This is a Lighter weighted version of the Poly Pro Extreme. The  Polyester fibers still start out as a liquid acrylic polymer solution. When piece-dyed or “stock” fabrics are made, the fibers are dipped into a vat of dye. Only the outer surface of the fibers are colored; the interior of each fiber remains white. The method produces a great color, and it allows manufacturers to create smaller batches of fabric using less dye. Most synthetic fibers are dyed this way. 
Solution-dyed fibers are colored in an entirely different way. The dye is added to the chemical solution before the individual fibers are even made. This means that the dye is completely mixed into each fiber.. The color doesn’t just sit on the surface; it goes all the way through the fiber.
The Fibers are a top grade Polyester using a coated Technology. These top quality expanded acrylic fibers are coated with a high grade solution that prevents degrading and are made to last outside, be tow-able and or withstand high winds and or the corrosive nature of the outdoor elements.
 
is a Great Material. Its a decent weighted solution dyed canvas that lasts much longer, not just in strength but in color as well. The individual fibers are stronger than traditional canvas materials. This material is made NOT to disappoint.
