  • Placing a wholesale order shouldn't  be hard, so we made it easy...

    For the first time, order   full rolls of material  straight through the site. No emails, invoices, or wasted time. And did we mention wholesale pricing? 

    IMPORTANT  - Discount codes are   not allowed  for any wholesale purchase. If you use a discount code, the portion applied to any wholesale line item will be added back to the shipping invoice we send you. 

    NOTE - This is a   full roll  of 1.1 oz Silpoly PU4000 (125 yds). Looking for smaller amounts? Click   HERE for sales by the yard. 


    This is the high water-resistance version of our  2nd generation 1.1 oz Silpoly line of coated materials. This fabric is coated with a silicone/PU layer on one side, then a multi-pass PU coating on the other to create a highly waterproof/non-breathable fabric.

    Same silpoly benefits of   lower water absorptionand   increased UV resistance, but with a much  higher waterproof rating. The PU4000 also has less bias stretch, making it easier to sew.

    Great for projects such as tent/shelter floors, ground sheets, tarps, ponchos, gear sacks, pack covers, or any application where lightweight, highly waterproof/windproof fabric is needed.

    *Note - shiny side is PU4000 and dull is sil/PU. If seam sealing this fabric, you will need a sealant intended for PU coated materials (e.g. Seam Grip).

1.1oz Silpoly for ground cover

This strong fabric is great for a durable ground cover. Highly recommended.

Hi David, Thanks for the review. The PU4000 is perfect for ground contact applications.

Great experience

I needed a waterproof fabric for a simple project. I wanted to layer the waterproof fabric with a piece of regular fabric store fleece to make a rainproof blanket for use at my grandsons' grade school football and soccer games. I received a quick response to my email asking if the fabric would be appropriate. I ordered silypoly pu4000 as recommended. The fabric arrived quickly. It was exactly as expected and the color was true to the website. The blankets turned out great. The PU4000 slid less than expected with some well placed pinning making it easy to create a "binding" over the edge of the fleece and to the stitch the layers together. The blankets look great. But, because this is Ohio, we have had no rain and temperatures in the high 80s to 90s recently so I have yet to actually test the blankets. Maybe this weekend. Great company and product. I would happily do business with RipStop again.

Hi Debbie, I'm glad we were able to help you find the right material. Thanks for the review

Great product

Very easy to work with. This was for my first MYOG project and my first time using a sewing machine. Used it for my tent's doors and roof. Its very waterproof after I made my tent I tested the seam sealing spraying it with a garden hose and not a drop came inside.

SilPoly PU400

Though this material is very waterproof, it rips extremely easily and then doesn't stop, so small holes turn into giant rips. I was planning on using it for a tent floor (as it is recommended on the FAQ, however I found the 1.1 SilPoly without coating to be much more durable) but decided to stop the project because not only would the floor rip, but the other material I ordered for the rain fly was the wrong color. With that being said, I will be able to find another use for these materials (though they are already cut) and I am confident that it's waterproofing will last. I would have given two stars but I think RSBTR is usually very reliable and helpful, even though this time I don't think their recommendation of this for a tent floor was good.

I love this stuff for tent floors. It feels more robust than the non PU4000 silpoly, but still super light.
