"the best winter overalls i have bought , put the m2 jogger sweat pants as base layer , i live in buffalo ny and worked outside at the new bills stadium every day in these with that base lay as the suggest and was never cold during any wind and snow storms i tell everyone who asks me about them exactly where to buy them and they won't be disappointed"
"Bought these the beginning of 2026 and paired it with my Tower Parka. Snow in Wichita, Kansas didn't even do anything! Completely snow proof,wind proof,and tear resistant in -10° with 25mph winds! I had a base layer,mid layer,and the T3 pants under them. I was sweating with them on lol! If you live where it's cold and windy,you definitely need these!"
"These have been great technical work bibs. I purchased these for backcountry SAR missions and polar construction. They're definitely warm and the knee pads are great for when you're working on your knees in the snow for an extended period of time. The interior snow cuff can get a little annoying, and I miss the pen pocket, but overall I've really liked these bibs."
"Great bib and amazing customer service. But they have changed the quality of this bib. I have ordered it 2 separate times and both times the quality is not like the first bib i got. Not sure what happened if they changed manufacturers or what but they need to go back to the material they once had. It was way more duarble this new fabric seems cheap and also the clor isnt the same either"
"The warmest and most free moving insulated bibs I’ve ever worn. Work post frame construction and can crawl trusses and crawl around on the ground with zero restriction. Chest portion fits snug keeping warmth in and making coats fit over nicely. Knee pads are also a life saver on frozen ground and snow."
"I wore these bib overalls for a full winter season of outdoor work, specifically forming and pouring concrete. They are stretchy, very warm, and the fit was excellent; at 6'1" and 180 lbs, the fit was snug enough to keep out the wind and cold. However, the outer material is thin and prone to ripping. Because of the fabric type, you can’t simply sew it back together once it tears, which leaves the internal polyester stuffing exposed. Given the price, I don’t believe these are worth the investment for heavy labor. From now on, I’ll be sticking with pairs that have a more durable outer shell, even if they offer less stretch. While these would be great for recreation or light outdoor tasks, they aren't ideal for environments with sharp or rough materials. I wish there were a way to repair the fabric, but it just doesn't seem possible."
"Very warm, yet still lightweight and not bulky"
"Not sure what has happened but there has been some material change. This is not the same material on the prior t4 bib that i had. This is my second time returning this bib because of the material issue. I hope they bring back the old bib material it was so much better and sturdier."
"Have used these bibs for skiing and working outdoors. They are thin enough that movement is effortless, but incredibly warm for all day outdoor warmth. Great product and washes like a dream!"
