Hi all, I'm after a lightweight bivvy bag for fairweather three season use (really just something to keep the wind and light rain/dew off my sleeping bag). I'm unwilling to pay the 'ultralightweight' tax so thought I'd try my hand at a DIY one. I'm a longtime jardine afficianodo and can use a sewing machine etc.
I'll loosely be following this template https://gerald-zojer.com/blog/simple-diy-bivy-bag-windproof-and-water-repellent-with-patterns/ with drawcord around shoulders and neck, but adding a head footprint with 'pocket' in which to stuff my pillow (down jacket).
I'll have a closed cell foam mat between bag and ground, so I will use the same fabric top and bottom. I'm aware of pennine outdoor/pro fabrics. Aiming for 300g or below in weight. Bivvy bag will be tailored to my mummy bag, happy to go without space for cooking/rucksack boots etc. Any tips on what fabric I should buy? Obviously its the age old trade off between durability/waterproofness and weight.
Thanks for any help
