In general, every Cub Scout should wear his uniform to all Cub Scouting activities, including den and pack meetings, unit outings, and any activities done with members of the den or pack.
When playing sports, going to camp, or participating in other physical activities, a pack may opt to have the Cub Scouts wear an alternate uniform, such as an activity shirt. These are sometimes referred to as Class B Uniforms.
Pack leaders should provide advance notice of any occasion when the boys should wear anything other than the complete uniform.
Here are some tips for wearing the uniform:
DO keep the uniform clean and in good repair. The official uniform is a sturdy, machine-washable garment that will last for years with proper care.
DO be sure to wear the complete uniform. A Cub Scout wearing a uniform with parts missing is not in uniform.
DO NOT wear non-BSA badges, awards, or insignia on the Cub Scout uniform or make any alterations to the uniform or insignia.
DO NOT mix uniform parts with non-uniform clothing, such as wearing a uniform cap with other clothing or wearing the uniform shirt with blue jeans. The uniform should be treated as a unit—worn in its entirety, or not at all.
Any time you are uncertain about uniform regulations, ask the den leader for guidance.
