The Summit Fever High-Country Tank

The peaks of the Olympic range have a way of getting under your skin, a magnetic pull toward the jagged skyline that some call madness and others call home. The Summit Fever High-Country Tank is built for those high-output days when the only direction is up. This premium mid-to-heavyweight top is constructed from 5.5 oz soft-washed, 100% combed ring-spun cotton, providing a structured yet exceptionally smooth feel that stands up to the grit of the trail. The tight-knit, durable material ensures longevity through seasons of scrambling over basalt and cedar deadfalls.

Designed for maximum breathability during the final, sun-exposed ascent, the sleeveless drop arm and relaxed fit allow for total range of motion and essential airflow. Whether you are using it as a moisture-absorbing layering piece under a rugged flannel or wearing it as a standalone workout top, the extra soft surface keeps you focused on the next handhold rather than your gear. While the Athletic Heather and Charcoal Heather options introduce a performance-minded blend of cotton with viscose or polyester, every version maintains the rugged, soft-washed comfort Kairnu demands. When the fever takes hold and the summit is in sight, this is the layer that moves with you.
