Upper body and sleeves use the woven textiles previously restricted to a handful of WorldTour riders. Lower skin friction and cleaner airflow than the knitted fabrics they replace.
Three standard rear pockets. Laser-cut sleeves and hem with internal silicone print. No flutter, no slip.
Race fit, borrowing cutting patterns from our TT suits for second skin fit, high waist line to reduce bunching. Stays smooth whether you’re on the hoods or pushing hard in the drops.
Pair with Obsidian Bib Shorts to complete the look.
Usage

Built for riders chasing elite aerodynamics in every scenario. Pairing wind-tunnel optimised panel layouts, state of the art R&D, and custom-made fabrics.  A package that provides World Tour-grade performance, ready to wearand race.

Wear it for high-velocity training, decisive efforts, and race days where optimal aero matters as much as power.

Surpassed in performance only by our Neo collection.

World Tour Tech
Based on our One TT Suit which over a flat 10-mile TT, at 50 kph, a saving of 6.45 W would save our test rider over 5.21 seconds compared to our previous single layer skinsuit. Put another way, as this rider crossed the line in the One TT Suit, the same rider in our previous suit would be 72.3m or 237.3ft behind.
