Storage box on the cheap

Wanted a little storage for longer runs.been using a backpack for a while but strapping it on and off and the fact it’s always soaking wet got on my nerves.this cost a grand total of about 45$ and its sealed so should stay dry inside..on with a couple u bolts so its quick to remove.have everything is need inside …first aid kit,tools,spare belt ,rope ,straps ect.very happy with it…plus its back and yellow lol.
