I was browsing the Castelli Winter 2016 catalog and came across something that I haven’t seen before. Castelli winter gloves with boa dials. It’s called the Castelli Boa Glove.
I like it, but might like it more if it was in a mitten…you lose so much dexterity with mittens that I can see giving them an easy ingress and then using boas to snug them up.
