  • Fleece Seat Liner: Offers light cushioning for the bike segment but disappears when running.
  • Flat-Lock Stitching: Ensures seamless comfort and prevents chafing.
  • Raw-Cut Leg Endings: Provide a sleek fit with internal silicone grip to keep the shorts securely in place.

Who is it for?
Triathletes seeking a lightweight, comfortable, and high-performance bib short for training or racing, especially those who don't require a full seat pad.
