Hello mate I have same issue as you. Do you have a particular load out in mind or are you not bothered?
I run with a chest rig I have a an ASG special teams carbine and a Sterling 9 mm sub as back up all collapse down and fit into a dry bag . BDU's under water proof bike gear. At the site if no better option I keep crash helmet and bike gear in the dry bag chained to the bike while in the game. It not pretty it's not tacticool but it works.
