How does jammer sizing work?
Jammer sizes correspond to waist measurements in inches. Refer to the Funky Trunks size guide to find your best fit.
How do I care for this jammer?
Rinse in cold fresh water after each use and lay flat to dry. Avoid wringing, machine washing, or tumble drying to preserve the fabric and print.
