    Zpack tarps ...how are they ?

    looking for some input on Zpacks Hammock tarp
    the price is right for me at $235 ... but wanted to see what everyone thinks of them
    i know he sews his ridgeline seam... has there been any problems with this i know from my cuben stuff sacks that cuben with sewn seams can wear out over time....
    It puts the Underquilt on it's hammock ... It does this whenever it gets cold

    imho, hyoh, per ush....

    i'd never do a cooben tarp with sewn ridge.
    wv, while not explicitly proclaiming... sold me on the bonded ridge.
    stormcrow has followed suit.. as has mt.fitter, or lawson..... and others i'm sure
    i've failed to represent. (sorry_)

    to me, it don't make sense to sew, compromise the seam.... and now add the weight of a fingered-personal hand-jobby sealant with silnet.

    hmmker for a day -
    personally, i want an 11' ridge, by 12' sides-- likely a 3 panel bond. once the weight hits 11 oz for that huge of a tarp... who'd care..... the ultimate 4 season at 11 oz.

    I'm a DIY kind of person, and unless they are using some thing to bond that I can't get I will sew. I have tested both and my bonds do not hold up as well as sewing. Z Packs uses a Feld Seam with a extra stich down the center, I have used the same. You will not pull it apart. Feld seams are the same seam used on jeans.
    Bonding leaves the material kind of stiff at the bond. I have some concers that the bonded area will crack over time. I may be wrong on that, time will tell.

    It's good to have this kind of contribution added to the discussion, because we have a tendency to enthusiastically endorse things we like and hold back on criticisms. That makes posts with doubts and poor test results all the more valuable. It's encouraging that there haven't been reports of cuben (CTF3) tarps failing (yet). While I do prefer one type of bonding for CTF3 because it works well and fits the scale and type of my operations, I believe (and hope) that the others that have been described on HF are also eminently useable. That includes the sewn ridgelines from Zpacks.

    Traftonm, can you give us a bit more detail on your tests? Bonding agent, width of seam, type of seam, curing time after bonding, and stuff like that would all be helpful. Don't feel you have to rival Underwriters Laboratories. My mind boggles at kilo-fig-newtons anyway.

    yeah i'm a BIG DIY guy myself thats why i asked about the RL seam i know from stuff sacks i have in cuben that cuben sometimes does not like to be sewn... and it's good to hear about the glue not being 100% ...
    that was going to be my next question so you killed 2 birds with one stone
    this is VERY good input and was done the right way without bashing a vendor or a person... this is how you post Best post of the year

    I agree WV very good post it was done in a way that didn't bash anyone and gave useful information ...i also would like to know more about the bonding he use on the test ... so i know for the future if i get a tarp with a bonded seam ...

    It's not procrastinating, its proactively delaying the implementation of the energy-intensive phase of the project until the enthusiasm factor is at its maximum effectiveness.

    sewn, taped, or bonded

    I have yet to hear of anyone having a problem with Zpack's sewn seams, but he is taping on them now.

    Anyone could order some Zpack tape and install it on a sewn seam, either after cleaning off some of the seam sealer, or on the underside, away from the seam sealer.

    I have had mine for awhile now. Been on two trips with 40+ mph winds. It has performed and held up well. Joe does outstanding work and has excellent service.

    I don't think you would an issue with one of Joe's tarps. Very nice. Here is another one to look at too.
