I have to where a suit everyday to the office. I am currently working in West Africa, where it is either hot and dry or hot and wet, depending on the season. So, I sweat like everyone else and therefore I wear a t-shirt everyday. This has been going on for years and I've go through dozens and dozens of t-shirts. But lately I have gone back time and again to Jockey slim fit cotton stretch t-shirts, for two reasons. First, they fit very well. The elasticity of the shirt allows it to hug your body in a comfortable way and leave no seam or wrinkle under my dress shirts. Secondly, they are a sturdy shirt. They go through some pretty rough washing and they come back clean and still holding their shape time after time. A very good product made from reliable fabric and sold at a reasonable price.
