If you're searching for alternatives to Ventile that won't break the bank, I’d recommend checking out Gore-Tex or Polartec NeoShell. I’ve used both for outdoor gear, and they really hold up against the elements while still allowing for breathability. If you’re after something a bit lighter, consider cotton or nylon blends that have a durable water repellent (DWR) finish. I’ve found those work well for casual outdoor activities. Just make sure you pick a fabric with a decent weight for better performance.
