What Our Gearhead(R) Experts Are Saying:"This shirt is my go-to for hot, sunny days on the move. It breathes well, doesn't cling, and the fold-up collar gives me extra neck coverage when things heat up. It's great for travel too-packs down small and still looks sharp after a long day out."When the days are long and the sun is high, the Salathe Sun Short-Sleeve Shirt keeps us cool, protected, and adventure-ready. Royal Robbins designed this versatile short-sleeve button-up for breathability, comfort, and movement, using 100% recycled polyester in a relaxed fit with extended shoulders for dynamic mobility. It's a staple for hiking, travel, and laid-back mountain town days. With a fold-up buttoned collar for added coverage and a shirttail hem that stays put when we're on the move, this shirt is built for high-output days in exposed terrain. Lightweight and highly breathable, it's the kind of layer we can wear straight from the trail to town-especially with the subtle, heritage-inspired prints that bring a little extra style to every mission.
