Blue collar workers's first pick: Imagine you have to work hard all day, loading heavy things, driving for hours, you don't want to wear a shirt that traps all the sweat which can make you feel very uncomfortable, itchy and sometimes smell bad. 

Tuco shirt is made from 100% polyester, it's breathable & water-repelling , pushing all the moisture toward the outer layer where it can evaporate.

Perfect choice for tactical enthusiasts: It's also very durable & stretchable in case you carry heavy gears like body amor or chest rig that come up over the top over your shoulder, it wouldn't suffocate and wear you out like a heavy, bulky BDU type shirt would.

Its high & tough collar protects your neck: If you own a shotgun or rifle, Tuco shirt's high collar helps protect you against theirs slings from shaking your neck. Also, if you're in a one or two-week ruck march or on a backpack hunt, you need a good high-collar combat shirt to prevent your neck from being "over-rubbed".
