I use thisto make ultralight rain pants. Works great!!!
Exactly what I was hoping for with respect to weight and feel. I will be using to make a vapor liner for keeping my quilt dry when sleeping in a bivy bag, a rain kilt, and a pack cover.
Used this to make a simple splash bivy for extra protection under my Gatewood Cape tarp. I folded the long sides to the centerline but only sewed a simple footbox: The foot end is closed and the long centerline seam only sewn up about a foot. The rest is just folded into the centerline. In good weather it is just a double layer below me. But if the weather turns bad, I can slip into the footbox and fold an upwind side flap over myself. On the head end I sewed on a piece of 0.5 oz noseeum netting. It stays under me also but if the bugs come out I flip it over me. There is a suspension point to pull it away from my face. Just over 7 oz with the sack, inexpensive, and a grand total of three straight seams. Didn't have any issue handling or sewing the material. Thought is worked well.
I used this to make a simple groundsheet/cape and it is excellent, being light and packing small whilst being strong and easy(ish) to work, The khaki colour is a sort of greenish sand and a good choice to avoid greens and camos whilst still being discreet but not looking military. In this colour it is almost transparent but, if crumpled up in a stuffsack, it gives the impression of being opaque in use. It is not ripstop in construction (which saves weight) but seems robust and the silicone surface doesn't particularly attract thorns. Moisture beads but doesn't run or shake off particularly, although this may improve over time. Out of the box, it does what it says on the label.
I finally had to consult with a seamstress, who advised me to use newspaper between the material and the gripper foot of the sewing machine.
