To use this Brunt men's black pocket T - shirt, simply put it on like any regular T - shirt. It's great for everyday wear, whether you're working hard or just relaxing. When it comes to washing, use cold water in the machine. Avoid using hot water as it may shrink the fabric. After washing, you can tumble dry on low. Try not to iron over the custom BRUNT print on the sleeves to keep it looking sharp. Also, make sure to empty the chest pocket before washing to avoid damaging the hidden pen holster.
