TOUGHMESH™ DETAILS

NYLON FOR ADDED TOUGHNESS
To make the fabric tough enough, we use nylon (then add a little stretch). The polyester version repeatedly failed our testing and cost us an extra year that we’ll never get back.

FEATHERWEIGHT
ToughMesh™ weighs only 100GSM (grams per square meter). That’s 30-40% less weight than normal performance fabrics. Cotton/poly tri-blend weighs in at 145 GSM and other performance shirts at 170-190 GSM — it’s a big difference.

INCREASED AIRFLOW
Mini-perforations are woven into the fabric to increase airflow, speed up dry time, and decrease weight. They’re small and mighty but do not dominate the aesthetic of the shirt.

SUN PROTECTION
ToughMesh™ offers 35 UPF. This means our shirt will provide protection from UV rays. The sun has lots of power, especially in Florida.
“It took us five years to find the fabric to build the best performance shirt I’ve ever worn. We know how to build stuff right — in this case, what eluded us was world class fabric. Past versions were tough, but weighed too much. They were comfortable, but didn’t dry fast enough. We tested tons of great fabrics over the years that are proven for other uses like cycling or running, but all had a fatal flaw: weakness. It was discouraging to fail over and over and over.”
