    Well, maybe …

    "Available fall 2013, $2,000; eastonmountainproducts.com."

    … but it doesn't show up on their web site, or a site specific google search.

    …wonder if they have seam problems?

    "The only one left in stock". That's interesting.

    "…and a Cuben Fiber waterproof breathability canopy material with E-Vent."

    So, eVent/Dyneema/eVent, is a little bit different than polyester/Dyneema/polyester.

    I believe most eVent seams are sealed with heat bonded polyurethane tape (?)

    You get Golden Star Brownie Points for this! Both for actually doing the research, and for posting the results. Thank you!

    It does present some very serious problems for seam sealing though – both for Cuben Fibre and for PU-coated. Um …

    Cheers and thanks

    Assuming "Cubic Tech 1B3" with eVent laminate is about as breathable as the cuben eVent material used in Zpacks' rain jackets, and tested by Richard, there will be a problem. While the material might breathe in a jacket, it will not pass water vapor through a tent canopy sufficiently to prevent condensation on the single wall. Sierra Designs wrote to me sometime ago and acknowledged this was their reason for not making single wall WPB tents. TNF's attempt a few years ago with a knock-off of the TT Scarp, but with a WPB single wall, fizzled for this reason. Poetic justice for TT.

    On the more serious issue in this thread, cuben seams, thank you Lawson. More food for thought.
