Item # AAS0142


If there's one category in which Assos most clearly asserts its dominance in the cycling apparel market, it's with bottoms -- bib shorts and tights. After all, a short inspection of something like the T F.I.13_S5 bib shorts makes you recognize the complexity of the cut and the materials involved to make a technical piece that comfortable and that functional. And for the DB.ZERO trackPants, Assos harnesses every bit of its expertise. Meant for after the bike, or as the 'D' and the 'B' stand for -- Dopo Bici -- these bottoms provide a skillful balance of style, comfort, and functionality.

In true Assos fashion, the trackPants are made from multiple materials, with the bulk of the pants being constructed from Assos' DB.Zero fabric -- a four-way stretch that easily moves with your body while keeping the overall weight of the pants light. The waistline, the hips, crotch, and the knees are made from DB.Follow.180 fabric. This material is bi-elastic, breathable, and soft to prevent any biding to the skin as you move. Both fabrics are also highly efficient at transferring moisture.

For comfort, the trackPants use Assos' Smart Waist Design to free the abdominal area from pressure points. Not stopping there, Assos designed the pants in accordance to its Ergonomically Correct Pattern Design. This means that every stitch, every panel, is purposefully placed to complement the movements of cycling. Additionally, the right lower-leg features a zipper that can be opened for easy cuff rolling before you roll out to fetch your morning coffee.

Knowing that these are post-ride pants, Assos incorporated a series of zippered pockets and flaps for both comfort and functionality. There are two front hand pockets, the aforementioned leg zipper, and a front mini zipper.

The Assos DB.ZERO trackPants are available in six sizes from X-Small to TIR and in the color Black.
