The ThermaFlow 4.0 Bib is designed for colder weather rides when you need comfort, coverage, and storage space.
Made from Leatt's ultra-stretch WarmYarn fabric with a finely brushed interior, it provides insulation without compromising breathability or mobility. The upper is designed to wick moisture under your jersey and jacket, while the extra-soft, ventilated traction stays comfortable from start to finish.
The integrated Elastic Interface liner is specifically designed for gravel riding and semi-aggressive riding positions, with dual-density foam and a ventilated forefoot for long-distance support.
Two mesh cargo pockets on the back and two on the legs keep essentials close at hand, while reflective elements increase visibility in low light.
Treated with PFAS-free DWR and made from bluesign® approved materials, this bib is your go-to when the temperature drops and the miles pile up.
