Why we made it

Designed to be as versatile as they are sustainable, our GAIA Jeans are perfect for both climbing escapades and daily wear. Relaxed tapered leg.

Embrace the dynamic 4-way stretch, the comfort, and the durability of one of our favourite jeans. Wear them, love them, and live in them, they're basically like denim sweats!

Our new Eco-MORPH 3.0 denim is made with organic cotton and features a super stretchy waistband and our signature diamond cut crotch means you can get your leg over your head if you so wish 😉 

Why you'll love it
  • Tailored to a relaxed tapered leg
  • Made with organic cotton & lyrcra for stretch
  • 4 well sized pockets - 2 on the front and 2 on the bum
  • Our signature diamond crotch for a full range of motion
  • ECO-GREEN 'waterless washing' system does exactly that, alongside reducing energy use and pollution levels to give you this classic retro wash
  • No animal products used + a FSC certified recycled card jeans patch
