The 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 for clipping radios or scanners and 2 d-rings for convenient access to keys, ID badge, glove clips, etc. 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. 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. 3M THINSULATE INSULATION Designed with 200g of 3M Thinsulate insulation, these winter coveralls traps heat for warmth in extreme cold from -10 F to -50 F (-23 C to -46 C). The 3M Thinsulate is 30 thinner in profile compared to standard poly fill and has a higher loft design, making it condense at a much slower rate and offers more thermal retention than standard poly fillincreasing its life integrity. Minimized washing will extend the overall life of the thermal, insulated garment. CLO RATINGS Insulation performance is measured by CLO ratingswhich 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).
