One of the most important things to know the difference of when shopping for work wear is the difference in the types of lining. One type of lining might be made for extreme cold temperature, and another might be made for a warmer work environment with a slight wind chill. Without being informed on the topic you can really leave yourself in a bad place. You don’t want to be caught wearing a thick lining like the arctic quilt lining during a warm spring day. The Arctic Quilt lining has been created for one environment as the name indicated; the arctic.
I’m going to demonstrate the differences in Carhartt linings, and explain what advantages and disadvantages each lining has. This way while purchasing a Carhartt product you’ll know which one’s appropriate depending on the work that you do.
The Carhartt Thermal Lining is the thinnest and least warm lining Carhartt makes. It has a thickness, and softness comparable to a Carhartt flannel shirt. This lining is perfect for keeping heat bottled inside, and keeping your body warm at all times. The Carhartt Thermal lining is perfect for 4 season wear, it’s warm enough after dressing in layers for the coldest winters, yet thin enough to be worn in the spring over a t-shirt. It’s a very soft, thin and comfortable lining made to be worn in all seasons.
Carhartt Fleece lining is slightly thicker then the Carhartt Thermal Lining. This lining is very lightweight because it’s made from 100% polyester fleece. The Carhartt Fleece lining is very similar to the Carhartt Thermal Lining, because it is made to be worn for 4 out of 4 seasons, comfortably. This lining is slightly softer, and more flexible then the Carhartt Thermal Lining and if layered properly it can be worn during the coldest winters. This is a great lining, if 
you purchase an item with it that you know you’re going to use every day of the year.
The Carhartt Blanket lining is slightly thicker then the Carhartt Fleece lining, because it’s medium-weight insulation. This is the happy medium in the lining family, the middle child if you will. This lining is excellent for active work. If you’re working an entire day, while wearing this lining you will feel like you’re wrapped up in a flannel blanket; comfortable and warm. This is because the Carhartt Blanket lining utilizes a heavy flannel material. This lining is perfect for those cold days, where you forgot to put a thermal on underneath.
The Carhartt Quilt Lining is slightly thicker then the Carhartt Blanket lining. This lining is great because it has the feel of a soft flannel shirt. However, because of its construction the Carhartt Red Quilt Lining is very thick, and great for 
keeping warm in the coldest environments. The Carhartt Red Quilt Lining is a heavyweight insulation consisting of soft flannel material quilted to heavy polyester filling. The best thing about this lining is, that’s its thick but not bulky. This way you will be able to function while staying very warm all day long.
The Carhartt Sherpa Lining is slightly thicker then the Carhartt Red Quilt Lining. This lining is a white nubby, soft pile material that provides lots of warmth without being overly bulky. The reason that the Carhartt Sherpa Lining is so warm is because it’s made of 70% acrylic and 30% polyester material. The most important thing to know about the Carhartt Sherpa Lining is that it keeps moisture away from the skin to keep you dry all day. The polyester pulls the moisture in and the result is more comfortable, drier clothes.
The Carhartt Flannel Lining is slightly thicker then the Carhartt Sherpa Lining. The flannel lining is made of flannel, as the name indicated. Not just any flannel though, Carhartt’s most durable and thick flannel. This lining will ensure warmth no matter what temperature or environment you’re working in. This lining is quilted to a layer of polyester insulation for extra warmth. The Carhartt Flannel lining is one of the softest and comfortable linings Carhartt has to offer. It’s also the 2nd thickest lining Carhartt makes.
The Carhartt Arctic-Grade Lining is slightly thicker then the Carhartt Flannel Lining. The Carhartt Arctic-Grade lining is the thickest lining that Carhartt offers its customers. This lining is made for going on expeditions in the Arctic. You will not even feel the cold, while working outside if you purchase the Arctic-Grade lining. This is also one of Carhartts most popular linings, for obvious reasons. The Carhartt Arctic-Grade lining is made from nylon taffeta 
material which is quilted to a layer of high loft polyester. This lining is perfect for activities, like 6 A.M hunts in the Rockies, or just for working in a miserable climate, like most workers have to face.
Hopefully this guide is going to help you in making your next decision on which Carhartt lining is appropriate for you. Just remember, they all have their purposes, and it’s not a bad idea to get one really thin lined item, and one Arctic or Flannel lined item. It’s always good to be prepared. I always say it’s better to have a jacket and not need it, then to not have a jacket and need it. The same thing goes for lining.
