Tights don't get more technically advanced than the Assos Bonka EVO Bib Tight.

Offering incredible warmth and protection from the blend of performance fabrics, CENTO S7 EVO seat pad and racingFit.

Assos Bonka EVO Bib Tight

You needn't retreat onto the turbo come the middle of winter, this Assos Bonka EVO Bib Tight makes the harshest conditions more comfortable and is packed with advanced technology. Insulation is targeted to take into account of where the cold hits hardest, and Assos have utilised RX Heavy to the front of the legs, additionally layered with windproof Stratagon Ultra on the knees, hips and thighs. In less exposed areas RX Light features and the combination brings insulation, breathability, moisture-wicking and flex. A DWR treatment adds another barrier to the rain. Additionally, Assos have included a more breathable wind and waterproof panel over the abdomen and crotch, plus waterBarrier at the bottom of the leg.

A CENTO S7 EVO and 3D waffle seat pad feature 10mm of memory foam, perforations for ventilation and it'll move with you as you pedal. Unique to Assos, the kukuPenthouse microfibre layer at the front of the chamois supports the male anatomy and relieves excess pressure. The bib straps are smooth, light and stretchy, stabilised by a Y-shaped back section, and the tight has been finished with reflective bands for extra safety.


  • 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. ECO water-repellent / odorControl
  • Stratagon Ultra: A patented 2L windproof and highly breathable softshell constructed with a PU bonded membrane for added water-repellency that maximises insulation while minimising bulk. Four-way stretch. Used as an additional layer on the knee, hip, and thigh areas
  • blasenSchutz: An abdomen and crotch panel made with highly breathable, wind- and waterproof Stratagon Ultra material to increase comfort and warmth
  • RX Light: Lightweight, asymmetrical-stretch warp-knit fabric developed to provide light insulation and boost comfort in high-flex areas. ECO water-repellent / odorControl
  • DWR: Treated with a Durable Water Repellent treatment to add one more level of insurance against the elements
  • waterBarrier: 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 colourway, and 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 microfibre 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
  • Stabilizator V3: Dorsal stabiliser in a solid mesh with limited vertical stretch
  • Reflective bands: Placed on the backs of the calves for added visibility
  • racingFit: A fit that is tighter and slightly more compressive than the 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
