9 Sustainable Men’s Swimwear Brands

The weather may not be the most summery, but it sure makes us long for sunshine, and gets us ready to hit the beach – in our ethical swimwear of course!

Summer is coming… the call of the ocean is getting louder and louder.  Of course, the ocean has not been far from our minds, with reports of the plastic pollution pandemic never far from public consciousness.  Amongst those working to clean up our seas are an increasing number of ethical swimwear brands that are using recycled and recyclable materials for their products, as well as supporting ocean cleanup charities in the process. 

Here are some of our favourite men’s swimwear brands with a conscience:

United by Blue

United by Blue is radically combatting waste inherent in the production supply chain, with a pledge to completely erase its usage of single-use plastics by 2020. In addition, for every piece bought, United by Blue removes a pound of trash from the sea, a commendable commitment which has so far removed 1,756,888 pounds of trash from our oceans!  United by Blue is so impressive because it really recognises how we all contribute to the plastic pollution crisis, but also how together we can really make a difference to prevent the waterfall of plastic into our oceans.
