Anyone understand the different variants of hybrid cuben out there? I'd love to know the situation with different weights of polyester and cuben linings.
From this thread and the McHale site, we see references to CT9, CT13 and CT22 hybrid cuben fabrics, and references to weights of 3.4, 3.6oz & 4.2oz per yard. We are told CT22 weighs about the same as 210D Dyneema grid, and McHale's site says CT13 is 3.6oz stuff. Perhaps CT9 is likely the 3.4oz stuff and CT22 is 4.2oz/yd unless Dan's using more than 3 variants. Maybe the last number refer to denier? (90D, 130D, 220D?).
HMG doesn't give very much info on their site, but the word on BPL is that it's 3.3oz. Zpacks uses stuff they claim is 2.92oz/yd (99g/m2) and uses 50D polyester. ULA has hybrid cuben that spec'd slightly heavier (102g/m2), which works out to 3.0oz/yd2. From ULA, this 3.0oz stuff has the code CT5K.18/wov32.c. The first half of that is easily understood but 'wov32' is a mystery because 32 seems too low to be denier.
I got a sample of the stuff from ULA and there's no perceivable difference in the polyester between that and HMG's stuff.
