Awesome feedback...thank you!
Neoprene layer?! Wow. This is gear for WORKING in a tunnel in sub-zero temps, correct? Jajaja...I can't imagine saying 'no' to a job working in a tunnel...but I don't think I could fly all day in sub-zero temps!
If I were to fly, say, fifteen minutes in three 5-minute blocks, in an open tunnel, where outside temp is 10C...a standard tunnel suit over clothes suited to that weather otherwise...would not be enough to keep me comfortable, in your experience?
Thank you again!
