Some training sessions begin without a layering plan, and the Swix Tista 1/2-Zip Midlayer works alone or under a jacket either way. Its stretch knit moves with the body, a thumbhole cuff keeps the sleeves in place, and flatlock seams make the fit comfortable. A half-zip neckline finishes this long-sleeve midlayer. What Our Gearhead(R) Experts Are Saying:"After a hard effort and a stop for an after-ski break, the fabric had already dried by the time I zipped my jacket back on. The knit wicked moisture away during the effort, so the top stayed comfortable under the jacket."
