A beginner should rely on a bright polyester vest lime with reflective features for basic visibility during standard tasks, while a pro may choose a version with larger sizes or consistent lime-green visibility for longer shifts and varied sites. Both rely on the same color and reflective properties to stay visible, but experience often correlates with fit and durability considerations, so pick a model in sizes like L, XL, or XXL to accommodate layers. For safety, keep the vest on in daytime and low light, and pair it with other PPE as required by your site’s rules.
