Lenni Long-Sleeve Shirt—lightweight, quick-drying, and ready for the trail

What Our Gearhead® Experts Are Saying:


"I’ve worn the Lenni Long-Sleeve on everything from warm-weather hikes to sunny climbing days. It’s lightweight, dries super fast, and the HeiQ Fresh tech keeps it from getting funky after long hours on the move."


We’re out there for the long days—trekking through thick forest trails, catching glimpses of sun-dappled ridgelines, and watching the horizon come to life as the clouds part. With the Lenni Long-Sleeve Shirt, we’re never held back. Crafted with a lightweight, quick-drying fabric, it’s our favorite piece for everything from easy day hikes to remote alpine tours.


The recycled polyester blend keeps us moving freely, and the HeiQ Fresh treatment means even after a long day, we’re still fresh and ready to push further. A chest pocket for essentials, a movement fold for flexibility—it’s all in the details. Versatile, reliable, and always ready for the next step.
