I can’t believe I spent years sweating in plastic shorts. Once I switched to Nero’s 100% natural Merino shorts, everything changed. No more chafing or itching. They’re insanely soft, regulate temperature like a dream, and let me focus on lifting instead of adjusting uncomfortable seams. My performance feels better because I’m not overheating or sweating in chemicals. I’m never going back to polyester again.
