Some of the lighter Corduras? Or no-brand nylon like this? https://www.extremtextil.de/en/nylon-210den-pu-coated-130g-sqm.html You'd have to find a UK supplier, but PU coated and 100-150 g/sqm should be fine? This has a 5000mm water column, the ExtremTextil customer service recommended it to me as a drawcord collar and it's been perfect for that.
Oh yeah that looks perfect, hadn't considered just a lighter one could be available – doy. Thanks. Do you have any pics of the one you used after being sewn?
