For long hours in the saddle, under any short there's no better feeling against your skin than a Fox ProForm Short Liner. Breathable stretch fabric follows your bodyline and holds the Pro-Form M Chamois in place for ultimate comfort and performance. These liners are so good in fact; that you could wear them as shorts on their own - with all of the featrures you'd expect from a high end short such as quality comfortable materials, silicon leg gripper and comfortable waist-band.
