This cover is part of the Budge Industries NeverWet Savanna collection. Styled to compliment your patio décor, this collection comes in an attractive sandy-tan color. The NeverWet Savanna collection combines long-lasting durability of machine-woven 600 denier polyester with groundbreaking Rust-Oleum NeverWet technology and UV protection. With NeverWet technology, water rolls right off the cover, taking mud, tree-sap, dirt, and bird droppings with it. The easy-adjust lock-cord hem helps weatherproof the hot tub by providing a tighter grip around the base. How to Measure: This cover is designed to fit over the cap of a square hot tub. In order to make sure that you get the correct size, please follow these simple instructions. Measure the length and width of the hot tub; since this cover is for a square hot tub, these measurements are the same. Measure the height of the hot tub’s heat resistant cover; this is a straight line from the top edge of the cover to the bottom. The cover comes with a shock-cord hem which will keep the cover secure in windy and stormy conditions.
