12 Top Sustainable Sweaters For Men in 2023

October 21, 2022main

It appears we’ve officially entered sweater season yet again! For seekers of cozy, wool, cashmere and organic cotton sustainable men’s sweaters are the holy grail of eco-friendly fibers. Because let’s face it; there’s nothing better than a warm, extremely soft knit to snuggle in while you venture out in the gloomy outdoors. It’s no secret that sustainable sweaters for men are a true investment. However, not all luxurious knits are created equal –or ethical. 

 Wool production uses heat, water, and chemicals. On top of that, microfibers from synthetic fibers heavily contribute to plastic pollution in the world’s oceans. Let’s not forget that sheep are mutilated, abused, and skinned alive all in the name of fashion. These are only a few reasons why it’s so important to choose ethical and sustainable men’s sweaters that have been vetted and approved by third-party organizations.

Luckily, there is an influx of luxe options rendered with responsibly-sourced wool, recycled material, and organic cotton ready for grabs. Our most trusted ethical menswear brands below are lauded for their fantastic lines of Fair Trade, consciously-produced sustainable sweaters for men. Some employ skilled artisans from developing countries to handcraft their knits while others give back in a slew of different ways. One thing is certain; your quest to find the best men’s sustainable sweaters ends here.
