I had bought 5 very light grey shirts years ago to act as undershirts when I needed something other than white.  They were showing their age and I decided to replace them with these.  Very good decision as they're sturdy without being heavy, they're a nice light neutral grey color, and I actually think it's a bonus that they're the slightest bit larger (maybe the old ones shrunk?).  I expect they'll only turn even softer and lighter with use which is perfect for me.
