With the S9, Assos spent 6 years developing materials and construction methods, and testing them on the world’s most demanding athletes.
The basis of the garment is A-LOCK Engineering, a patented framework of textiles and technologies.
The result is a new level of stability, to complement the comfort and fit Assos is famous for.
Side panel construction is completely stitch free, comprised of highly compressive, durable and superlight fabric. The straps fit flat against the small of the back, and feature an antibacterial carbon weave.
Noticeable stability. Rather than stopping at the waist, the straps extend all the way down to the chamois - which is integrated with the garment using square panel construction. This system acts to secure the chamois and add noticeable stability in cornering and out of the saddle.
Natural feel. The front and rear of the chamois are sewn in place while the middle floats freely in response with your body’s movements.
Superior comfort. A 3D waffle shaped composition - allowing increased airflow and cooling. The foam is designed to effectively absorb the kind of micro shocks that come with road riding.
