"The ThermaFlow 4.0 Bib is built for cool-weather rides when you need comfort, coverage, and cargo. Made from Leatt’s ultra-stretchy WarmYarn fabric with a brushed interior, it offers insulation without compromising breathability or mobility. The upper section is made for moisture management below your jersey and jacket, while super-soft, ventilated suspenders stay comfortable from start to finish. An integrated Elastic Interface chamois is designed specifically for gravel riding and semi-aggressive riding positions , with dual-density foam and a ventilated front for long-mile support. Two mesh cargo pockets on the back and two on the legs keep essentials close at hand, while reflective accents increase visibility in low light. Treated with PFAS-free DWR and made from bluesign® approved materials, it’s your go-to bib when the temperature drops and the miles stack up."
