Keep it simple and practical
I use a LewisClark cloth bifold with a zipper. Why? it is very durable, yet very thin and lightweight (minimum bulk). It has a zipper to secure the contents. It has two belt loops on the short end to secure it inside pants below the belt (if desired), one brown, one black, I wear a black belt, so I cut off the brown one. It is cheap and available at Amazon. Have used these for years. Would not switch to anything else. Washable!
My motto: keep it simple, keep it practical, focus on function, not aesthetics. After all, it's just a wallet in a pocket, not a wedding suit.
