oneten Primo II Bib Shorts

The improved oneten Primo II bib short fits like a glove and performs like a champion, keeping you cool and comfortable on even the most epic of rides.

A punishing training schedule, a packed competitive calendar or a simple love of epic Sunday spins – long hours in the saddle demand clothing that can rise to the challenge and meet the needs of your body.

Building on the oneten Primo bib shorts we introduce the Primo II, offering the same great fit as the original Primo with new and improved features.

Inspired by you

Body-mapping technology means we use different types of fabric in the areas where they will be most effective:

  • Bib front and legs: The upper bib and legs are manufactured from a blend of 220g polyester and Lycra offering the perfect balance of flexibility, fit and moisture wicking capability next to your skin.
  • Rear: A 3D-structured open mesh panel at the back enables internal air flow, allowing moisture to evaporate and heat to escape. Our unique one-way stretch technology means the fabric will only stretch horizontally in order to prevent sagging.
  • Two-part leg grippers: Light silicone tape on back of leg and stretch Lycra panels on front adapt to a variety of rider leg shapes to prevent the garment legs from riding up without causing pressure or irritation.

Comfort cut

The Primo II bib short is cut to reflect on-bike torso positioning so it feels like a second skin, even on the longest days in the saddle. Leg panels have been designed with the specifics of cycling morphology – muscle development – in mind, with ultimate flexibility to handle the constant repetition of pedalling movement without chafing.

In addition, minimal seaming and direct-print internal labels enhance the 'second skin' sensation while new custom reflective tabs improve low-light visibility and a faster-drying textured centre panel offers improved grip on all saddle surfaces.

Finally – but crucially – we've provided a specially-shaped synthetic chamois manufactured from XP1 perforated foam. Anatomically precise and comfortable on long distances, the chamois is specially sculpted to ensure maximised blood flow in the saddle contact area and ventilated to allow dissipation of heat and moisture. Additional durability and heat resistance means the chamois stands up to repeated washing at high temperatures, preventing building of bacteria and odour.

Who is it for?

We've designed the Primo II bib short for riders of all levels and disciplines, on- and off-road, and it is the perfect companion for year-round training and touring; Sportif- and Audax-style events; club racing; triathlons and XC mtb.

Used as part of a layered clothing system it will make sure crucial body areas stay warm, dry and pain-free on long days in the saddle, maximising comfort and circulation and minimising post-ride aches.
