Responsible and sustainable, Janji makes high performance gear that lets you focus on the joy of running

Janji’s running and athletic gear packs effective tech into every square inch to make a range that’s clean, classic, and comfortable—and most importantly, ready to keep up with your regimen every step of the way. Add in their commitment to sustainable materials and responsible manufacturing and this gear feels good any way you look at it. The Runterra Bio Tee is constructed using an innovative cotton/synthetic blend to offer the moisture-wicking and anti-odor properties of synthetic fabrics with the comfort and biodegradability of cotton.


  • A do-it-all shirt built for active comfort and performance on long runs
  • Made from an ultra-light and breathable cotton/poly blend fabric that fights odors and wicks moisture while drying quickly
  • Innovative, specially-formulated polyester breaks down in a landfill environment in 4 years instead of 400
  • Modified raglan-sleeve design features rolled-back shoulder seams for chafe-free comfort
  • Fabric is OEKO-TEX® certified to be free from harmful chemicals and fabricated to meet high environmental standards
  • Janji gives 2% of proceeds from every purchase to support clean water projects
  • 70% Supima® cotton, 30% 37.5® tech polyester
  • The Runterra Bio Tee is made with natural fibers so some shrinkage may occur on the first wash
