Size Guide

The Roo Boxer runs true to size with an athletic taper. When in doubt, size up — our Modal blend has plenty of give.

The Roo Boxer

How to Measure

Wrap a measuring tape around your natural waistline — the narrowest part of your torso, usually just above the belly button. Keep the tape snug but not tight, and measure over a thin layer for the most accurate result.

Fit Notes

  • • Mid-rise athletic taper — cut close, not compressing.
  • • 9% Elastane gives generous 360° stretch.
  • • Between sizes? Size up for a more relaxed fit.
  • • Low-pro waistband sits flat under pants.

Not sure? We offer 30-day hassle-free returns and exchanges. Try the Roo Boxer on the course — if it doesn't move with you, send it back.

The Roo Cap

SizeHead (in)Head (cm)
S/M21 ⅝″–22 ¾″55–58 cm
L/XL22 ¾″–24″58–61 cm

How to Measure

Wrap a measuring tape around your head about ⅛″ above your ears and across the middle of your forehead, keeping it level. Measure where the cap will sit — snug but not tight.

Fit Notes

  • • Structured 6-panel classic fit.
  • • Adjustable snapback closure for a custom fit.
  • • Between sizes? Size down — the snapback has plenty of give.
  • • One size up or down from your true measurement still works.

Not sure? The adjustable snapback makes the Roo Cap forgiving — most players fit the S/M comfortably. Not the right fit? 30-day hassle-free returns apply.
