Made from heavy-duty polyurethane-coated 300 denier Trilobal Rip-Stop polyester that is waterproof, extremely durable, and resistant to abrasion, rips, snags or tearing. Gussets on both sides allow a fair amount of give, so the vest can be worn over both bulky winter wear and thin summer clothing. Mesh strips on each side for added breathability. Features 3M™ Scotchlite™ silver reflective tape on a 4” contrasting orange background.
