Budget alternative to Patagonia Men's Baggies™ Shorts - 5"

Hey, does anyone know any good budget alternative to the shorter, 5" Patagonia baggies in European markets? I've been scouring second hand platforms for some but it seems they are extremely wanted. I'm going on a trip soon to Spain and want a lightweight short for hiking and swimming, all in one.

Any recommendations would be greatly appreciated!
