Cub Scout Uniforms
The required parts of the Cub Scout Uniform (for Pack 706) are the blue Cub Scout Uniform (Webelos may wear the tan uniform), and the rank-specific neckerchief and slide. Uniform shirts should be tucked in.
Lion scouts are to wear the Lion T-shirt from BSA as their uniform.
Official BSA pants/shorts are encouraged but not required. (In lieu of official pants/shorts, the pants or shorts worn, should try to match the uniform - sweatpants/gym shorts discouraged)
Rank-specific hat is optional.
Official belt is optional, but often the Scouts like it as they are awarded "adventure loops" (belt loops) that fit on the official belt.
