They're Carhartt's not much else to say

Verified Buyer Reviewed by Ephblum from Amherst, NY on Wednesday, January 27, 2016
Haven't had a chance to use them much yet but they are similar to others purchased in the past (didn't have the full suit though). Heavy duty and will last with plenty of pockets. It does seem a tad oversized so you could layer underneath, but not huge as some other reviews said. I can comfortably wear it with just a t-shirt or add another layer if need be and I bought L which is the same I wear in other brands although this one came in Tall length as well. Bought for me more for arc flash protection. The fire/arc protection I think basically is some nomex and the zippers are covered. I believe the material is the same as the non-fire rated stuff.
