The choice of materials, the design of this chamois, and how it is inserted into the bib shorts make it one of the best. Several layers are sandwiched together. Softness: the top layer to the chamois (that touches the skin) is made from a soft antibacterial microfiber fabric. This material is anti-bacterial and has good wicking and breathing properties. Shape & Design: Anatomic cut helps reduce any bulk and bunching. Varying thicknesses of Foam help relieve pressure in the right places. Its unique design limits the pressure on the prostatic area.Absence of seams: No irritating seams where the chamois touches the skin.
