Thanks Katharina for the kudos!
Thanks for the feedback, somehow the shipping page got left off the info tab. I will get that fixed soon.
In the meantime, our preferred shipping is via USPS. For a limited time, domestic shipping (within the USA) is FREE. For international shipping, I will charge only what we are charged. I would prefer to ship via Priority Mail® International. This starts at $11.95 for Canada. I will send a follow up invoice for the shipping via Paypal after the box has shipped. If some other form of shipping is preferred (be it domestic or international), just shoot me an email at firstname.lastname@example.org, and we can sort it out. I am quite flexible.
Regarding the durability of the fabric:
First off, I found a typo in the descriptions of the fabric. It should be TX07, not VX07. Sorry about that, still working out the kinks here. I'll have that fixed soon as well.
I am a big fan of the TX07. I find it is a good balance between weight and durability. The face fabric is a 70 denier ripstop nylon. The fabric is not as abrasion resistant as the Dyneema Gridstop, but I certainly find it durable enough. However, the waterproofness of the VX07 is better, and lasts longer, as it is not a coating, but rather a PET film that provides the waterproofing. Also, this fabric weighs in at about 3.2 ounces per yard, so it is a bit lighter than the fabric you referred to. I use the TX07 in my personal pack, and have found it quite sufficient as a pack material.
For those who are wondering, the difference between the VX07 and TX07 is that the TX07 does not have the 50 denier polyester backing on the 'wrong' side of the fabric. It also weighs 1.6oz/per square yard less than the VX07.
Thanks for bearing with us through through these early stages.
