The Colturi Sirio Top is your go-to for high-output days on the trail or at the crag—where technical performance meets bold design. More than just a tank, this sleeveless technical tee blends lightweight breathability with a streamlined, backpack-friendly fit.

Crafted with two ultra-light fabrics, the Think 44 mesh in the printed panels offers active ventilation, while Coolwave side panels enhance stretch and moisture management. The wide shoulder straps minimize pressure points under a pack, and the shallow neckline reflects its performance-focused roots.
