The Apex Leggings
Whether you’re trekking through mangroves, kneeling on a boat deck for samples, or just powering through your daily workout — the TSL Field Leggings have you covered. Designed with scientists and explorers in mind, these leggings combine comfort, durability, and UPF 50+ sun protection so you can focus on the work (or adventure) at hand.
Crafted from a smooth microfiber yarn with four-way stretch, they move with you — no matter if you’re climbing, crouching, or chasing after the next discovery. The elastic waistband and reinforced stitching add reliability, while the eco-conscious, made-on-demand production means every pair helps reduce waste.
Why You’ll Love It:
Stylish enough for everyday wear, tough enough for fieldwork
UPF 50+ for sun-safe days outdoors
Flexible stretch fabric that never loses its shape
Smooth, durable finish that stays comfortable all day
Built for science. Worn for adventure. Powered by you.
