These are basic t shirts.  Fairly lightweight, reasonably soft but have no stretch.  They shrink slightly in the wash, and fit fairly close to the body for a given size (so if you want them loose, size up).  These are more for wearing under another shirt (or for lounging around) than as a sole t shirt.  They are about average length, if you have a long torso you may find these too short.

They are an excellent value at this price.
