      Hard-Case Lite

      Bontrager's first and lightest weight line of defense features a belt (or co-extrusion) directly under the tread, preventing glass and stone from penetrating the tread and puncturing the tube. We vary the thickness and material according to intended use, minimizing weight penalty.
