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 refered to as Class B Uniforms (the Yellow T-Shirt)

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.

And at any time you are uncertain about uniform regulations, ask your den leader for guidance.
