According to statistics from the EU and World Bank, the textile industry produces synthetic chemicals and dyes that cause almost 20% of all industrial water pollution. Add the estimated 92 million tons of textile waste created each year, and the clothing biz certainly isn't stylish behind the scenes.
Here's the great news, though: you don't need to sacrifice quality and performance for activewear that's produced responsibly. The brands we've picked are committed to producing gear that's ethically made using recycled and natural materials and can also perform at a high level during your toughest rides, gym sessions, hikes and more.
Get ready to sweat with our top picks for men's active shirts.
