behind the design



Poly with volcanic ash

Supima cotton


This is not your typical shirt. Runterra is a blend of US-grown, long-staple Supima® cotton — which is stronger and softer than typical cotton — with a special polyester that has been blasted with volcanic particles to enhance odor-resistance, speed up dry time and provide greater thermoregulation. Yes, it has volcanic particles in it and no, you will not feel them. The fabric is incredibly soft, comfortable and durable yet lightweight, and is intended to be worn repeatedly between washes to reduce water use.

care instructions

Wash cold with like colors

Machine dry low or hang dry for best results and lifespan of the garment

Heads up — Runterra is not pre-shrunk

We have relaxed the body and slightly lengthened the sleeves of this top to accommodate for some shrinkage which may occur in the wash cycle since Runterra is made from a majority natural fiber.

Avoid washing and drying with high heat.



A lightweight yet resilient fabric that wears like soft cotton with the added performance of active odor-resistance and thermoregulation — thanks to embedded microscopic volcanic particles.

Shop All runterra


Runterra is made from premium, long-staple Supima® cotton which is 50% longer and up to 45% stronger than other cottons (and softer too). The stronger the fiber, the more durable the garment, and therefore the more it can be worn. Supima® cotton is grown by a select few family farms that utilize advanced water and soil management techniques to reduce consumption and ensure the health of the land.

Runterra fabric is also OEKO-TEX® certified meaning it is free from harmful chemicals and is fabricated in a way that meets a high environmental standard.
