That's a nice list of supplies. However, I think it's more at the Boy Scout level. Maybe (just maybe!) Webelows. Cub Scouts ... it's over their heads. They wouldn't know (or remember) what to do with most of it.

Cub Scouts need a whistle and a signal mirror. With training on how/when to use them and training to Stay Put! Cub Scouts should always be with other Cub Scouts and their Den Leader, plus other adults if they are doing outside activities away from immediate help/assistance. Sure, they should get as much wilderness and survival training as possible. That's important. But it's also important for their adult leaders to realize that they are really too young to absorb a lot of it.
