ProFlex 850 Insulated Freezer Gloves are built to keep your hands warm and comfortable in cold storage freezer environments. The palms and fingers feature a silicone pattern and reinforced thumb saddles for extra-strength grip and durability in rough environments. Comfortable neoprene cuffs and lightweight insulation offer full dexterity for all-day use. Designed with 150g of insulation, these winter gloves trap heat for warmth in extreme cold, from -5°F to -20°F (-21°C to -29°C), These winter work gloves meet the EN388: 3X22 B and EN511: 23x glove standards. The thumb, index and middle fingers feature touchscreen-friendly materials so you can swipe, tap and type on smartphones and tablets without having to take your gloves off (does not work with cell phones with screen protectors). The freezer gloves also feature a soft thumb for wiping the nose and brow area, and reflective accents for enhanced wearer visibility. 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). ProFlex 850 Insulated Freezer Gloves has a CLO rating of 1.3 and is rated at a moderate work level in -20°F // -29°C for up to 1 hour (rated up to full 8-hour workday at -5°F // -21°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. IMPORTANT NOTE: Individual thermal performance may vary due to personal and environmental factors. (And by “may”, we mean definitely.) The truth is, thermal ratings are a performance guide, not gospel. The best direction available through exhaustive testing and consideration of three major factors—CLO value (insulation), activity level and time out in the cold. Working safely in bitter cold conditions still requires planning, regular breaks to warm up and the ability to identify common cold stress injuries. Long story longer, we are not liable for any cold-related injuries, including frostbite, that may occur while using our thermal gloves. Our responsibility is to provide you with a high-quality product based on the best testing available, but we cannot control how, where and under what conditions the gloves are used. Stay warm, stay safe, and use our gloves as part of a comprehensive strategy to protect against the cold, not as the sole defense.
