I have been in construction for years and have used many different safety products. Safety Vest has become very important on major construction projects and the safety products you buy from your local lumber company doesn't last. Northern has quality products at a reasonable price! I really like the quality of their safety vest! They not only serve the purpose of being safe but they are also convertible. I like the mesh in the back to allow air but I really enjoy having the zipper in front. The only advice I have when ordering is to order a size bigger than you think you need. Thanks Northern!
