first place.
