And thinks with you. Strategically positioned stitching prevents any chafing when cycling. A combination of different fabrics provides enhanced breathability or more protection where it's needed. Plus it ensures muscle compression for improved performance of active muscle groups. We used our revolutionary burnout technology to create air vents in the fabric so no stitching or mesh inserts are required. This means we can make more vents in varying shapes and sizes in the garment, select different strategic points, increase comfort and reduce the overall weight. A family of innovative technical fabrics certified by Lycra? Sport that are designed to ensure extreme fluidity of movement and maximum muscular compression. The fabrics are also ultralight, exceptionally fine, breathable and resistant to UV rays (UPF 50+).
