Overall these gloves are a great addition to my ice climbing quiver. Depending on the conditions, the gloves I I use are the Alibi, Project, Extravert, Luminary, and now these. I see the Vitalys replacing the Luminary gloves, which are warm but don't have as much dexterity. I've climbed in these at ~5 degrees with 15-20 mph winds and was plenty warm in these even while climbing. The only thing about these is that they have a bit of insulation on the palm and front of the fingers, which is great for warmth but reduces dexterity and feel a little bit (which is compounded somewhat by fingertips that feel a tad loose - but that could just be me). For very cold conditions, that's a compromise that often needs to be made and that's where the Vitalys shine (compared to the Luminary, they have comparable warmth and better dexterity), but for milder temperatures I'd recommend something a little thinner.
