Black Denim

Our active jeans now in a straight leg and two leg lengths. These sustainable jeans prove style can be planet-friendly – the button even unscrews to make them easier to recycle (so screw in tightly before washing).

We recommend you order a size smaller than usual.

Our active women’s jeans now come in a high waist with a straight leg that looks great rolled up. They still have a little stretch to flatter your shape perfectly.

We’ve developed them in line with the Ellen MacArthur Foundation Jeans Redesign to be environmentally friendly. We’ve used organic cotton and bamboo as it needs no additional irrigation, saving thousands of litres of water. Both the black and deep indigo colours have a classic feel but the choice of colour means the fabric doesn’t need to be bleach washed. Even the button unscrews to make recycling easier.

73% of clothing ends up in landfill. We’re determined to get that down to zero. Hence the name: 73 Zero. Click here to find out more about 73 Zero jeans.

These jeans come up large so we would recommend you order a size smaller than usual.

  • Regular Length Inseam – 73cm
  • Long Length Inseam – 78cm



73% Organic Cotton, 25% Bamboo Viscose, 2% Elastane.

Supersoft and made for action.

Our denim is made from an organic cotton and bamboo blend so it's incredibly soft and comfortable. Put it through its paces, this denim has enough stretch for you to scale a rock face. It's sustainable too, needing 74% less water than conventional denim.

Soft material and good fit
Annie Wissmiller - Tuesday, 26 July 2022
Love the waist and the length was perfect - I'm 5'10" and they hit nicely above the ankle. They do seem to have a bit of extra fabric for me in some places, but I prefer that with the comfort it comes with. Love the fabric, especially the recyclability.

These just didn't suit me but returned and received a refund with no issues

I already have a pair of these in blue but standard leg length, which is great when standing (so great walking, shopping etc) but a little short when I sit so I got a black pair in long length and these are great for meals our and visits to people and places but I still wear the shorter blue pair sh...

Lovely feedback!
Mary Elisabeth Arnold - Thursday, 23 June 2022
These jeans are very soft and comfy and totally non-irritant. I usually wear a size 8, so couldn't go any smaller, as recommended, but the fit was the best I have found in jeans, sitting on the waist, just the right leg length, and wide enough at the cuff to get on easily over my big feet! And how g...

Enjoy your new BAM jeans!👖
Trusted Customer - Thursday, 26 May 2022
These are genuinely the best fitting jeans I have ever spent money on. I've got short legs with narrow hips compared to my waist so I've always struggled to find something flattering but these are amazing. I love that the waist goes up in 1 inch increments rather than the usual 2 and there are a cho...

These are really comfortable jeans and as it said on the page, very roomy so possibly order a size smaller.

Nice material, comfortable but slightly shapeless in upper leg - debated whether to keep or return tbh but decided to keep as husband thought they looked ok!
