I purchase these shorts which I really like. They come in many many colors but the thing I found out is that I noticed the pants that I have the very light colored beige or a bit heavier than some of the other match shorts. I wanted to see if all the shorts were completely cotton the white beige pair the light color ones state that the the shell fabric is 100% cotton and the lining is 100% cotton. I purchased these cranberry colored shorts which I like, they seem a bit lighter so I looked at the label it states that the Shelf fabric is 100% cotton but the lining is 100% polyester. I never looked into that before. So far I purchased about 9:00 shorts already plus I purchased the cargo long pants several of those as well. Even though they are polyester inside they are very comfortable but I really rather have cotton especially if it's going to be inside the pants.
