I love this Biberall !!! Buy your Carhartt products from Carhartt.com !! Amazon and some of the other retailers resell opened or gently used items. How do you know your Carhartt is brand new? Spend the extra money and get an original Carhartt !! This was my first Carhartt purchase, 11/2016. For me, I have to back up the truck on the Extremes Biberall 1000 Denier Biberall. It is everything that I expected. One pair is not enough. If someone were to steal my only pair, I would be screwed. I like a very, warm winter garment. This Biberall is as warm as a sleeping bag!!! When I was figuring out how to put on the biberall, I was overcome by the insulation. I should have walked outside of my heated home. Do not wear these overalls indoors, with sub- layers underneath on your body !!! You very possibly could get dehydrated or light-headed or pass-out or get a headache. Also, I bought my pair 2 sizes bigger in the inseam and waist. Carhartt recommends otherwise. Do not listen to Carhartt's recommendation. When you size up, you can wear base layers, mid layers, heavy-weight layers, and wool-layers underneath!! If you do not take my advice and neglect to size up, then you will not be able to put on 2-4 sub-layers. Also, Carhartt says that this biberall will shrink by 2-4% over its useful life. Buy a size larger, at least. This way when your biberall SHRINKS ON YOU, it will shrink to a very, comfortable size. Shrinkage should make this garment better with age. But, if you buy the exact size you need----your biberalls will get WORSE with age because of shrinkage! Washing gradually kill all garments. To cut down on washes for this biberall, buy wool long-johns AND buy wool pants and a wool top. Wool cleans itself !! You will never regret buying wool !! With a wool layer underneath this biberall, rotting bacteria will never attach to your biberalls. Therefore, the inside will be far less odoriferous. For me, Carhartt's biberalls offer the best mix of quality and value. I don't want to look fashionable. I just want to stay warm. This biberall is as warm as a sleeping bag, when you size up two sizes, and you wear base-layers underneath. I saw only one straggling string on the whole biberall. But, this biberall is triple stitched. And double stiched in other areas. So, I have full confidence that this biberall will go down to my son, as long as I do not sweat on the insulation. The outside of this biberall is very tough!! The outside looks great, and performs great. I can't wait to buy my next Carhartt overalls. I have plans to buy another Extremes Biberall. Must have two of these for the winter. And, I gotta try the Carhartt Coverall. If the Extreme Biberall functioned like a sleeping bag, then I wonder how warm the Extreme Coverall will be. Like I said, BACK UP THE TRUCK !!! I will be ordering extra pairs just because the 1000 cordura nylon is awesome. The insulation is awesome. Bonus: When you buy from Carhartt.com, you can return/ not exchange, your order for a full refund. Fast Shipping Too! !! Don't forget to buy WOOL socks with this Biberall BACK UP THE TRUCK !!!
