Choose Your Colour
Blue
Mid-indigo denim in an 11oz weight — heavy enough to hold its shape, not so heavy it reads as workwear.
Black
Straight black denim. Goes anywhere the bike doesn't — nobody reads it as riding gear.
Select your colour and size using the pickers above before adding to cart.

A women's cut, not a men's jean in a smaller size.

The Motrox Sierra is cut slim and straight through the leg on a women's block, in an 11oz stretch denim that keeps its shape over a long day rather than going baggy at the knee.

The protection is the same standard as the rest of the Motrox denim range: Kevlar® panels reinforcing the seat and knees, and CE certified knee and hip armour already fitted inside the pockets when it arrives. Nothing to buy separately, nothing to work out.

Key Features
Key Features
Kevlar® Reinforced Panels
Aramid Kevlar® panels reinforce the seat and knees — the areas that make contact first and hardest in a slide. Panel composition: 52% aramid Kevlar®, 48% polyester.
✓
CE Certified Armour — Fitted Before It Ships
Knee and hip protectors come already seated in the internal pockets. Most riding jeans leave that job to you, or leave the armour out altogether.
✓
11oz Heavyweight Stretch Denim
97% cotton, 3% elastane. Substantial enough to sit properly with armour in it, with enough give to move naturally.
✓
Slim Straight Women's Fit
Cut on a women's block — shaped through the waist and hip rather than scaled down from a men's pattern.
✓
Accordion Stretch Panels
Flex zones at the knees and lower back — the two places a riding position pulls hardest.
✓
Secure Cargo Pockets
Double snap closure, so nothing works its way out at speed.
✓
YKK Hardware
Heavy-duty YKK zips throughout — the part that fails first on cheap riding denim.
Construction
✓Outer: 97% cotton / 3% elastane
✓Kevlar® panel: 52% aramid / 48% polyester
✓11oz heavyweight stretch denim
✓CE certified knee & hip armour included
✓All armour fully removable
✓Accordion stretch at knee & lower back

Why The Sierra
Why The Sierra
👗
Cut For Women
Shaped through the waist and hip, not a unisex jean with a different label on it.
📦
Nothing To Set Up
Armour arrives in place. No hunting for the right inserts, no guessing which pocket takes what.
⚙️
Armour On Your Terms
Keep it in for the ride, pull it out for the wash. Two zips and it's done.

⚠️ Sizing Tip — Please Read Before Ordering
Take a tape to your waist rather than going off the label in your current jeans — denim stretches with wear, so an old pair usually reads a size small. If you fall between two sizes, take the larger one — armour pockets sit closer to the body than plain denim.

Care & Important Notes
🧺
Washing: Machine washable. Remove all armour inserts first, then follow the garment label. Washing inside out and cold helps both colours hold their depth.
🔧
Removable Armour: Knee and hip protectors arrive fitted and are fully removable via the internal zip pockets.
🎨
Colour Accuracy: Slight colour variation from the listing photos may occur due to screen and photography lighting.
Protective riding denim cut for women who actually ride.
