10 Top Brands for Men’s Sustainable Jeans & Clothing

There's no denying that sustainable clothing is having a moment. More and more brands are incorporating sustainable practices into their design and production, and consumers are becoming more aware of the impact their clothing has on the environment. A whopping 88% of people want brands to be more environmentally friendly!

Fast fashion has velocity. New styles hit stores at breakneck speed, and we're constantly being tempted to buy the latest and greatest. But this disposable approach to fashion comes at a huge cost - both to our wallets and to the environment. The fashion industry actually accounts for an unbelievable portion of global carbon emissions – more than the entire maritime and aviation industries combined!

As awareness of the impact of fast fashion grows, so does the demand for sustainable alternatives. Sustainable clothing is made from natural fibers that are grown without harmful chemicals, using practices that minimize water usage and waste. Clothing made from sustainable materials is often better for your skin, and can be composted or recycled at the end of its life.

There are a lot of great sustainable brands out there doing amazing things, but it can be hard to know where to start. So we've put together a list of sustainable men’s clothing brands to help you shop more green.

The Environmental Impact of Fast Fashion

Before we look at some of the best sustainable menswear brands, let’s take a look at some of the many ways fast fashion impacts the environment - from wastage to pollution.

Water waste

Denim is made from cotton, which is a water-intensive crop. It can take up to 2,900 gallons of water (just under 11,000 liters of water) to produce just one pair of jeans - the equivalent of bathing in nearly 12 baths! And it’s not just jeans that use a lot of water - the textile industry as a whole is responsible for a great percentage of the world’s industrial water pollution. Many clothing items use synthetic dye, which is water-insoluble. This means that a lot of the dye ends up polluting our waterways and make our water unsafe to drink.

Energy Consumption

The fashion industry is a massive polluter. In fact, it's responsible for 2% of all global carbon emissions. A large portion of these emissions come from the energy required to produce and ship clothing around the world. The growing demand for new clothing has also led to an increase in textile production. Global fiber production is predicted to reach 156 million metric tons by 2030, which is a 43% increase from 2020. This increase in production requires a lot of energy - most of which comes from fossil fuels.


The fashion industry is also responsible for a huge amount of water pollution. The growing of conventional cotton (which is used in around 60% of our clothes) uses more insecticides than any other crop, and these chemicals end up polluting rivers and waterways. Leather production is another major source of water pollution. Leather tanning involves using large amounts of water, as well as toxic chemicals like chromium and formaldehyde. These chemicals pollute local waterways, and the wastewater from tanneries is often dumped untreated into rivers.

Textile waste

Fast fashion generates a lot of textile waste. It's estimated that 5% of all landfill space in the world comes from textile waste, including discarded denim, according to the Environmental Protection Agency (EPA). Once you're done wearing your clothes, they'll likely end up in a landfill where they'll take centuries to decompose. This is why it’s so important to buy sustainable denim, for example, made with recycled materials like organic and recycled cotton.

Labor conditions 

While we’d like to think our clothing comes from fair labor and workers are being paid fairly, labor conditions in the fast fashion industry are often poor, with workers being paid low wages and working in unsafe conditions.

Carbon footprint

Clothing production also has a huge carbon footprint. The growing, harvesting, and processing of natural fibers (like cotton and wool) releases large amounts of greenhouse gasses into the atmosphere. And synthetic fibers (like polyester and nylon) are made from petroleum, which is a major source of greenhouse gas emissions. Most clothing is shipped long distances before it even reaches the consumer, furthering its carbon footprint. The majority is also made in developing countries, where environmental regulations are often lax.

But it doesn't have to be this way! The good news is a number of brands are producing sustainable clothing that are just as stylish and well-made as their conventional counterparts.

Here's our solution - a list of the best men's sustainable fashion brands that are making a difference in ethical fashion.

Best Sustainable Jeans Brands for Men

All of Everlane's denim is constructed with ethical manufacturing processes in certified Fair Trade factories - most of them are their own factory (directly owned) while some are contracted. This means that the workers who make the jeans are paid fair wages, have access to safe working conditions, and can form unions. These ethical factories are clean - recycling water, repurposing byproducts, and more, and they exceed environmental regulations held by other factories in the fashion industry. Everlane's denim is also made with organic cotton, which uses far less water to grow than conventional cotton.
