There were two things that I found disappointing. The first is the lack of Aerogel on the sides of the fingers. I don't understand why Aerogel is only on the finger bottoms. The sides of the fingers make contact with objects as much as the bottoms. The second issue I have is the insulation on the back of the glove could be better and what is really annoying is the insulation only covers 3/4 of the back leaving an area near the wrist where the cold cold comes through especially when it's windy.
