Bigger isn’t always better, but with the ProFlyXL Sil it’s perfect. We have taken our most popular tarp design and amplified it for maximum protection. This sleek and versatile rain cover will keep the elements away in every season. The streamlined rectangular shape and six guy points allow for a large footprint and effective shelter from sudden downpours to blazing sun, and everything in between. Now in lightweight and extremely weatherproof sil nylon.
