Steven,

It's just regular nylon ripstop in a 1.0 oz/syd weight. Just like pertex quantum weight, though different feel. So strength will be same as most 1.0 fabrics. I saw it recently and really liked it. The tech is very intriguing and seems solid, user reports concur. Given the choice I would go with the nano over quantum, since it has a permanent DWR.

Thanx, Here's what Justin at FF customer service had to say as well.

I have found the Nano treatment to be durable over the year of use I have put on my Hyperion Jacket and Swallow Sleeping Bags. Nano is a new fabric for us so this past year is the extent of the empirical data we have. There is no doubt you make a shift to weight savings and will sacrifice durability. For bags, I think it is an easy choice. For jackets, the weight savings is nice but the decision is influenced by needs and history. It is worth noting that the Nano is more water resistant than Epic.

I requested info from Justin at FF as well. Aside from what you've already posted, he also added that Nano is less breathable than either Epic or eVENT – which is surprising. Justin attributed this to the nanosphere coating. But my understanding of nanosphere is that silica nanoparticles are bonded to the fabric surface in gel form. The coating itself, I'd assumed, couldn't possibly affect breathability, as the nanoparticles would be much much too small, and the coating much to thin, to reduce the pore size of the fabric. Perhaps the gel used in the application process does however.

Impressive though that the result is more water-resistant than Epic.
