The Tobias short sleeve shirt is exclusive to our Dragon Collection. It is made of extrafine merino wool jersey, which makes it super lightweight. Perfect for those hot summer days. Don't let the "merino wool" scare you; the properties of this fabric make it delightfully soft due to it's fine fiber and has natural stretch. It is also moisture-wicking, which means it moves moisture away from the body and repels it. This knit shirt has a button down collar- a perfect combination of causal yet refined. This shirt has it all- trust us, you will fall in love.
