This bag is meant to fit most boards. If the pump doesn't fit inside, there is also a side pocket that works perfectly for pumps. If for any reason, you have any issues just send an email to info@sup-now.com
WE took ours on several flights and have not incurred an oversize fee. Even with the board, paddle, pump , etc the bag was not fully filled, so size was about 63".
It sure is!
I would have to say yes. It can fit two 10’6” boards and zip with ease.
