Scot K.wrote a review of Black Diamond Arc Glove on December 2, 2011
I bought these because of the great price and the fact that Black Diamond is a top notch company. I was disappointed with their lack of warmth provided, even on 30 degree days. I guess I shouldn't have expected much from 40g of insulation, though. The Arc is maybe a spring ski glove, but not a real good winter glove.
The B-Dry insert and feel of the gloves is great, but just not very warm.
