CrystalCave™ Tunnel Shelters

Shelter Systems' tunnel-shaped shelter was designed for those who wish to cover a rectangular space. Crystal Caves are freestanding, sturdy, lightweight and portable. We offer two sizes (9-foot and 11-foot), and they can be placed end-to-end to produce a longer shelter, or special ordered in other lengths.

CrystalCaves have been used by imaginative customers for a variety of outdoor uses, including carports, workshops, archeological dig site covers, telescope covers and by the US Government as emergency relief shelters in Guatemala.

Durable materials
TheCovering is made Crystal Cave as carportwholly of a superstrong, tear-proof,
white multilaminate woven ripstop film which will not rot or mildew. It is UV stabilized to withstand up to 3 years full sun exposure and treated with fire retardant. The fabric is a super strong, high tensile strength, rip-stop, completely waterproof, mildew resistant, and cannot be torn by hand even after it is cut. This US made, proprietary material is the finest material we could find to make our tents from.
The Poles are of high quality US made PVC that is admirable for its strength, resiliency, long life, natural UV stability for a long sun life, and its strength to weight and cost ratio. The poles we use are Class 200 PVC tubing.
Shelter Systems' Patented Grip Clips that we use to join the domes cover to its poles are molded of a UV stabilized resin blended specifically for it high strength and durability.
