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.
Earning Loops and Pins multiple times
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."
