"What Our Gearhead® Experts Are Saying:""I took the Beyond Long-Sleeve Top on a four-day backpacking trip and it held up better than anything else I packed. The reinforced shoulders and lower back made a real difference under a loaded pack, and the Polygiene treatment kept it genuinely fresh well past the point where my other layers had given up.""Day two on the trail and the pack is still heavy, the elevation is still climbing, and the Beyond Long-Sleeve Top from La Sportiva is still doing exactly what it was built to do. This is the shirt for the kind of trips where you cannot afford to carry extras and every piece in your kit needs to earn its weight. La Sportiva constructed this top from 100% recycled polyester with wicking properties that pull moisture away from the body and keep you from that cold, clammy feeling when the effort crests and the breeze picks up. Reinforced paneling at the shoulders and lower back takes the daily punishment of a loaded pack without breaking down over a long trip, and mesh underarm inserts keep airflow moving through the hardest sections of trail. Polygiene antibacterial treatment means this shirt stays fresher than it has any right to after multiple days of hard use, which is exactly the kind of performance that earns a permanent spot in the pack."
