The ThermaFlow 4.0 bib is designed for outings in cool weather conditions, when comfort, coverage, and space are needed. Made from ultra-stretch Leatt WarmYarn fabric with a brushed interior, it provides insulation without compromising breathability or mobility. The upper is designed for moisture management under the jersey and jacket, while the super-soft, ventilated shoulder straps ensure comfort from start to finish. The integrated Elastic Interface chamois is specifically designed for gravel and semi-aggressive riding positions, with dual-density foam and a ventilated front for optimal support even over long distances. Two mesh cargo pockets on the back and two on the legs allow you to keep essentials within reach, while reflective details increase visibility in low-light conditions. Treated with PFAS-free DWR and made from bluesign® approved materials, it is the ideal bib when the temperature drops and the kilometers add up.
