Why we made it

Our Bataboom organic cotton sweatpants: Insanely comfortable and wonderfully stretchy! 🤸‍♀️

Not only is our newest version Bataboom even comfier than before thanks to it's super soft organic cotton and cosy brushed interior - but we've also upgraded the stitching to a flatlock stitch for a more flush look! 😎

Be comfy and look great! Designed with tapered legs to give a flattering silhouette whilst still offering plenty of room around the thighs for movement - plus you can customise your fit with our adjustable cuffs & rollable waistband! 

Batabooms have been a consistent favourite for years, especially during those chillier months thanks to the soft brushed interior!

Of course for this season we've also made it in some beautiful new colours! 💚💜🧡🖤

Why you'll love it
  • Made with super soft organic cotton
  • New flatlock stitching for sleekness
  • Brushed interior for extra cosiness
  • Made with elastane for full range of motion
