The sail's standout attribute is its measured sun-blocking performance, made possible by the 200 GSM HDPE fabric that claims up to \u003cstrong\u003e95% sun protection\u003c\/strong\u003e. Installation is flexible enough for DIYers who can anchor to trees, posts, roofs, or walls, and the unit ships as a made-to-measure canopy that aims to fit exactly from D-ring to D-ring.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n\u003cstrong\u003e95% UV blockage:\u003c\/strong\u003e The 200 GSM HDPE fabric blocks up to 95% of harmful UV rays, providing a much safer shaded area for extended outdoor use.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eTemperature reduction:\u003c\/strong\u003e The sail can lower ambient temperatures under the canopy by up to 15 degrees compared with unshaded space, making it noticeably cooler on hot days.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eCustom sizing:\u003c\/strong\u003e Measurements are taken D-ring to D-ring so the sail is tailored to the space and can be adjusted if straight edges are preferred.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eDurable construction:\u003c\/strong\u003e Reinforced edges, double-layer stitching and stainless steel D-rings increase longevity and reduce fraying at attachment points.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eBreathable and water permeable:\u003c\/strong\u003e The HDPE weave is air and water permeable so it reduces heat buildup and sheds water rather than pooling.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eFlexible installation:\u003c\/strong\u003e Can be mounted to trees, walls, roofs or poles and works with common mounting hardware kits for varied site conditions.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis shade sail is ideal for homeowners with patios, decks or play areas who want a precise, large-format shade solution rather than an umbrella or pergola.

Customers who cannot perform a careful D-ring to D-ring measurement or lack sturdy anchor points should consider a different shade system.\u003c\/p\u003e\n\n\u003ch2\u003ePros \u0026amp; Cons\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003ePros\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n \u003cli\u003eHigh sun protection with the 200 GSM material blocking up to 95% of UV rays.\u003c\/li\u003e\n \u003cli\u003eCustom sizing provides a better fit and cleaner look than off-the-shelf sails.\u003c\/li\u003e\n \u003cli\u003eStainless steel D-rings and reinforced, double-stitched edges improve strength at stress points.\u003c\/li\u003e\n \u003cli\u003eInstallation is flexible and works with common mounting hardware for multiple mounting options.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eCons\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n \u003cli\u003eDurability feedback is mixed; while many report solid multi-year use, some note faster degradation in harsh sun exposure.\u003c\/li\u003e\n \u003cli\u003eNot fully waterproof-designed to be water permeable, so it does not provide complete rain protection.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n \u003ctr\u003e\n\u003ctd\u003eShape\u003c\/td\u003e\n\u003ctd\u003eRight triangle\u003c\/td\u003e\n\u003c\/tr\u003e\n \u003ctr\u003e\n\u003ctd\u003eSize (D-ring to D-ring)\u003c\/td\u003e\n\u003ctd\u003e16' x 21' x 26.4'\u003c\/td\u003e\n\u003c\/tr\u003e\n \u003ctr\u003e\n\u003ctd\u003eColor\u003c\/td\u003e\n\u003ctd\u003eBlue\u003c\/td\u003e\n\u003c\/tr\u003e\n \u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003e200 GSM HDPE\u003c\/td\u003e\n\u003c\/tr\u003e\n \u003ctr\u003e\n\u003ctd\u003eUV Protection\u003c\/td\u003e\n\u003ctd\u003eUp to 95% blockage (UPF50+)\u003c\/td\u003e\n\u003c\/tr\u003e\n \u003ctr\u003e\n\u003ctd\u003eEdge \u0026amp; fittings\u003c\/td\u003e\n\u003ctd\u003eReinforced edges, stainless steel D-rings, double-layer stitching\u003c\/td\u003e\n\u003c\/tr\u003e\n \u003ctr\u003e\n\u003ctd\u003eWeather\u003c\/td\u003e\n\u003ctd\u003eWater and air permeable, reduces temperature up to 15 degrees\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eOur Verdict\u003c\/h2\u003e\n\u003cp\u003eThe custom 16' x 21' x 26.4' blue right triangle shade sail is a solid value for anyone who needs targeted, high-UV protection and a tailored fit without building permanent structures.
