The ThermaFlow 4.0 Bib is designed for rides in cool weather when you need comfort, coverage, and storage. Made from Leatt's ultra-elastic WarmYarn material with a brushed interior, it provides insulation without compromising breathability or freedom of movement. The upper area is designed for moisture management under jerseys and jackets, while super-soft, ventilated straps sit comfortably from start to finish. An integrated elastic-interface seat pad is specifically developed for gravel riding and semi-aggressive riding positions, featuring dual-density foam and a ventilated front area for support on long distances. Two mesh cargo pockets on the back and two on the legs keep essentials within reach, while reflective accents enhance visibility in low light. Treated with PFAS-free DWR impregnation and made from bluesign® certified materials, it’s your top choice when temperatures drop and miles add up.
