4.35oz bivy

From the photos and description, it is not obvious where the zippers are.

Most have either one down the side, or else one across the chest, or both.

ah snap, that is one nice bivy! Like Bob, I'm wondering if this has a over the chest and down the side style zipper? If not, can we add one for a custom fee?

The SevenD-s fabric sounds interesting fa sho'. Looking forward to seeing it in some more projects and hearing some reviews.

The zippers are across the chest.

Basically its .65oz sil-nylon. I spent about a year working with several mills to get a 15D fabric siliconized that would be appreciably lighter than 30D sil, and was slowing making progress when I was contacted by the manufactures of the SevenD-s. They had siliconized fabrics waaayyy lighter than anyone else had been working with. So I gave up my quest. To be clear, it is not just SevenD with silicone on at, so the name may add some confusion. The SevenD-s is a different base fabric entirerly. The SevenD-s is milled in narrower widths than standard SevenD, and has a micro(.035"x.035")ripstop grid in it, where as standard SevenD has a larger rectangular ripstop grid. because it is siliconized and has more check threads, its much stronger than the standard SevenD also.

How is the durability of the SevenD-S fabric compared to say .51 or .74 cuben?

The only reason that I hesitate to buy it is because it is constructed of nearly entirely new materials.
