FAQ for Boxers sizing

Fit, stretch, and which size to choose when you’re between sizes.

Should I size up or down for boxers?

Most people choose their usual size for a comfortable fit.

  • For a snug, supportive fit: choose the smaller size if you’re between sizes.
  • For a more relaxed feel: choose the larger size.
How do I measure correctly?

Measure around your waist where you normally wear your boxers. If you’re in between, use fit preference to decide.

Will they loosen up with wear?

Merino has natural elasticity. They may relax slightly with wear and then return after washing.

Do they shrink after washing?

They can settle slightly. Follow the care instructions (wool/delicate program, air dry) to keep the fit consistent.
