I think this mask would be fine for gardening
I think this mask would be fine for gardening, lawn mowing, walking, if you are sensitive to airborne allergens and particles. I was looking for a mask for bicycling, since I cycle through downtown and live in a pollen-a-plenty locale. It does not work for heavy breathing or a work out. As others have mentioned, it sags into your mouth if you breathe hard. In addition, as this implies, sucking in air gets to be really hard, and you might just pass out. I will keep it for when I mow or weed whack, but that's about it.
