Something like the Maratec SatCom bag would be perfect only they're too short. Maybe something like a bat bag? https://smile.amazon.com/Easton-E100T-Baseball-Tote-8-5-Inch/dp/B00LFL5FWG Last month I snagged a racquet bag that my 10.3 fits into like a glove.

Depends how much equipment you have. I have just my bat, cleats, batting and catching gloves and a couple of balls and everything fits with plenty more room in this...
Had mine for 3 years already and not a single tear.
So its not available on Amazon but walmart has one that looks exactly the same, just in blue or red. Mine is black.
