Sure, the price may be a little higher (I paid $18 for my own 4-packs), but if you can't find these shirts in your local department store or Walmart, getting them here is a great option.

I wear lots of V-necks in different styles, but I never wear any white ones. Finding these in black and grey were wonderful. The grey ones seem to be a little thicker cotton than the black, but that's better, in my opinion. I wear the black ones as normal everyday shirts, and I actually tie-dyed the grey ones with black and navy blue dyes (and believe me, they are well-suited for that). The Hanes ComfortSoft shirts are the best plain tees I've found on the market right now -- not too thin, not too thick, and very comfortable and durable. If you're a "plain t-shirt" sort of guy, go for it and splurge on these. They may cost a few dollars more, but you'll be able to wear them through hundreds of washings for many years to come.
