Thread count looks a little low.
Looks "a little low" compared to what?
The canopy fabric, and other kite fabrics.

Relying on adhesive could be interesting in a few years.

Did it ever? Higher thread count just is a nicer looking and more stable fabric. I am not sure why in this and previous dyneema fabrics they have chosen lamination over more weaving.

Sorry, thought you're refering to the sewing thread count.

The canopy ripstop looks like any other D2, I can't see any lower thread count there.

I beleive the Aluula lamination is there to 'lock' the looose weave. A tighter weave with such slippery yarn won't make the fabric stable enough. For strengh they don't need a higher count, the tests they've shown are more than clear on this. Bias stability (low stretch) comes only when the fabric is tensioned (inflated LE), this is my understanding so far. Curious to see that thing with the thin bladder increasing the stiffness.
Wait to see the new Duotone lightweight dacron. Not as light as the Aluula, but 'lower thread count' than conventional dacron.

As for the adhesive tape - LEI canopy seams have always been relying on it. Without it a canopy will tear apart at the first loop or harder landidng, especially when new and crispy.

Yes the lamination would be to lock the weave. In previous versions there was no weave. Weaving technically should make things weaker, but is necessary to have normal fabrics. The thread count looks low to me when it is easy to see the threads. It would not make a good canopy material like that. With a gain in weight to fill so large holes with coating or what every laminate.

OK. But again I am concerned with the lower thread count. In foil kites it leads to more porosity. This would affect the canopy on LEIs, but I wonder about the bladder as well. The fabric is less smooth and the gaps may increase stress. Overall I am really wondering about longevity, glue in general is known to be less reliable or unpredictable.

Well foil kites do not use it. I am aware of it being used say in repairs to help with alignment. I don't see it contributing much strength, other glues could but they all would seem to eventually deteriorate too much. Stitching is the most reliable join.
