The Ibex Men's W2 Sport 12 Zip Long Sleeve T Shirt outperforms all synthetic layers with its Weightless Wool fabric. Blending lightweight merino wool with nylon, this ultra tough material is super soft for hours of luxurious comfort. Since merino wool naturally fights odor, this performance layer won't leave you smelling foul. Working well as a standalone piece for warm weather exercise, this long sleeve performance tee pulls moisture off your body. In addition, it's a great base layer on cool and downright frigid days when you're exercising outside. Enhanced ergonomics come courtesy of a semi fitted design and half zip closure.
