  • Soft-touch cotton against your skin
No Stitch. No Itch.
TUBE-KNIT CONSTRUCTION

No Stitch. No Itch.

Traditional undershirts are sewn together along the sides, creating stiff seams that rub and irritate. ARAX uses tube-knit construction, the body is knitted as a single seamless tube, eliminating side seams entirely. The result is an undershirt so comfortable you forget you're wearing it.

  • Zero side seams, no friction or pressure points
  • Tag-free design for itch-free wear
  • Prevents ripping at seam lines

Frequently Asked Questions

How does the sweat-proof pad work?
The Cotton Shield is a specially treated cotton layer sewn into the underarm area. It absorbs moisture on the inside while preventing it from passing through to the outside. Unlike synthetic alternatives, it's 100% cotton against your skin.
Will the pads make the shirt feel bulky?
Not at all. Each pad is precision-tailored in two separate pieces to follow your natural arm movement. They're thin enough that the shirt looks and feels like a regular undershirt.
What sizes are available?
ARAX is available in M, L, XL, XXL, and 3XL. Check our size guide in the product section for detailed measurements.
How do I wash it?
Machine wash cold with like colors. Tumble dry on low heat. The Cotton Shield technology is built to last through hundreds of wash cycles.
What is your return policy?
We offer a 14-day satisfaction guarantee. If you're not completely satisfied, return your unworn shirt in its original packaging for a full refund.
Is it really 100% cotton?
The outer shell and the two outer layers of the sweat pad are 100% Egyptian-made premium cotton. The inner moisture-barrier layer uses a proprietary treatment to prevent sweat from passing through.
