For dust masks - I occasionally use these: Dustproof Mask Activated Carbon Filtration Exhaust Gas Anti Pollen Allergy PM2.5 N99 Face Mask for Running Cycling and Other Outdoor Activities https://www.amazon.com/dp/B07DX4LCD5/ref=cm_sw_r_cp_api_i_Vb1rCbZZH071G
Essentially an N95 mask with a neoprene shell that makes it a lot easier to take on and off / get a good seal with. They also pack flat, so pretty convenient.
Otherwise, the Shemagh works just fine for me too.
