Why we made it

We’ve taken one of our favourite silhouettes and brightened it right up! Add fun to your adventure with our Gaia twills 😜

Our Gaia jeans have been labelled as “denim sweatpants” because they’re so comfortable 🤗 and the same goes for our Gaia twills - you really won’t believe how comfy these are! 

Designed with an elasticated waist, relaxed but tapered legs, and of course our cheeky little zipper message & sulphur ankle stitching. Our Gaia is relaxed, fun and iconic… just like you! 😘

Oh, and did we mention we’ve increased the size range of our Gaias meaning even more people can join the fun? 🙌

Why you'll love it
  • Unisex relaxed fit, designed for comfort and movement
  • Made with organic cotton twill
  • Colourful Gaia jeans in 2-way stretch twill
  • Fun features like our fly zipper message and sulphur ankle seam stitching
  • Elasticated waistband for a comfortable fit
  • Relaxed thighs tapering to the ankle for a flattering shape
  • Roll-up or down flexibility for versatile styling
  • Now offered in an extended size range from 24 to 40, welcoming more adventurers
