Our work vest is constructed from lightweight, breathable, yet extremely durable polyester with a heavy-duty smooth operating zipper. It is ideal for those working at heights in or around construction, utility or traffic applications. Delta harnesses combine a set of industry-first advancements, with popular features making them the workhorse of the industry. Today's Delta represents the culmination of more than twenty years of design, research, manufacturing know how and on the job performance. Delta harnesses are as tough as the guys who wear them. They feature coated, corrosion-resistant hardware, water-repellant and abrasion-resistant webbing and a build quality that is second to none. A patented triangular design gives Delta harnesses a shape of their own, so you can don them quickly and easily. Throw it in the tool-box or in the back of your truck, think you can tangle it? Just pick it up and it's ready to put on, tangle-free. The Delta pad also incorporates a web spreading design, positioning webbing wider apart on shoulder straps to eliminate abrasion on your neck.
