What Our Gearhead(R) Experts Are Saying:"I brought the Tista Crew Neck Mid Layer Top on a long Nordic ski weekend and wore it three days straight without any odor issues, which tells you everything you need to know about how well the fabric technology actually works. It packs down to almost nothing, and the flatlock seams mean you never feel it under a shell even on the longest days out."Not every layer needs a zipper to earn its place in your kit. The Swix Tista Crew Neck Mid Layer Top keeps things simple and lets the fabric do the talking. Built from a recycled polyester and spandex blend woven with an engineered tech fiber, it resists moisture, controls odor naturally, and blocks UV without any added treatments or coatings. The result is a midlayer that performs well on day one and holds up just as well on day five of a backcountry trip when laundry is not an option. The flatlock seams sit flush against the skin, so there is nothing to irritate on a long effort, and the quick-drying, packable construction means it transitions as easily from a hard skate ski session to an after-ski layer as anything in your bag. Clean lines, reliable performance, and built from recycled materials. The Tista Crew Neck Mid Layer Top earns a permanent spot in the rotation.
