Sport-Brella Versa-Brella SPF 50+ Adjustable Umbrella with Universal Clamp

The Sport-Brella is a clamp-on umbrella designed to provide shade and limited rain protection for outdoor activities. It can attach to lawn chairs and camping-style chairs, but not all types of chairs, so it is recommended to check the chair design before purchasing. The pole is not circular, instead it is kite shaped, with dimensions of 33 inches long, 21 inches on each side, 16 inches from the front edge, and 26 inches from the back edge. The clamp is designed to fit a round tube like regular aluminum tubular frame folding lawn chairs. It is also versatile, with the ability to adjust to block the direction the sun is coming from. Although it is water-resistant, it cannot provide complete protection from rain, and its size is limited. The XL size is larger than the regular size, measuring 44 inches compared to the regular size's 39 inches. The clamp is sturdy and secure, but it is not recommended for use on chairs with limited supports, as gusts of wind can easily turn the umbrella inside out. Overall, the Sport-Brella is a useful tool for keeping cool and shaded during outdoor activities, although check compatibility with the chair and the wind conditions before purchasing.
