I’ve pretty much decided to go with RBTR’s 1.6 oz Silpoly to be as puncture/abrasion-resistant as possible while still remaining pretty light, but I wanted to check with the MYOG mob. Are any of the other RBTR options a better choice like 1.1 oz silpoly or 1.1oz silpoly PU4000 (more waterproof but at a durability cost).  I’m not considering cuben – just way too expensive for my first bivy.
Thanks
