Her' Chamois Butt'r was formulated by a female sports medicine physician to specifically cater to female cyclists. Like all Chamois Butt'r products it uses natural ingredients to make a non-greasy skin lubricant, and a conditioner for synthetic or leather chamois that improves riding comfort immediately and will soothe and soften already chafed or irritated skin. Designed with women specifically in mind, this product is safe for both sexes. Her' Chamois Butt'r is available in an 8oz tube.
