Size Chart

- +

These black jammers feature femur bones on the front and back.

Our Boy's Jammer swimsuit is ideal for both competitive and recreational swimming with a streamlined fit and longer leg to reduce drag in the water. The fit has a medium rise for full back coverage and the leg hits just above the knee.

Why we love this jammer:

  • Smooth flat-lock seams for comfort
  • Flat, non-slip drawstring
  • Lined for modesty
  • Sublimation printing is fade-resistant
  • Fabric imported from Italy
  • Made in California

      Passion doesn’t come in solid colors. For those who are passionate about water sports, from swimming to surfing, standard swimwear just doesn’t cut it.

      Sizing Guide

      For Best Results, Follow These Instructions:

      HIP: Measure around the fullest part of your hips. Keep the tape horizontal to the floor.

      WAIST: Measure around the narrowest part of your torso, typically across the navel and the small of your back. Keep the tape horizontal to the floor.

      CHEST: Measure the fullest part of the chest, be sure to go over the shoulder blades in back. While chest measurement does not impact suit sizing, having the measurement on file will simplify other product orders.
