N-Ferno 6475 Insulated Freezer Coveralls are built for warm, durable and comfortable protection in cold storage freezer environments. Designed with 100% ripstop polyester and a water-resistant PU coating, these insulated coveralls stand up against the harshest conditions to provide warmth without restricting movement and dexterity. These insulated coveralls feature a zippered chest pocket, two lower exterior oversized pockets, pen/stylus holder, mic tab and 2 d-rings for convenient access and storage. A snap closure with zippers on each leg make it easy to pull on and take off without removing work boots. A dual button closure on the bottom of the pants makes for an adjustable fit to accommodate varying heights and to ensure pants won’t drag on the floor. A zippered closure with snap storm flap and ribbed knit cuffs help to seal out cold air. Reflective piping and hi-vis yellow material keeps wearers safe and seen. A size label is visible on the arm sleeve for easy viewing when being hung up or stored. 3M™ THINSULATE™ INSULATION: Designed with 200g of 3M™ Thinsulate™ insulation, these winter coveralls traps heat for warmth in extreme cold from -10°F to s -50°F (-23°C to -46°C). The 3M Thinsulate is 30% thinner in profile compared to standard poly fill and also has a higher loft design, making it condense at a much slower rate and offers more thermal retention than standard poly fill—increasing its life integrity. Minimized washing will extend the overall life of the thermal, insulated garment. CLO RATINGS: Insulation performance is measured by CLO ratings—which is a unit of thermal resistance that indicates insulating ability. The higher the CLO value, the higher the amount of warmth a piece of clothing provides. To determine temperature ratings, CLO factors, Metabolic Equivalent of Task (MET) and the time or duration of a task are considered. MET levels can be categorized as light activities (forklift driver, equipment operator), moderate activities (picking & packaging, delivery drivers) and vigorous activities (concrete work, tower climber). N-Ferno 6475 Insulated Freezer Coveralls has a CLO rating of 2.59 and is rated at a moderate work level in -50°F // -46°C temperatures for up to 5 hours (rated up to a full 8-hour workday at -45°F // -43°C). Ideal for those working in cold storage facilities, whether in a cooler or freezer room. Also designed for outdoor workers in any industry, from construction to mining and outdoor recreational activities such as snowmobiling or ice fishing.
