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
Belt Loops & Pins tie directly to these requirements: Tiger / Electives, Wolf / Electives, Bear / Electives, and Webelos Activity Pins.
- "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."
