Activity Uniform - What is it?

The Activity Uniform is a Scouting-related T-Shirt and scout pants.

Field & Activity Uniforms are often referred to by our Troop as Class A & Class B Uniforms though that terminology is not used in any official BSA publications and is not correct. (The correct terms would be to call them Field & Activity Uniforms following the BSA terminology.)
