A number of Webelos Activity Badges require completion of a Cub Scout Belt Loop. Also, there are a number of other overlaps between the requirements.
All registered Tiger, Wolf, Bear, and Webelos Scouts can earn Cub Scout Academics and Sports Program Belt Loops and Pins more than once.
- "Many Webelos Scouts may earn belt loops and pins a second time to qualify for Webelos Activity Badges. All boys may earn belt loops more than once; however, leaders should encourage boys to try different requirements and earn the pin. Packs should have a clear policy in place to determine whether the pack or the boy's family will be responsible for the cost of awards that are earned more than once."
