Materials Compared: What Works Best

How to Choose the Right Pair

1. Prioritize Fit Over Style

• Opt for boxer briefs or athletic briefs with a 6–8” inseam to prevent riding up.

• Pro Tip: RMAC’s Best Fit Quiz helps you match your body type to their pouch sizes.

2. Check for Quick-Dry Tech

• Fabrics should dry within 2–4 hours after a soak.

3. Test the Waistband

• Avoid elastic that digs in. RMAC’s Modal Boxer Briefs use a soft, wide waistband that stays put without pressure.

Care Tips to Extend Lifespan

• Wash in cold water and avoid fabric softeners to preserve moisture-wicking coatings.

• Air-dry instead of using a dryer to prevent shrinkage.

• Rotate between 2–3 pairs to reduce wear during frequent trips.
