14 Best Men’s Performance Underwear for Running & Gym 2026

Nothing derails a good workout faster than uncomfortable underwear.

You need gear that moves with you, keeps everything in place, and actually performs when you push yourself.

We’ve done the research and testing to bring you this comprehensive guide to the 14 best men’s performance underwear options for 2026. Each pair has been evaluated on crucial factors like moisture wicking ability, chafe resistance, support structure, fabric breathability, and durability during high intensity workouts. You’ll find detailed breakdowns of what makes each option unique, who they’re best suited for, and specific information about sizing, materials, and pricing. Whether you’re a serious runner logging kilometres daily, a gym regular hitting heavy lifts, or someone who simply refuses to compromise on comfort during any physical activity, this guide will help you find the perfect pair.

1. SLY Collective Bamboo Pouch Boxer Briefs

SLY Collective brings a game-changing approach to performance underwear with their bamboo pouch boxer briefs that directly address the core issues active men face. You’ll find these stand apart from traditional designs through their built-in anatomical pouch that separates and supports rather than compressing everything together. The Australian brand has engineered these specifically for men who refuse to accept chafing, overheating, or constant adjustment as normal parts of their workout routine.

What makes SLY Collective bamboo pouch boxer briefs stand out

The integrated inner pouch design creates a dedicated space that prevents skin-on-skin contact, which eliminates the primary cause of chafing during movement. Your anatomy stays properly positioned and supported without compression, allowing natural temperature regulation that both bamboo fabric and the separation design facilitate. This combination helps maintain optimal conditions that research suggests may support healthier sperm production.

Bamboo fabric delivers performance advantages beyond basic moisture wicking. The material naturally resists bacterial growth, requires significantly less water to cultivate compared to cotton, and biodegrades when its useful life ends. You also get a longer leg design that prevents the frustrating ride-up problem many performance underwear suffers from, plus an integrated pocket for essentials like keys or cards during workouts.

2. Saxx Quest Quick Dry Mesh Boxer Briefs

Saxx has built a reputation specifically around their anatomical pouch technology, and the Quest Quick Dry Mesh boxer briefs represent their most breathable execution of this concept. These boxer briefs target active men who struggle with excessive heat buildup during workouts through an engineered mesh construction that promotes constant airflow where traditional underwear typically traps heat. The brand’s signature approach separates your anatomy from your legs using an internal hammock-like structure, which directly addresses both comfort and temperature concerns.

What makes Saxx Quest quick dry mesh boxer briefs stand out

The BallPark Pouch design uses two internal mesh panels that create a suspended hammock structure, keeping everything separated from your thighs and promoting airflow from multiple angles. This construction prevents the skin-on-skin contact that causes chafing whilst simultaneously allowing heat to escape rather than accumulate. Your anatomy stays positioned naturally without compression or restriction.

Material selection reinforces the cooling approach with 77% nylon, 14% elastane, and 9% polyester creating a breathable mesh that wicks moisture rapidly. You’ll notice the fabric feels substantially more open than standard performance materials, allowing air to move through rather than just along the surface. The waistband construction particularly impresses with its ability to maintain tension without folding over during squats or bending movements.

You’ll benefit most from these if overheating during workouts consistently affects your performance or comfort.

A silicon grip strip runs along the bottom hem of each leg, actively preventing ride-up without creating uncomfortable compression. This design detail solves the constant adjustment issue many runners face after a few kilometres. The fabric blend wicks moisture efficiently whilst maintaining breathability, keeping you dry even when your pace pushes into higher intensity zones.
