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.

The little stripes of highvis are nice. I bought down a size and they fit like I wanted them to, just a little tighter then a work bib overall. I'm pretty long in the leg and with boots they look proper length. very warm, nice materials. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/403969087-ergodyne-n-ferno-6471-heavy-duty-insulated-bib-overalls-winter](https://www.desertcart.us/products/403969087-ergodyne-n-ferno-6471-heavy-duty-insulated-bib-overalls-winter) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-23*
