I've had leather in the past... no more... if something spills, even with a liner, forget-about-it. I also have a Red Oxx smaller dopp kit and it's nice, but bulky.
About ten years ago I bought a Victorinox Slimline Dopp Kit and it is my absolute go-to for all traveling and workout-gym use. It is in immaculate condition after all these years, looks to be a type of ballistic material and frankly, it is BULLETPROOF. It's not fancy, in black, simple design does everything I need it to do.
