Overall, others give this:
I purchased these for my son and Hanes has made adorable, light, high quality shirts. As another reviewer has mentioned, the shirts are also excellent for the summertime.
These white tanktops aka a-shirts are great. My 4 yr old nephew wears these all the time in summer and under shirts and hoodies in the winter. A bit pricey for tanktops but its worth it because they last a long time. Kmart and Sears always have good selections of these.
