Which should I pick and why?
No order minimum. Choose this option to send fabric cut and folded (like a blanket). See continuous cut policy for full details on max cut lengths.
  • 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).

Fear not!

I was a bit intimidated to use this material, coated lightweight fabrics are notoriously difficult to work with. However, this material is a diamond in the rough, very easy to handle for all your MYOG projects. It’s slightly stiff, which makes laying out and marking up easy. I had no issue feeding the material through my sewing machine, didn’t even need to do the “tissue trick” to prevent slipping. Looking forward to using this material on future projects!

1.1 Silpoly PU 4000

Using this to make a bathtub floor for a tent. Looks and feels very sturdy consider how lightweight it is. I was hoping I wouldn’t need a groundsheet and after feeling this, I’m happy to say I’m not going to need one. This is very easy to work with and sew. Great service as always!

Silpoly pu4000

I used it to make a frame bag for my fatbike. Easy enough to work with. Not sure what the durability will be like, I imagine it'll take quite a bit of abuse. But for the price, it's worth the test! Great customer service and shipping speed, as usual!

Hi Cam! Thanks for the review! The 1.1 Silpoly PU4000 is a great material. Good luck with the frame bag!
