I don't normally do posts on military shirt makers, but Grunt Style LLC has some really sweet designs.
Their Basic Tee is priced at just $12.95 each. And based on customer reviews, the quality seems to be unusually high.
Grunt Style offers conservative as well as over-the-top designs -- most with patriotic or warfighter themes. The Illinois-based shop also makes hoodies, polo shirts, beanies, patches and other novelties.
Tim Jensen, company 1st Sgt. at Grunt Style, is pretty entertaining too. Check him out in the promo video.
