Swim bike trunks by Thief & Bandit, size 7/8, white cactus, spandex and lined

Worn a few times and loved. these have a thin lining for modesty. printed spandex (not screen print) with cactus design. My son loved these to swim and play around in. No size or materials tag. Size is 7/8 (age) and material is stretch spandex. See photo for a small mark, not too obvious in my opinion.
