it's a heavy-duty mask... somehow very comfortable to use and keep for many hours. Very raccomended
breathable, protective, no sweat and filter pocket available, great attention to details.
The inside lining is made out of air-mesh, like what's in sneakers, this allows for air flow and since it's synthetic its automatically moisture wicking.
AND SUPER STYLEEE, the inside mesh lining is safety orange which is not visible form outside, but when it does show for a sec it's a nice pop of color. The bungee cords can be arranged to be around the ear or over the head and around the neck. plus they have toggles for adjusting the cord. the cords are attached to the mash via a grosgrain binding that has a nice pop of texture and color.
there is a nice velcro pocket to add PM25 filters, or waht ever filter you use. the size is on the bigger side, but fits me perfectly, i think it would also work well for people with bears.
