It's a 16 ounce canvas. It is our custom material of choice and is a 20 year engineered canvas that has been under development for upwards of 10 years. It is a woven material that is woven from engineered polyester thread, not cotton. In other words, our covers are canvas, but rather than canvas constructed of cotton thread, the canvas is constructed of polyester thread.
This is our method of choice for many reasons, some of which are longevity, quality, appearance, and reliability. Think of how, for example, engineered wood flooring is many times more durable than organic wood flooring. Now, apply that thinking to our engineered canvas. The material is woven from engineered polyester thread, then polyurethaned, waterproofed, and mildew protected. The material is engineered to last at least 20 years.If you don't love it, return it, on us. Now, will this fit your frame? Just measure your bimini canvas, if there is anything left of it! If there is not anything left of it, measure your frame. This will fit any typical 4 bow frame, round or square. If your current fabric is not this exact length, it may still work, depending on if you have flexibility in your mounting points, and are willing to make your bimini slightly shorter or taller. Generally, if you have straps as opposed to poles in the front or back, you have flexibility in your mounting points. If you have support poles front and back, you probably have some flexibility. It would just be a matter of if you want to move them or not. And, this is an important point..... I f it does not fit your frame, you can return it, on us.
