What’s the most hardworking item in your wardrobe? For me, it’s my jeans. A true workhorse, is there anything that jeans don’t go with?

Well, actually, do jeans go with sustainability? Are the two words mutually compatible? There’s a lot wrong with a standard pair of jeans. Let’s take a brief look, before looking into my guide to ethical jeans and denim.

What’s Wrong With Conventional Denim?

Jeans are one of the most commonly bought items of clothing in the UK. However, making a pair of conventional jeans is a dirty business. From the environmental and social impact of growing cotton inorganically to the vast amount of water that it takes to make a single pair of jeans, right through to the associated water pollution.

However, these aren’t the only impacts that the denim industry has. Sandblasting jeans, to create a lived-in look can cause the deadly lung disease silicosis in workers who are involved in sandblasting. Meanwhile, synthetic indigo dyes use chemicals known for their toxicity. These include formaldehyde and hydrogen cyanide. Conventional denim is far from ethical.

BAM: Bamboo Clothing

Price: ££

Fits: Waist sizes 24 – 36 inches in regular or long lengths

Gender: Male and female styles available

BAM’s supersoft jeans*, for both men and women, are a great sustainable choice of jeans.

Made from a blend of organic cotton and bamboo, so your jeans are soft and comfortable, BAM says these jeans use 74% less water than the average pair of jeans to manufacture. Bamboo as a fabric can be problematic, but I’ve written here about BAM’s careful manufacturing processes.

Because of the rivets and hardware on conventional jeans, only the legs of conventional jeans can be recycled. What makes BAM’s jeans a great eco choice is that they’ve developed them in line with the Ellen MacArthur Foundation Jeans Redesign to be environmentally friendly. Therefore, BAM’s jeans have no rivets. They also have an un-screwable button. This means that once the zip is cut out then BAM jeans can be fully recycled for denim with less waste.


Beyond Retro Ethical Jeans

Price: £ – ££

Fits: XS – XXL

Gender: Male, female and unisex styles available

Beyond Retro’s huge range of preloved denim* makes it a great one-stop shop for all your sustainable denim needs. With every wash, size, colour, and style imaginable – from jeans to dungarees, as well as shorts, skirts, shirts, and jackets – you are sure to find the perfect addition to your wardrobe.

When it comes to jeans, Beyond Retro has a filter so that you can specifically look for high-waisted jeans, flared jeans, vintage Levis, and more. Handy!

What’s more, Beyond Retro also has dedicated plus-size sections for both men and women, catering up to size XXL. There is also the ability to search for unisex jeans.

Use the exclusive code MORALFIBRES at the checkout to receive 15% off your order at Beyond Retro.

The Hemp Shop Co

Price: ££ – £££

Fits: men’s 30 – 36 inch waist; women’s 26 – 28 inch waist

Gender: Male and female styles available

If you are specifically looking for hemp jeans, then head to The Hemp Shop Co*. Made from super sustainable hemp and certified organic cotton, these jeans also ship plastic-free.

What makes hemp a sustainable fabric choice is that hemp does not need any toxic chemicals such as fertilisers or pesticides to grow. It also returns around 60% of the nutrients it takes to the soil, helping to maintain good soil health. Hemp also requires very little water to grow. It’s little wonder hemp is one of the most sustainable fabrics available.

The women’s range has very limited sizing available, however, the men’s range is much more accommodating. With a wider range of waist sizes and multiple leg size options, I would say The Hemp Shop is best for men looking for ethical jeans.


Hiut Ethical Jeans

Price: £££

Fits: 25″ to 40″ waists in a variety of leg sizes

Gender: Male and female styles available

Hiut ethically makes beautiful bespoke jeans, handmade in Cardigan.  These are expensive jeans, but whilst the initial outlay might be high, expect a pair to last forever.  Hiut stands by their jeans even when they fail you. As such they offer free repairs for the life of your jeans, with just one rule. You have to send them back washed. I think that’s fair enough!

Made from a mix of recycled cotton, and standard cotton these jeans are not organic. However, ethical considerations have been made. As such, 100% of the water Hiut uses is recycled, and no harmful chemicals have been used in the treating of the jeans.

Do note, that these jeans have a leather patch on them, so are not vegan-friendly.


Howies

Price: ££

Fits: men’s 30S to 38L / women’s 26R to 34R

Gender: Male and female styles available

Looking for organic jeans in a variety of fits and colours? Try Howies. They stock a variety of GOTS-certified organic jeans for both men and women. What’s more, their jeans are OEKO-TEX certified as being free from hazardous chemicals.

