Reviews

The Warmest I’ve purchased

"Designed warm enough for 30 below, great flexibility for a 5’8 and 200+ guy that be in the cold for 8-12 hours. The stretch material on the bids will come in handy for more layer and great flexibility."

— Raymond G. (5/5)

"Perfect fit! Awesome feels! Thank you for making the product work! I love them now I need the jacket lol 😁"

— Heather (5/5)

Don't trust the warranty

"Warranty is a scam! I've been trying to exchange the item because it got cut but it says that the same size isn't available, while when you try to buy it it is available! Only so you can't return the item."

— Ramzy (1/5)

best winter overalls

"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"

— andrew m. (5/5)

Worth every penny!!

"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!"

— Will (5/5)

Almost perfect

"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."

— David M. (4/5)

"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"

Q&A

Are your women’s t4 bids the same ones as men’s? Do you have plans for XS women’s t4’s?
Hi there, thanks for reaching out. Yes, our T3 and T4 bibs are unisex sizing! At this time we do not have plans to expand sizing but I'll be sure to pass your feedback along!
Do any of your Bibs have back pockets?
Hi Jay, Thanks for reaching out. While our T3 and T4 bibs have a total of 8 pockets, they do not have back pockets. However, our T1 Overalls do have rear pockets! Thank you, TRUEWERK
Going to be working in Antarctica soon. Would these hold up or be considered extreme cold weather gear?
Yes. We had a customer wearing them for a winter on the North Slope of Alaska and he loved them.
How much does the T4 winter bibs weigh in large? And what's the inseam length?
Inseam depends on the length selection. Short - 30 Regular - 32 Long - 34
I wear 30w 34 pants. Would the regular length be long enough?
Yup that would work. The long is a 34 inseam but I think you could wear a regular length at the 32 inseam!
