This item is so popular that it's hard to keep in stock. At first, only a few of the colors were available, but now we've got all the colors for the TRU Combat Shirt listed in the store.
I might just get one in each color for myself, because these shirts are so comfortable and wearable in so many different environments. The Cordura base layer fabric is soft and breathable, which makes it great for layering underneath a vest, while you still have the sleeve features of a conventional uniform. If you wear a vest all the time, you could easily swap out your old uniform shirt for this one. Or, it looks good on its own, for a more modern look.