As well as being designed for the perfect fit, they are also designed to last. As such, their jeans are reinforced at key stress points for extra durability.

I’d say that Howies is best for men. The men’s range comes in 8 different waist sizes, and 3 different leg lengths. The women’s ethical denim range comes in 6 different waist sizes, but only a standard regular length. This isn’t ideal if you are petite or tall.


Kowtow

Price: ££ – ££

Fits: XS – XL

Gender: Female styles available

Kowtow’s denim trousers* are made from 100% organic cotton chambray. This is dyed with Global Organic Textile Standard (GOTS) approved inks and dyes. This means they are free from chlorine bleach, toxic heavy metals, formaldehyde, and aromatic solvents.

Kowtow’s ethical denim is made in a transparent supply chain, which works with fair trade certified farmers and manufacturers from seed to garment.

And for vegans, I have good news. The trousers are finished with recycled hemp buttons made in Italy – there are no animal products here! 


Monkee Jeans

Price: ££

Fits waist sizes 24″-36″

Gender: Male and female styles available

Monkee Genes* are purveyors of organic bamboo or GOTS certified organic cotton jeans, made in England, that are beautifully soft.  

With a zip fly fastening these full-length jeans have waistband patches made from a special material called Jacron. This is a unique paper material with a leather-like look. However, it is vegan and is a sustainable alternative to plastic or leather patches.

If it is black jeans that you are looking for, then Monkee Genes have been produced using a special process that means that they will stay blacker for longer.

My only gripe is that Monkee Genes only come in two leg lengths – regular and long.  The regular leg length is 31″, so if you’re on the shorter side you may struggle with the fit.


MUD Ethical Jeans

Price: £££

Fits waist sizes 26″-36″

Gender: Male and female styles available

MUD Jeans* make jeans from organic cotton and recycled denim. This helps to avoid waste and cuts down on water and CO2 use.  At the moment their jeans contain 40% recycled denim.  However, keep an eye out as MUD aim to launch the first jeans made from 100% post-consumer recycled denim. 

Rather than washing the jeans to create the wash, they use innovative ozone and laser processes. This cleverly reduces the amount of water used to manufacture a pair of jeans by up to 75%. This also helps to reduce water pollution.  

What’s also to love about MUD, is that jeans labels are printed instead of using leather. This means that their entire jeans range is cruelty-free and suitable for vegans.

What’s more, Mud takes back your old jeans once you are done. Here they will either sell them if they are in good condition. If not, they will recycle them by blending them with organic cotton to create new jeans for a more circular approach to denim.


Nudie Jeans

Price: £££

Fits sizes 24″ to 38″

Gender: Male and female styles available

Nudie’s 100% organic and vegan-friendly jeans* are made ethically in Italy with sustainability in mind.  

What I especially love about Nudie jeans is that they’ve considered longevity. So if your jeans need mending you can pop into their London shop to take advantage of their free repair service.  And don’t worry if you are not London-based, they can send you a repair kit free of charge.  And once your jeans are finally worn out, you can send them back to Nudie and they’ll recycle them into new jeans. You’ll also get 20% off your next order.


Organic Basics Ethical Jeans

Price: £££

Fits: waist size 26 – 36

Gender: Male and female styles available

Danish-based Organic Basics jeans* are produced only using organic and recycled cotton. They don’t use any synthetic blends so that their denim can be fully recycled and stay in circulation for longer. From what I understand, Organic Basics are also looking at introducing a recycling scheme for their denim.

As well as zero synthetic blends, Organic Basics takes sustainable and ethical production seriously. From a commitment to fair wages, zero-waste production, and solar power energy, they make for a great ethical denim choice.

Whilst their jeans come in a variety of colours, my only gripe with Organic Basics is that they only offer one leg length. This means if you are shorter or taller, then it will be tricky to find the perfect fit.

Use the exclusive discount code WENDYOBC at the checkout for 10% off your order.


Oxfam

Price: £ – ££

Fits: XS to XXXL

Gender: Male and female styles available

Want to shop for affordable ethical and sustainable jeans and support a charity at the same time? Then look no further than Oxfam Online*. They have a great range of pre-loved denim, for men and for women, in a vast array of sizes, styles, and colours.

Delivery is also just £3.95, no matter how many items you order.  For extra peace of mind, returns are free.  You also get the added bonus that your purchase is supporting a good cause – all profits go to supporting Oxfam’s work in alleviating global poverty.


