Tweedster Fabric. 70% Polyester, 26% Rayon, 4% Spandex, Yarn-dyed, textured outer fabric. Bonded to 100% Polyester durable mesh interior. DWR (durable water resistance) treated. 8,000mm; 3,000g/m2 (waterproof/breathability). Hard-wearing and great looking, Tweedster fabric has a textured outer face for style but takes a beating and shrugs off water thanks to the Dupont Teflon Shield+ DWR treatment and waterproof membrane. Certainly the burliest shorts in the Race Face collection, the Ambush Short is recommended for aggressive riding when extra abrasion resistance and durability is preferred. 3D mesh paneling enhances air flow. Raised back panel ensures no builder's bum. Inseam is 38cm (15in), under knee, with hem openings large enough to accommodate Race Face pads.
