What Our Gearhead(R) Experts Are Saying:"I put the Beyond Long-Sleeve Shirt through a full day of switchbacks with a loaded pack and it held up exactly how I needed it to. The Polartec(R) Delta(TM) fabric did a real job of moving moisture away during the climbs, and by the time I hit the ridge the shoulders showed zero signs of wear from the straps. Three seasons in and this is my default hiking layer when the temperature starts to drop."Cool morning air, a loaded pack, and a long ridgeline ahead. The La Sportiva Beyond Long-Sleeve Shirt is the piece you grab on those days when the forecast is uncertain and the mileage is not, built to manage heat and moisture as the trail pitches upward and the effort compounds over hours. La Sportiva engineered this shirt around Polartec(R) Delta(TM) fabric, a specialized construction that pairs hydrophobic and hydrophilic yarns to pull moisture away from the body and push it outward where it can evaporate. Mesh inserts at the underarms and sides keep airflow moving through the hardest climbing sections, while reinforced paneling across the shoulders protects against the slow abrasion of a shoulder strap grinding through a full day of miles. Reflective details mean the shirt keeps working even when the light drops on the back half of a long push. Everything here is built with intention, and the recycled materials running through the construction mean the trail you are hiking stays worth hiking.
