Developed in close collaboration with outdoor enthusiast and photographer Rory Griffin, as well as top Icelandic runners who tested the gear in diverse conditions, the Helgafell collection is designed to perform in environments where the weather is anything but predictable.

Helgafell longsleeve is designed for ultimate comfort and performance when running. Crafted as a base layer for maximum freedom of movement, it features low-profile, stretchable seams and is made from a highly breathable, soft, and stretchable mesh fabric.

Helgafell longsleeve fits perfectly under a lightweight outer layer.
