I use duckduckgo and don't share my location so it defaults to US. I saw them in an image search but with nothing next to them for scale had no idea of size until I read their site details. Looks like something you could DIY if you sew?
I could also have a crack at making what you're looking for if you want. Got a load of 600d cordura and velcro left still from other projects. All I'd ask is a few quid for materials
