Men’s activewear with a conscience

There’s no denying that the ethical fashion world is long been geared towards women or femme-presenting people. Things are changing slowly, and there is now a whole host of brilliant brands for those who prefer to wear menswear, but the reality is that activewear options are still a bit limited. That’s because sports gear often adds an extra layer of complexity to sustainability thanks to the amount of harmful chemicals and synthetic fibres that are so prevalent in conventional activewear. They’re used for their helpful properties, like durability, stretch, and water and wind-resistance, but the impact of such chemical treatments and fossil fuel-based materials far outweighs any positive characteristics they might have for sports.

Thankfully, there are some more sustainable brands specialising in gym, yoga, hiking, training, and swimming menswear, and we’ve listed them out below along with our top picks. They include brands opting for lower impact materials such as bamboo, TENCEL, organic cotton, or more ethically sourced merino wool instead of synthetics. There are also recycled polyester options too, in place of virgin fibres.

A note on degendering fashion

While this article may be addressing keywords on men’s sports and activewear, the fact is that clothes don’t have any gender. It sometimes seems silly how the industry ascribes gender to inanimate garments like t-shirts and socks. We believe people of all genders should be able to express themselves however they want, regardless of the binary marketing. So when you use our directory to search for brands, we automatically deliver search results without any consideration to gender. If you still want to find products labelled as menswear or womenswear, you can use our filters.
