Tingley's two-tone surveyor vests are a high visibility necessity if you need a lot of on-person storage while in the field. There are eight pockets in total, five exterior and three interior pockets to hold all of your work gear. The two-tone pattern increases contrast and visibility, blending both safety colors. The front of this vest is a solid knit fabric, while the backside is a mesh for added airflow and breathability. It is lightweight and conforms to safety regulations.
