Type.441 is a gently compressive, silky smooth material that feels more abrasion-resistant than your typical bib short material because it is. It also actively cools while protecting against UV rays and resisting odor.

A-Lock Engineering is our S9 racingFit realized for bib shorts, with every fabric panel, strap, and stitch engineered for stability and confident comfort. ASSOS shorts are legendary; this fit design is why.

Butterfly Pattern: The main textile panel wraps the lower back and legs, reducing seams and providing a more uniform compression across the shorts’ body.

Carbon Xbib: An A-frame bib that limits vertical stretch in the rear. The straps lie flat over the shoulders to eliminate sub-jersey bulk and curve outward in a female-specific design.

Ultralight Leg Grippers: The leg bands feature a silicone treatment woven through the bands themselves, creating a secure hold without restriction or lumpy transitional ridges.

DYORA RS Insert: Antibacterial microfiber booster top sheet in 3D basalt colorway. Pays homage to the lava stone that gives us strength, stability, and courage.

goldenGate: A stitching pattern that anchors the front and back but lets the insert’s body float, allowing the insert to move with your body rather than against it.

superAir microShock foam: A light, shock-absorbing foam that springs back to its original shape, filling the gaps that open and close between body and chamois during the pedal stroke.

Surface Reduction Design: Insert footprint reduced from previous UMA pattern to shed extra grams; microfiber topsheet retains antibacterial properties in the new 3D basalt colorway.
