oneten Primo Bib Knickers

For optimum comfort in cooler conditions, the oneten Primo bib knicker is a three-quarter length tight offering extra warmth without performance compromise.

For road training, off-road riding and even serious commuting in colder weather, summer shorts just won’t cut the mustard when it comes to keeping you warm and dry.

Building on the great design and features of our Primo bib shorts, we’ve developed the Primo bib knicker – a three-quarter length tight designed specifically to perform in cooler conditions, with the same long-distance comfort of its warm-weather cousin.

Inspired by you

The Primo bib knicker draws on body-mapping technology for optimum regulation of heat and moisture:

  • Made from fast-drying polyester for breathability, moisture wicking and flexibility next to your skin;
  • Bib knicker features additional Roubaix fabric on thighs;
  • Rear panel features a brushed inside surface for extra warmth;
  • Front of bib straps uses open mesh fabric for additional breathability.

Comfort cut

The Primo bib knicker is cut to reflect on-bike torso positioning so it feels like a second skin, even on the longest days in the saddle. Minimal seaming with direct-print labels and logos help to avoid chafing, while two-part leg grippers – using 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.

Our specially-shaped synthetic chamois, manufactured from XP1 perforated foam, is anatomically precise and comfortable on long distances. Sculpted to ensure maximised blood flow in the saddle contact area and ventilated to allow dissipation of heat and moisture, the chamois stands up to repeated washing at high temperatures, preventing buildup of bacteria and odour.

Under the chamois a textured Lycra panel improves durability, fit and shape and provides improved grip on all saddle surfaces.

Who is it for?

We've designed the Primo bib knicker for riders of all levels and disciplines, on- and off-road, and it is the perfect companion for cool-weather training and touring; off-road riding and even autumn-to-spring commuting.

The Primo bib knicker will ensure crucial body areas stay warm, dry and pain-free on long days in the saddle, maximising comfort and circulation and minimising post-ride aches.

Use as part of a layered clothing system in conjunction with the oneten Intimo base layer, the oneten Primavera long-sleeve jersey and an outer layer such as the oneten Vento II wind jacket.
