  • The 2nd generation of our silicone double coated 1.1 oz polyester ripstop (silpoly). This fabric is coated with a silicone/PU layer on each side and is waterproof/non-breathable.

    In addition to excellent waterproof/windproof characteristics, Silpoly offers lower water absorption and increased UV resistance compared to Silnylon. Particularly useful in outdoor applications to minimize sag/stretch when wet and color fade over time.

    Great for projects such as tarps, tents, ponchos, gear sacks, pack covers, or any application where durable waterproof/windproof fabric is needed.

    NOTE  - Colors with a reduced price of $4.75 /yd are being  phased out of inventory . Once sold out, they  will not be restocked

The tarp kit is great for anyone just starting to sew their own gear. The kit provides ample material to make any size rainfly you want with enough left over for its own stuff sack. I made mine with an 11 ft. ridgeline and cat cuts on all sides. Make no mistake, the material is very slippery, so be sure to double check all lines before cutting as the material has a tendency to slide on itself. My only complaint is with the tie-out reinforcements. The pieces are now pre-cut, but are not as large as I was expecting which made it difficult to attach them as shown in the directions. Overall, a great product. My next adventure will be the winter version of the kit.

Hi Ryan, Thanks for the review! We look forward to helping you in the future!

I purchased some 2nds quality silpoly in the past, and was disappointed by the feel. This recent purchase is soft/supple, and feels wonderful! Made it into a tarp and has had one night of rain, in which I stayed dry (except through my unsealed ridgeline)

Hi Owen, The new Silpoly is a great material. A little Silnet on that ridgeline will help keep you dry!
Great Product

This stuff is excellent. I've been using it most recently to make some top-zip bags. Stops water, easy to work with, lightweight, and super vibrant colors. What more could i ask for!?

Hi Banks, The 1.1 Silpoly is the perfect material for waterproof bags. Thanks for the review!

This fabric is soft and very usable. It is also the choice of most of my customers. They like the finish and feel as well as the large choice of colors.

As always Ripstop by the Roll was fast and accurate processing the order, even getting it to me a few days faster then expected.

Thanks for the review! We strive to get orders to you as quickly as possible.

Transaction and delivery were good. I bought a tarp kit because the total bill of materials cost less than if I had bought parts separately. There were several options on the shape of the tarp, I made it shorter than the instructions, and the hardware kit was for a winter tarp, so I have d rings and reinforcement patches left over, as well as plenty of material for extra projects. The thing I did not like was that the instructions did not match the supplies, e.g. reinforcement patches supplied were not the same shape as on the instructions. There were also construction details on the instructions that seemed to conflict with each other and were unclear. I ended up just looking at another tarp I have and making it like that.

The material was generally easy to work with except when trying to do a hem on the bias. It just would not roll under without twisting. A characteristic of the stiffness and slipperiness of the material. Pinning really did not work in those areas. Perhaps ironing the seam over before sewing would be better. I just sewed the first fold separately, then the second fold, instead of both at once (to make a rolled hem). It ended up with some angle wrinkles, but I did not care enough about the looks to do it differently.

Hi Edward, Thanks for the review, as well the as the feedback on the instructions. We'll see what we can do to streamline those instructions, and update them with the new laser cut reinforcements.
