Your uniform

A scouting uniform needs to take into account a number of things of which I would say the first is the actual main use it's wearer will be putting it into.
A cub scout or scout is going to be out of doors so he needs his uniform to be comfortable and hard wearing with little chance of easily being damaged by being caught on foliage 
His footwear needs to support his feet properly so they are comfortable even after walking for a few hours and hard wearing as you go through all manner of terrain and his socks need to traditional wool mix long socks to keep his legs warm without sweating.
He wears shorts because they are healthier, allowing more of his skin to breathe and the material of his dress short and shorts is hard wearing and easy for him to care for so he always looks smart.
This is a an excellent uniform.
