PRINTED ON HYPRCLOTH®

95% PERUVIAN PIMA COTTON. 5% SPANDEX

HYPRCLOTH® is the result of six years of relentless refinement. Developed using ultra-soft Peruvian Pima cotton with added stretch. This material is our flagship tool used in all our graphic tees.

PERFECTED FIT

The fabric is heavyweight, enzyme washed, and pre-shrunk. Designed with a longer-than-usual fit for an extended silhouette. No warping, no fading, built-to-last.

Model is 5' 11" wearing size M

Soft Peruvian Pima Cotton

Made with 95% Peruvian Pima cotton for a smooth, soft feel against the skin. The fabric is enzyme washed for additional softness.

Heavyweight 260 GSM Fabric

We use a thicker, heavier fabric to give the shirt structure and support the weight of our large screen prints.

Four-Way Stretch

The fabric stretches lengthwise and across its width. The 5% spandex adds flexibility and helps the fabric return to its original shape after stretching.

Pre-Shrunk Fabric

We pre-shrink the fabric during production to help reduce shrinkage after washing. Following the care instructions helps maintain the fit.

HAND-PRINTED IN SD

Our team prints the shirts in our own warehouse. We handle the printing directly, including the color, detail, and finish.

HIGH DENSITY REFLECTIVE INK

Custom-developed, dense grey ink infused with glass micro-beads. When hit by direct light, the ink reflects bright white, making the graphic impossible to miss.

Before

After

Specialized UV-Reactive Ink

Custom-formulated inks that come alive under black light. Bringing the graphics to life in environments where conventional prints disappear.

REAL HOLOGRAPHIC FILM

Holographic ink shifts through a spectrum of colors as the viewing angle changes. Real film, not vinyl transfer. We melt a sheet of compressed dust particles onto water-based adhesive after the cure. Nobody else does it this way.
