We worked with 10 surveyors out east to redesign our Lightweight Working Man's Vest. Take a gander at the 13 pockets including two 17" deep zip pockets big enough for your plat map, oversized flashlight or bear spray (we even fit a small machete in here – inside the sheath of course). Pockets enough for tablets, stakes, tape measures, chalk lines, GPS, gloves and more. Durable, 4.7-oz. brushed 70% cotton/30% nylon fabric is light and comfortable to work in, yet unfazed by abrasive environments. Provides UPF 50 sun protection. Vented back with poly mesh on the backside lets in cooling air. Treated to repel water and stains.
