The mobile launcher of performance eyewear is a lightweight shell of reinforced nylon. The small Soft Vault protects Minute, Fives, Wires or Eye Jackets (although we've heard that the large case may be better for the Oakley Eye Jacket 2.0). The larger Soft Vault can hold Straight Jackets, Trenchcoats, Topcoats, Frogskins or Tens.
