The Assos TRAIL Liner Bib Knickers bring you the same benefits as their mountain bike liner shorts, namely extra storage and superb on-the-saddle comfort, and with the extra length, they keep your knees cosy in cooler weather.

Worn under Assos' own cargo shorts or your own personal favourite MTB baggies, the TRAIL Liner Bib Knickers bring extra comfort to your dirt-riding. In order to make them barely noticeable once you pull them on, Assos deploy their super-flexible bib straps to the upper. These lie perfectly flat and provide support for the lower body. A Stabilizator mesh panel across the back ensures perfect temperature regulation and breathability when you're putting pressure on the pedals. Meanwhile, a new waist construction, AZPtech (abdomZeroPressure), keeps the tights firmly held in place but does so with minimal pressure, letting you move and breathe easily. 

When it comes to the legs, Assos uses their Aerofit fabric. Highly flexible, ultrasoft and breathable, this open-structure material ensures you stay cool as things heat up. Push-Pull panels across the waist, lower back and back of the knees provides light and airy comfort too. And raw-cut finishes around the waist and at the leg hems give a smooth, streamlined fit. 

If you like to wear a loose-fitting mountain bike top then the Trail bibs provide easy-access storage space by way of their two rear cargo pockets. These pockets sit comfortably above the waistband and allow easy access to your essentials under your jersey. Ride light. Ride easy. Always have essentials to hand. 

OFF-ROAD Liner EVO Seat Pad

On the saddle, the OFF-ROAD Liner EVO Insert is designed to offer extra support across the rear of the pad, suited to the more upright riding position when mountain biking. The 3D waffle construction sees three-layers of perforated foam delivering impressive breathability while reducing bulk. Ventilation is also optimised due to the kraterCooler system, whereby perforation holes along the front of the pad increase airflow and cool your sensitive areas.

About the Assos brand

Assos are one of the world's pioneers and specialists in producing high quality cycling clothes and accessories. They are located in a region of Switzerland that has maintained a long standing tradition in first class textile engineering. In the 1970's, Toni Maier-Moussa, founder and chairman of Assos accidently invented lycra cycling clothing, whilst trying to create the ultimate bicycle. During the wind tunnel tests of the first ever carbon-fibre bike, Toni inadvertently found that lycra downhill ski racing suits had much less drag than the woolen-knitted cycling clothes of the time. To this day Assos firmly believe in total product competence, delivering optimum function and comfort, by researching and making its cycling clothing and accessories from the very best materials.