Patagonia

Price: ££ – £££

Fits 26 – 40 inch waist

Gender: Male, female and unisex styles available

Patagonia’s ethical jeans* are Fairtrade certified. This means that as well as paying the Fairtrade premium, to ensure producers are paid a fair price, Patagonia pays an additional premium for every Patagonia item that carries the Fair Trade Certified™ sewn label. That extra money goes directly to the workers at the factory, and they decide how to spend it.

Here workers have chosen to use the premiums to fund community projects, like health-care programmes or a child-care centre, or to purchase products they could not otherwise afford, like a laptop computer or a stove; or to take a cash bonus. 

What’s more, Patagonia’s ethical denim is designed to last and be repairable.  Their website also gives advice on how to repair all Patagonia items, which is seriously useful.  And for any clothing that can’t be repaired then you can drop it off at a Patagonia store for recycling or repurposing. 

People Tree Ethical Jeans

Price: ££ – £££

Fits UK sizes 8 – 16

Gender: Female styles available

Made from 100% GOTS certified organic cotton, People Tree’s ethical denim collection* saves up to 90% of water during the production process, compared to conventional denim production.

People Tree says their organic cotton is grown using methods and materials that have a low impact on the environment. What’s more, they have systems in place to replenish and maintain soil fertility, reduce the use of toxic and persistent pesticides and fertilisers, and build biologically diverse agriculture.

And as the People Tree branded back patch is made from washable paper, this means their denim collection is vegan-friendly.


Rockit

Price: £ – ££

Fits: XXS to XXL

Gender: Male, female and unisex styles available

For preloved ethical denim, Rokit* is another great online retailer to check out. From the 1930s to 2010s vintage denim, Rokit stock a wide range of styles, colours, and washes of jeans for men, women, and children, as well as unisex styles. And with a vast inventory (at the time of writing there were 963 pairs of jeans listed), covering sizes XXS to XXL, Rokit’s size inclusivity is something to applaud.

Never bought preloved jeans? Don’t worry, every item is cleaned and pressed before being added to Rokit’s webshop. This means you won’t get any nasty surprises when your jeans arrive.


Thought Ethical Jeans

Price: ££

Fits: UK sizes 6 – 20

Gender: Female styles available

Thought’s range of eco-friendlier jeans and denim* are ethically made in Turkey from GOTS-certified organic cotton. What’s more, all of their denim is also OEKO-TEX® certified. This means that every component of their jeans – right down to the thread and buttons – has been tested and is free from harmful substances. So you can be assured that Thought’s jeans are made in a chlorine and toxic chemical-free wash.

Even the patch is leather-free, making these jeans vegan-friendly.

How to Make Your Jeans Last Longer

The most sustainable and ethical jeans are the jeans you already own. Thankfully there are some useful tips to keep your jeans in wearable condition for longer.

Laundry

How you wash and dry your jeans can make a huge difference to how long your jeans last. Here’s my laundry best practice for jeans.

Washing

Try to wash your jeans only when they need washing. In my guide to how often should you wash your clothes, it’s recommended that jeans should be washed after 4 to 5 wears. Minimum. Of course, if they are dirty or smelly, then wash them. But if not, and you are not used to washing jeans so infrequently, and are self-conscious about smelling, then do so incrementally. After day 2, see how you feel about stretching to day 3. And so forth. You can do it, I believe in you!

When you do wash your jeans, wash them inside out. Turning jeans inside out when you wash them helps protect the outside of the jeans from friction and direct exposure to detergent. Both of these actions help prevent fading, making your jeans look better for longer.

Drying

Avoid the tumble dryer if you can. Heat can shrink or fade denim, and it can also cause damage to stretch denim fabrics. The best way to dry jeans is by hanging them up to air dry. If you do need to use a dryer, select a low or no heat cycle and use dryer balls to keep your jeans tumbling. Remove the jeans while they’re still slightly damp, then stretch the seams and hang them up to finish drying. By not over-drying jeans, you help avoid shrinkage and damage to the fabric.

In A Fix

Life happens. Your jeans might develop a rip or a tear. Instead of binning them, you can leave the rip or tear as is, and allow your jeans to develop a bit of character. The alternative is to fix your jeans.

If you’re not handy with a needle and thread, a tailor will be able to mend your jeans for you. If you do know your way around a sewing kit, then jeans can be patched up in a variety of ways. From patches to visible mending, to invisible mending. YouTube has a great selection of ways to mend your jeans.
