The soft and comfortable zip neck is a versatile classic that you can use as a mid-layer on cold winter trips or as an outer layer on top of a sweat-wicking base layer. The shirt is designed with a half-high collar and a short zipper, so you can adjust the collar according to the weather and your style. This zip neck is made of our elastic and sweat-wicking C3 material, which makes it quick-drying, breathable, and durable. You can also use your C3 Zip Neck on your way to/from your workout, warm-up, or for outdoor activities and relaxation. The shirt is soft and comfortable. It ensures quick and good sweat transport, so you never get cold and damp, either during or after activity.
