Extra durable floors (HD groundsheet) equipped with anchoring rings useful for two different purposes for owners of Titan Pro and Camo Pro. The additional HD groundsheet can be placed under the inner base chamber with PVC mesh for greater protection from gravel beds, increased damage prevention, and to avoid folding the inner capsule while still wet. Additionally, it can be used in sessions where the inner chamber is not needed but having a base tarp is still preferable. The pro groundsheets are equipped with a protective panel for the door with Velcro, which can be folded during more demanding sessions and then replaced at night to prevent the door from being torn off.
