AEPD cut (Assos Advanced Ergonomic Pattern Design), it is made out of Roubaix material and incorporates Assos' new Lycra blend Type A.360 in the thigh and buttock zone. This to improve fitting and reduce fabric piling. Features FI Mille elastic interface insert. The new Assos Knicker is simply spectacular from a technical as well as aesthetical point of view. Another Assos masterpiece.
