Look for 100% polyester or poly-nylon blends with mechanical stretch. Moisture-wicking treatments like Polygiene® and mesh ventilation panels enhance breathability. Flatlock seams prevent chafing, while UPF 30+ ratings add sun protection for prolonged exposure.

Merino wool blends (15-20% wool) or polyester with antimicrobial treatments combat bacteria growth. Loose weaves enhance airflow, while wrinkle-resistant fabrics maintain freshness between washes - ideal for multi-day trips.

Raglan designs allow full shoulder mobility without restricting arm movement. Look for shirts with underarm gussets and four-way stretch fabric for climbing, kayaking, or backpacking.

Strategic mesh panels (back/underarms), laser-cut ventilation holes, and lightweight fabrics (under 150gsm) enhance airflow. Darker colours with UPF coatings provide sun protection without trapping heat.

Yes - convertible roll-up sleeves, quick-dry fabrics, and chest pockets make them versatile. Look for hidden button snaps on collars for sun protection and abrasion-resistant shoulders for backpack straps.

Wash in cold water with non-detergent cleaners like Nikwax Tech Wash. Avoid fabric softeners that clog fibers, and line-dry to preserve antimicrobial treatments and fabric elasticity.
