I bought my shirts for work. I run Central Receiving for the school districts in my area. Working in a warehouse you experience different types of conditions, heat, cold, dust etc.. I needed a work shirt that wasn't too heavy & not too light either. The Beefy T fit the bill. It's heavy enough that you can actually wear it during colder month's and light enough when things heat up you don't sweat to death. I have mine with the pocket to hold pens & markers. Ordering was a piece of cake and shipping was super fast! If you're looking for a reliable T-shirt..You can't go wrong with Jiffy.
