I lived in Snowmass Village for 5 years and skied an average of 5 days a week wearing the tuneups bleutooth helmet from giro. Even after five years of using it I still had to take off my gloves to find the controls. My wife uses the Iez click from monster with her ipod and it's the best setup yet. The controls are on her wrist and big enough to touch with gloves or mits on but monster does not make it anymore and it's only compatible with older ipods. My idea is to have a remote that you can wear on your wrist to operate the controls on the helmet like answer and hangup calls, volume up/down, skip track, pause/play, etc. The SPH105 looks great but I know from experience that finding the controls on the hemet with gloves on is next to impossible.
Also I ride dirt bikes in the mountains too and probably going to buy one of your motorcycle headsets in combination with the 2way radio adapter. Have you ever tried to team up with one of the major helmet manufactuers to get helmets made with speakers and mic built in so all you have to do is plug in your device?
