Rectangular Shade Sail, Black HDPE UV Block Sun Shade Cloth for Patio, Deck, Backyard, Balcony, Pergola & Carport Canopy | Lonoma

Cool, Comfortable Shade for Your Outdoor Space

Turn a blazing patio into a spot you actually want to sit in. This rectangular shade sail is made from high-density polyethylene (HDPE) with an open, breathable weave that blocks 85–90% of sunlight while letting warm air drift through instead of trapping it underneath. You get a noticeably cooler seating area without the stuffy, closed-in feeling of a solid tarp. The built-in UV-resistant treatment helps protect your outdoor furniture, deck, and the fabric itself from fading and early wear, so your backyard, balcony, or patio stays inviting all summer long.
