Ergodyne 41253 Insulated Freezer Jacket Medium Navy

Product Description

The ERGODYNE 41253 is the N-Ferno 6476 thermal insulated freezer jacket, engineered for workers in cold storage facilities, walk-in coolers, freezer rooms, and demanding outdoor environments. The shell is 100% ripstop polyester with a water-resistant PU coating, and the interior uses 200 grams of 3M Thinsulate insulation rated to perform in temperatures as low as -50 degrees F (-46 degrees C). With a CLO rating of 2.59, this jacket is rated for moderate-activity workers up to a full 8-hour shift at -45 degrees F (-43 degrees C) and up to 5 hours at -50 degrees F (-46 degrees C). The 3M Thinsulate fill is 30% thinner in profile than standard poly fill and maintains loft longer, extending the thermal life of the garment.

This jacket is designed for workers in cold storage and freezer environments across distribution, warehousing, food processing, construction, mining, and similar industries. It suits a range of activity levels: from light-duty forklift operators and equipment operators to moderate-activity roles such as picking, packaging, and delivery. It also fits outdoor recreational use including hiking and snowmobiling. The ripstop polyester shell and water-resistant coating stand up to moisture and abrasion without restricting movement or dexterity. Minimizing washing will extend the overall service life of the thermal insulation.

Installation Notes

No tools or trade installation required. Inspect the garment for damage to seams, shell, or insulation before each use in extreme cold environments. Follow the manufacturer care label instructions - minimize washing frequency to preserve thermal loft and insulation performance. Replace the garment if the shell coating or insulation shows signs of degradation.
