The Essential Thermal Long Bib are packed with innovative fabric technology. These long bibs feature the renowned M.I.T.I. SuperRoubaix fleece with a DWR treatment and an anti-abrasive finish for excellent water-repellent capabilities and increased durability. The heavier, brushed fleece surface provides exceptional insulation but is not too thick to restrict mobility. The raw edges of the straps keep the bibs flat against your body, and a soft mesh backing makes this piece highly breathable.
