Fabrics Coming to the Shop (Updated August 23)

I will be offering high strength 210D nylon-66 with a thin polyurethane (PU) coating on one side and a thicker, heat sealable polyurethane (TPU) coating on the other side (see Fabrics for definitions), and also a lighter weight 40D (320T) nylon-66, also with TPU and PU coatings.

Nylon-66 is the stronger form of nylon, used in things like parachutes, airbags, and military applications, and it has a significantly higher melting point than regular nylon-6, so you are much less likely to damage it with a heat sealing iron.

I haven’t figured out exact prices yet, but they will be lower than the alternative fabrics available elsewhere (even though there are no other fabrics as good as this available anywhere online).

As I’ve written before, I’m in this for the fun of it, not to get rich, so offering the highest quality products at the lowest price will always be my top priority.

  1. Your original raft, with a 3 oz per square yard (osy) fabric, weighed 1.79 pounds.
    The yellow raft weighed 1.41 pounds — a lighter fabric.
    The new fabric is about 6 osy implying a 3.5 pound boat.

    The yellow fabric sounds more interesting — maybe with the heavier fabric for the floor. Are you planning to offer the lighter fabric or something similarly light?

    1. Hi Steve,

      I am planning to offer a lighter fabric, and a heavier one as well at some point down the road (for even tougher floors). I may be able to get the lighter fabric with the first shipment, but I’m not sure yet. I will update this post with new details as they come.


      1. Fabrics just came in today. Your plans arrived even earlier than expected (less than two weeks, and I am not even in living in some central area of Italy). They seem a little too thin to my newbie eye. Is there a minimum thickness for the TPU coating needed to withstand airpressure? On http://www.extremtextil.de/catalog/advanced_search_result.php?keywords=tpu+film&x=0&y=0 I saw they offer two kind of tpu film 0,06mm (80g/sq) and 0,3mm (340g/sq) . I don’t know if that is the film they apply to the fabric, but I wanted to ask them before start cutting and sealing for the packraft! Would it be good if the tpu was 0,06 or 0,3 mm ?

        1. I’m glad the plans arrived quickly!

          I have tried fabrics with TPU coatings between 0.04 mm and 0.15 mm, and all have held air, but the ideal thickness will depend on the denier and thread count of the fabric; 0.06 would feel thin and 0.3 mm would feel very thick and heavy. Based on the advertised weight of that 210D nylon+TPU from ExtrimTextil, I estimate the TPU thickness to be 0.10-0.13 mm, which should be good. Before starting your packraft, however, try folding a small piece in half, TPU side to TPU side, and seal around the edges to create an air bubble. Then try squeezing the air bubble to make sure the fabric is airtight – you can place something heavy on top of it and leave it for a few hours to be sure no air escapes.

          1. Thanks. What I ended up doing was a kind of a pocket (only three sides sealed) in which I blow some air with an air-compressor gun. The air doesn’t come out from the sealing or the fabric, only from where I put in the gun. I’ve cut too small of a piece of fabric to make the bubble you suggested but it seems good to me.

  2. Hi Matt,

    Will you be taking orders for your fabric soon? Also, when do you return from vacation?



    1. There was a short delay at the factory, but fabrics should arrive in Canada on the 26th and I’ll be shipping soon thereafter!

      I’ll be home later this weekend 🙂

  3. Do you have any plans to make a green fabric available similar to the “cedar green” Alpacka use?

    1. Hi Nick,

      I will offer more colours in the future, but the timing will depend on how quickly my current stock of fabric declines – the earliest possible date would be in several months.
