How to Choose Gym Underwear: What to Look For

Quick Answer

For the gym, choose underwear made from moisture-wicking, breathable fabrics with a supportive pouch and a secure fit that prevents chafing and ride-up. Look for features like flat seams and no-roll waistbands. SAXX offers several options with these features, such as the Daytripper Comfort Stretch and Vibe Xtra Soft Comfort.

When you hit the gym, your underwear is the last thing you want to think about. But the wrong pair can cause chafing, discomfort, and distraction. Choosing the right gym underwear is about more than just fabric – it's about support, moisture management, and fit that moves with you.

Whether you're lifting weights, running, or doing yoga, your underwear needs to perform. In this guide, we'll break down the key features to look for and how to match them to your workout style.

Key Features to Look For in Athletic Underwear

Moisture-wicking fabric is non-negotiable for the gym. It pulls sweat away from your skin, keeping you dry and reducing the risk of chafing. Look for materials like polyester, nylon, or specialized blends that dry quickly. SAXX uses DropTemp® Cooling technology in some styles, which actively helps manage heat and moisture.

Support is another critical factor. A supportive pouch or contour keeps everything in place during dynamic movements. SAXX's BallPark Pouch® is designed to provide support without being restrictive. Also, consider the leg length: boxer briefs with longer legs offer more coverage and prevent ride-up, while briefs give more freedom of movement.

• Check for flat seams to minimize friction.
• Choose a waistband that stays put without digging in.

Matching Underwear to Your Workout Type

Different workouts demand different features. For high-intensity interval training (HIIT) or running, prioritize maximum breathability and moisture-wicking. A lightweight, cooling pair like the SAXX FREE DropTemp® All Day Cooling can help you stay comfortable when your body temperature spikes.

For weightlifting or CrossFit, you need durable fabric that can handle stretching and squatting without losing shape. Look for a pair with good stretch and recovery, like the Daytripper Comfort Stretch, which is built for all-day wear and movement. Yoga or Pilates might call for a softer, more flexible fabric that moves with you.

• For cardio, choose a lighter fabric with cooling properties.
• For strength training, opt for durable, stretchy materials.

Fit and Comfort Considerations

Fit is personal, but there are universal rules. The waistband should sit comfortably without rolling or pinching. The legs should not ride up during squats or lunges. If you experience chafing, consider a longer leg style or a different fabric blend.

Also, think about the rise – the distance from the crotch to the waistband. A medium rise is versatile, but some prefer a higher rise for more coverage. Try different styles to see what feels best for your body and workout routine.

• Your underwear should feel like a second skin – not too tight, not too loose.
• If you're between sizes, consider sizing up for a more relaxed fit during workouts.

Decision Rules for Gym Underwear

• If you sweat a lot: Prioritize moisture-wicking and cooling features. Look for fabrics that dry quickly and have ventilation panels. Choose a pair with cooling technology, like the SAXX FREE DropTemp® All Day Cooling.
• If you do a mix of activities: Opt for a versatile pair that balances support, stretch, and moisture management. The Daytripper Comfort Stretch is a great all-rounder for gym and daily wear.
• If you hate ride-up: Go for boxer briefs with longer legs and anti-ride-up features. Look for No-RideUp LegTM technology, as in the Daytripper.
