This short is the new and improved version of the FI.13 with a improved Lycra Design and S2 Fabric. Eight panel bib short. Assos Swiss quality. The world’s first elastic insert bib short. The insert is designed to follow your pedal stroke movement. Stitches are applied to the FI.13 / S2 insert immersing the fabric from the skin by reducing stress and friction that can cause irritation. The insert also optimizes muscle compression while reducing muscle fatigue. A special panel design invented by Assos reduces fabric bunching when in a tuck position and helps to further decrease unwanted movement. An elastic micro fiber meshnet is inserted between the braces covering a large part of the back. The micro fiber mesh-net eliminates slipping by added bracing, improves the overall fit and increases volume of evaporation to the short. Sizing based on height.
