The Smartwool® Osa Vega Short Sleeve Graphic Tee blends casual style with serious tech. Made for movement, its regular fit gives you room to groove without the bulk, while set-in sleeves and a ribbed crew neck amp up the comfort. This tee pulls on effortlessly and works hard behind the scenes-thanks to a fabric that wicks moisture, regulates temperature, and resists odors. Short sleeves keep it breezy, while the stepped hem with side slits boosts mobility.
