We are Cypress Rowe Outfitters. Our mission is to make your outdoor experience better. We took our classic original cover and made it better. We made it nature proof and supercharged it for outdoor storage. The material is a woven canvas, but the threads from which it is woven are polyester. Covered vs uncovered is a no-brainer. The purpose of this cover is threefold. One is to cover and protect your investment. Covered vs uncovered is night and day. The value of a good cover is intrinsically obvious each time you uncover your vessel. Just in the spring when you break it out for the first time and do not spend half a day cleaning leaves and spider webs out of it, a good cover earns its keep! The second purpose of this cover is to provide you with a cover that will not be lying shredded in your yard next year. The third is to help the environment just a tad. We do this by not offering cheaply made covers that end up unusable and in your local landfill. We proudly offer a lifetime warranty. Here is what you want…Cover to protect and keep clean your investment while not buying a new cover every year because your previous purchase is deteriorated to dust held together by weak deteriorated strands of weathered material…… Our covers are not just waterproof, but Nature Proof. Our canoe/kayak covers are engineered to protect against water, the sun, tree residue(sap and leaves and stains), etc. Our covers can be used and secured in multiple ways, based on your specific circumstances. They come with a hidden bungee style cord in the hem, for a quick on and off cover. Now, if you want to kick it up a notch, in the front, this hidden bungee style cord has an adjustor, so you can customize the fit. They also have built in straps. Lifetime warranty if you love it, free returns if you don't…
