So this Work King safety jacket is seriously visible and warm - perfect for anyone working in low-light conditions or construction sites. The hi-vis material with 3M Scotchlite reflective strips makes you stand out like crazy in the dark, which is exactly what you want when you're working near traffic or machinery. The 4-inch contrast backing just amps up that visibility even more. It's quilted with polyester insulation that keeps you warm without making you feel like the Michelin Man, and the 100% polyester fabric is durable enough to handle job site abuse. The rib knit collar and cuffs help keep cold air out, and there's an inside cell pocket plus dual inner pockets for storing your stuff. The drop back tail and rib knit back armhole gussets give you better coverage and freedom of movement, which is so important when you're actually working in these things. There are even dual microphone loops if you need to use communication equipment. Whether you're in construction, road work, security, or any job where visibility matters, this jacket has your back. It's the kind of safety gear that actually makes you feel safer when you're out there in the dark or bad weather.
