Regarding that restriction in the upper thigh: current Bullet has a slide lock bungee inside the pockets as the pocket support system. If that is snugged up, you will restrict the fit on the thighs. So it doubles as a thigh adjustment! Loosen that up and I bet your problem is solved.
Other random notes:
I really wish my L/XL was 2 inches longer. Neck ring really scrapes my head getting out, but next size up too baggy for my frame. It has been suggested that I try an L/XL skin over a 2x/3x core. Haven’t done that yet, but it makes sense.
I also am annoyed by the Bullet ability to hold water. Might want to try a Sport with tech shorts. The Sport is more durable than you think - I was told that when Whites introduced the Fusion they produced a run of extra Sport skins expecting people to wear them out, and it didn’t happen.
Best way to take the suit off - have buddy grab the heel and pull out.
I have been wearing sock liners plus 3mm neoprene socks, and rarely feel a chill in my feet.
