Most clothes are made from plastic. Ours aren’t.

Our shirts are made from bamboo fabric that’s soft, stretchy, and safe. Any strong cleaners used in making the fabric are fully washed out, and OEKO-TEX® testing makes sure the final material has no harmful chemicals.

Our underwear is made from organic cotton, so it feels clean, natural, and comfortable all day.

Our products are made in small batches to better ensure quality and uphold our non-toxic standards.

Simple. Safe. Non-toxic

Most shirts today are made with performance in mind, not health. Polyester fabrics and synthetic treatments are designed to stretch, wick, and dry fast, increasing everyday exposure of your skin, the body’s largest organ, to harsh chemical finishes

We took a different approach. Our Bamboo Athletic Tees are made to feel good and perform without the chemicals and plastics.

They’re crafted from 95% regenerative bamboo viscose with a small amount of stretch for comfort and durability, giving you an incredibly soft, lightweight feel without relying on polyester fabrics.

The fabric is dyed using OEKO-TEX® certified dyes, helping ensure the finished shirt is free from harsh chemical residues. The result is a breathable, easy wearing shirt you can move in. Great for workouts, running errands, and everything in between.

Just an everyday shirt designed with your health in mind.


  • Machine wash cold, inside out
  • For best results, hang dry
  • If needed, tumble dry on low

I really appreciate that Mellow Mile takes the time to use clean materials and small-batch production. You can feel the quality compared to fast fashion. Feels good knowing I’m supporting a brand that cares.

Bought a shirt and underwear set for my husband and he’s obsessed. He’s picky about fabrics but keeps saying how breathable and comfortable these are. Definitely coming back for more!

The fit is incredible—not too tight, not too loose. It moves with you and doesn’t lose shape. Finally found a brand that understands performance and comfort can actually go together.

Took my Mellow Mile gear on a weekend hike and it was perfect. Comfortable on the trail, still looked sharp when we grabbed dinner after. Exactly what I needed.
