    X-Pac for Tarps and Tents

    I just came across someone on a FB gear page building tents out of X-Pac material. I know this stuff is used for backpacks, is generally considered waterproof, has greater abrasion resistance than DCF, has much less stretch than silnylon and greater tear-resistance than silpoly.

    So my questions is....why isn't X-Pac used in the construction of tarps and tents?

    IMO it is really heavy and really expensive compared to most lightweight backpacking tent/tarp material.

    But if it has the better strength for the same weight then surely it should be lighter...and isn't it cheaper than DCF?

    Same strength/weight when compared to which fabric? It doesn't have better strength for the same weight as a Dyneema fabric product. Xpac is basically just layers of fabric glued together, so it isn't special in the sense of using high-tech fibers to cut weight. It is a laminate with a typical construction of a nylon/polyester face fabric (Like a 70d fabric, so abrasion resistance of a 2 oz nylon) , a pet film for waterproofing, and a 50d polyester taffeta backing for stabilization and stitch holding.

    It is cheaper than DCF but still 4 times the cost of SilPoly or nylon. Even the lightest sold variant of X-Pac (VX04), which is a 40d face laminate, weighs 4 oz/sq. yd which is about 8 times heaver than the normally used 0.51 DCF material and 4 times the weight of the normally used 1.1 silpoly/nylon. I also think another downfall of XPAC fabrics as a tarp or tent would be packability. It is a very stiff fabric, so 10 yards of it in the form of a tarp would be really difficult to fit in a pack

    That being said, I do think XPAC is a super awesome option for bags packs/etc. because it is a laminate and is fundamentally waterproof. And since it has a lot of the properties of heavier DCF Hybrids (The ones with a polyester face ), it does make it a fantastic price alternative as well!
    All of this IMHO of course, some may find X-Pac stuff to be great for their tarps etc. I just think these may be reasons are why we don't see more of them out there.

    Too heavy & bulky to pack, more expensive than silnylon.
