The Bonka has evolved, now constructed with an arsenal of proven winter-proof textiles and our CENTO EVO insert to deliver unmatched levels of insulation, protection, and long-distance comfort. With double-layer protection throughout, these stand in as our most protective bib tights.

 

For the most demanding winter conditions that relegate all but the most dedicated riders back indoors, the Bonkas are purpose-built to thrive. We began with the same highly insulating brushed-back RX Heavy that’s used in our Winter Bib Tights, but we applied a double-layer construction with our acclaimed 2L Stratagon Ultra around the knees, hips, and thighs for added protection, ensuring the front half of your lower body remains fully protected from sleet, road spray, biting winds, and low temperatures. As with the Winter Bib Tights, RX Light makes up the backs of the legs for added breathability in this high-flex region.

 

The fit of the Bonkas falls into our racingFit category, which means they’re moderately compressive with their double-layer design. The fabric panels flex with each pedal stroke, as they’re both pre-shaped and sewn to fully wrap and support the upper leg muscles, knees, and calves while in motion. The insert is our CENTO EVO, featuring 10mm of plush memory foam for dependable comfort on every ride.

RX Heavy: A brushed warp-knit fabric that has been developed to provide exceptional comfort, wick moisture, add high levels of insulation, and remain extremely flexible. 290g/m2, ECO water-repellent, and odorControl.

Stratagon Ultra:A patented 2L windproof and highly breathable softshell constructed with a PU bonded membrane for added water-repellency that maximizes insulation while minimizing bulk.Weight: 150g/m2 Breathability: MVP 19,000g/m2/24h; Water Column: >10,000mm; Elasticity: 4-way stretch.Used as an additional layer on the knee, hip, and thigh areas.

RX Light: Lightweight, asymmetrical-stretch warp-knit fabric developed to provide light insulation and boost comfort in high-flex areas. 205g/m2, ECO water-repellent, and odorControl.

DWR: Treated with our Durable Water Repellent treatment to add one more level of insurance against the elements.

waterBarrier: Our Geoprene outermost layer at the bottom of the leg that repels water and adheres to booties.

CENTO S7 EVO: The CENTO elastic interface insert, evolved. New black colorway, and our proven 10mm of memory foam, this insert is nestled at the intersection between comfort and performance.

3D waffle: A patented, three-layer perforated foam that increases breathability and eliminates excess weight.

goldenGate: A patented technology that interrupts the stitching along both of the insert's side panels, allowing a more three-dimensional freedom of movement in this sensitive, rotational area.

kukuPenthouse: A soft, brushed microfiber layer added to the front part of the insert that supports the male anatomy, eliminates pressure, and increases ventilation.

Y7 Frame Carrier Bib Tech: Wide, flexible bib straps converge at the upper back in a Y-shape design, resulting in a flat, stable structure that disappears between the shoulder blades.

StabilizatorV3: Dorsal stabilizer in a solid mesh with limited vertical stretch. Includes updated line graphics and climaCode.


Reflective Bands: Placed on the backs of the calves for added visibility.

racingFit: A fit that is tighter and slightly more compressive than our alternative regularFit and comfortFit options. It may feel restrictive out of the riding position but feels like a second skin while riding, resulting in improved comfort and less drag.
