Bagley Bags

Funny story, so my sister's husband went fishing with his buddies and borrowed a darling wristlet I had given my sister.  He used the quite feminine wristlet to stick his phone and car keys in so they wouldn't get lost out on the boat.  At first his buddies teased him, then they were asking if they could put their phones in the cute wristlet too!  Ha!  My next task is to create a man bag for outdoorsmen that will hold phones, keys, chap stick, etc.  I am thinking I will make it in camo material, maybe waterproof, with a big clip on it to attach it to a belt, four wheeler or boat.  What do you think?
