The Vevor boat bimini top cover is built with heavy-duty 600D marine-grade polyester and a lightweight aluminum alloy frame for reliable shade and weather protection on the water. Its 3-bow design offers stable coverage for boats with deck widths from 54" to 60". The canopy is designed to resist sun exposure, water, and winds up to 45 MPH while folding easily for storage when not in use. It also includes support poles, adjustable straps, and a storage bag for convenient installation and transport.
