The Suncave shelter is a ground-level structure that offers protection against sun, wind, and rain for a small family or up to four adults. It can be easily transported, quickly deployed, and easily stowed for transferring between outside activities. This makes it a terrific choice for active families or groups of friends at the beach or day-use outdoor recreation facilities, as well as sideline supporters spending several hours at the sports field. While the Suncave shelter is designed with a floor-to-ceiling opening for easy ingress and egress, it also includes a permanently affixed floor extension that not only serves as a ground cover for enhancing seating capabilities in front of the shelter, but can also be lifted and attached to the sides of the structure’s opening with the attached hook-and-loop fasteners to create a temporary private space. The Suncave shelter also features mesh-covered windows for optional ventilation, as well as stash pockets for securely stowing small items. Combining the benefits of a fixed-pole tent-like structure with the easy operation of Sport-Brella’s renowned umbrella-based shade structures, the Suncave shelter offers a unique approach to fulfilling Sport-Brella’s mission of developing intuitive elemental shelters that empower families and friends to gather outside together.
