Biotex Seamless Ultra Black Boxer Underwear

Technical boxer with integrated AirProMax 8H+ pad, ideal for bike rides of more than 8 hours. Seamless construction, recycled fabric, total comfort and zero movement in the saddle.

The Seamless ULTRA Boxer with chamois is the perfect choice for those who tackle long distances on the bike. Designed to be worn under any short, directly in contact with the skin, without underwear, it combines performance and comfort thanks to the seamless construction, the snug fit and the AirProMax 8H+ chamois.

The stretch fabric made of recycled polyamide with a "zero waste" structure adapts to the body like a second skin, ensuring maximum freedom of movement and stability even on the longest rides. The HTS (Humidity Transition System) allows for rapid sweat evacuation, keeping the skin dry and cool.

The three-layer AirProMax 8H+ chamois, made of open-cell foams and covered in fabric with Bamboo fibers, offers support and breathability even beyond 8 hours in the saddle. The leg (+ long compared to the seamless boxer with chamois) and the high waistband prevent any movement, ensuring a hold comparable to a bib short, but with the freedom of a boxer.

Perfect to wear under any trousers or shorts, the Boxer ULTRA is the invisible and ultra-performing solution for Gravel, MTB and cycle touring.

How: Wear it directly against the skin, without underwear. Perfect under technical trousers, long or short.

When: ideal in all seasons for Gravel, MTB and cycle touring rides, even over 8 hours in the saddle. It is at its best on long distances and bike trips.
