I was contacted about this product by its inventor, Garfield, of Evergreen Gear. After 20+ years in the construction industry, he designed this for himself: a heavy American canvas work vest made in the USA, built for all-day outdoor and field use. After testing it out myself, I can tell you this thing is a BEAST. You can immediately recognize the quality just by holding it in your hand, made with heavy duty cotton canvas will surely break in over time. This vest from Evergreen Gear is designed around tool access: tons of organized pockets, a drill clip attachment point, and integrated concealed-carry with holster support. If you're someone who works with tools every day, you may have just found your new favorite work/EDC vest.
