What Our Gearhead® Experts Are Saying: "I like this shirt for warm days when I want something breathable but still put-together. It’s lightweight, layers easily, and the shoulder design makes it comfortable under a pack." We button up the Viken Short-Sleeve Shirt and head out for warm-weather adventures that move from trail to town without missing a beat. Helly Hansen blends laid-back style with practical performance, making this an easy go-to for everything from casual hikes to travel days. The lightweight cotton-poly blend keeps us cool and comfortable, while the no-shoulder-seam design reduces pressure points when wearing a pack. A classic button-up front and chest pocket give it everyday versatility, while the all-over print adds a subtle touch of personality. Easy to wear on its own or layered, this shirt is built for wherever the day leads.
