Best Men’s Underpants for Rugby in 2025

Posted by Paul Souliac on April 12, 2025

Rugby isn’t just a game—it’s a test of endurance, strength, and grit. And while your jersey and boots get all the glory, your underpants are the unsung heroes. The right pair can mean the difference between dominating the scrum and struggling with chafing, sweat, or discomfort. Let’s break down what makes rugby underpants stand out in 2025 and how to choose the best for your game.

When it comes to 2025’s innovations in rugby gear, advanced moisture-wicking fabrics and targeted compression zones dominate the conversation. Brands now prioritize breathable mesh panels for heat regulation, anti-microbial treatments to combat odor during intense matches, and seamless construction to eliminate friction points.

For players seeking the top-performing rugby underwear, the best men's rugby underwear collection offers options with strategic padding for scrums and four-way stretch for lateral agility. Those needing guidance can explore our comprehensive guide to rugby undergarments, which breaks down position-specific needs—from loose forwards requiring maximum mobility to props needing reinforced durability.

Why Rugby Demands Specialized Underpants

Rugby players face unique challenges: intense physical contact, rapid directional changes, and 80 minutes of non-stop action. Ordinary underwear won’t cut it. Here’s what you need:

Anti-chafe engineering: Seamless designs prevent skin irritation during tackles or sprints.
Moisture-wicking fabrics: Stay dry even when the game goes into overtime.
Secure support: A reinforced pouch keeps everything in place during scrums or lineouts.
Durability: Survive repeated washes and rough play without losing shape.

Key Features to Look For

1. Material Matters

The fabric decides comfort. Look for:

Nylon blends: Lightweight, quick-drying, and tough enough for rugby’s demands.
Modal: Silky-soft for reduced friction, with stretch that moves with you.
Merino wool: Naturally odor-resistant for post-game freshness.

Avoid cotton—it traps moisture, leading to chafing and rashes.

2. Fit Is Everything

A loose waistband or shifting fabric can ruin your focus. Prioritize:

Adjustable waistbands: Stay snug without digging into your hips.
Leg grippers: Prevent ride-up during sidesteps or sprints.
Pouch sizing: Not all bodies are the same. Customizable support (like RMAC’s A-D sizing) ensures a secure fit.

3. Breathability + Moisture Control

Rugby generates heat. The best underpants use mesh panels or laser-cut vents in high-sweat zones (think groin and inner thighs).
