Where are the homeless niche safety products at?

There's tons of safety products for just about any walk of life, but how many are out there for people experiencing homelessness?

Forget safety items like pepper-spray, they're confiscated at shelters.

Forget protective eye gear, they can't stand up to the amount of debris like sand, mud, and twigs hard sleepers come in contact regularly.

The rest of the like such as oil resistant non-slip footwear...can't hold up two weeks off the beaten path.

Just sayin'.
