## Description

The N-Ferno 6471 Heavy-Duty Insulated Bib Overalls are designed to be worn over work pants for warmth and durability in extremely cold environments. The 500D polyester oxford with breathable water-repellent coating protects from the elements, while 3M Thinsulate insulation traps heat for enhanced warmth. These black winter work bibs hide dirt and feature 1600D reinforcements to hold up through the toughest work conditions. For convenient storage, these work bibs have 1 chest pocket and 2 side pockets. Zippers on each leg make it easy to pull on and take off the insulated bib overalls without removing work boots. 4-way stretch sides enhance comfort where you need it, and adjustable elastic straps make for a custom fit. 3M reflective accents keep wearers safe and seen. These winter work bibs are a great choice for warmth while resisting heavy wear and tear in industries such as mining, construction and manufacturing.

Review: The Best - I was just putting these on to go out into the weather on a nasty day. It's been 2 years of hard winter use and thought I would give a review. I operate a barge and manage a large mountain property year-round on the highest elevation lake east of the Mississippi. It gets brutally cold up here, and the steel barge is hard on clothing. This coat and bib combo is the bomb. I have worked a lot of industrial and construction jobs all over the country in challenging winter environemnts including 9k feet in the Rockies and the northern end of the Appalachians in Maine, and this is the only outerwear that has held up. The parka hood is big enough to comfortably fit a hard hat, and the padded knee pads on the bibs are a major bonus. The material is super rugged but quiet and flexible, and the layer of insulation is just right like baby bear's porridge, not too hot and not too cold. If you've been looking for industrial outerwear for cold climates at an affordable price, look no further.
Review: Quality product and worth the money - I finally had to replace my 20+ year old winter bibs and I toiled over may different pairs off desertcart. I finally decided on these and WOW. Perfect timing because we had the worst winter in a very long time. These things were amazing! Comfortable and warm.

### ⭐⭐⭐⭐⭐ Worth every penny
*by A***R on February 9, 2024*

I was unsure about buying these. I’ve had some bibs before but never fit well. These fit perfectly. Stayed dry and warm in a snow storm. Comfortable to wear and so far holding up really well!!! Great product!
