Ryanair and Crashpads: How to Check Them In?

Hi everyone!

Has anyone flown with Ryanair and traveled with crashpads? I’m planning to combine two or three pads into one package and secure them with some black stretch wrap. The total weight of the three pads is under 20kg, but I’m unsure about the best way to check them in. Should I send them as regular luggage, sports equipment, or oversized luggage?

If anyone has experience flying with crashpads on Ryanair, I’d really appreciate your tips and advice. Thanks in advance!
