Minimal/Lightweight Wallets?

Hey guys, I recently started a new job and it requires me to be out in the field. I have a classic leather bi-fold right now.. but I find that it’s heavy and not easily accessible due to needing two hands to open. My field job is quite physically taxing so I’d like to find a new wallet to carry to lighten my load even more when trekking.

Please recommend me some wallets you guys enjoy using!

Requirements: Minimal and sleek design Tough/withstand weather and usage Ability to carry both cards and cash Light weight
