FAQs

What materials are your boxers made from?

Our boxers are crafted from a premium 93% cotton, 7% spandex blend. Combining natural softness with the flexibility needed for everyday movement. The fabric is breathable, supportive, and designed to retain its shape over time, while every detail, from the waistband to the stitching, is refined for lasting comfort.

How do I find my size?

Our boxers are available in sizes S, M, L and XL.

For the most accurate fit, we recommend using your waist measurement:

  • Small (S) - 28–30” (71–76 cm)

  • Medium (M) - 32–34” (81–86 cm)

  • Large (L) - 36–38” (91–97 cm)

  • Extra Large (XL) - 40–42” (102–107 cm)

If you’re between sizes, we recommend sizing up for a more relaxed fit.

A detailed sizing guide is also available on each product page for further guidance.
