When it comes to workout gear, most men focus on shoes, shorts, or moisture-wicking tops. But there’s one piece of apparel that’s often overlooked — your underwear. Wearing the wrong pair can lead to chafing, overheating, or lack of support during exercise, ultimately affecting your performance and comfort. That’s why choosing the right boxer briefs for workouts is just as essential as choosing the right gym shoes.
Physical activity increases body temperature and sweat production, especially in the groin and upper thigh area. Wearing cotton or ill-fitting underwear during high-intensity training can lead to:
Chafing and skin irritation
Excessive sweating and odor buildup
Lack of support for your anatomy, which can be both uncomfortable and harmful long-term
According to Dr. Michael Reitano, a physician specializing in men’s health, “Tight, non-breathable underwear can increase temperature in the testicular area, potentially affecting sperm production and comfort” . This makes breathability, moisture-wicking fabric, and proper fit crucial for athletic underwear.
Here’s what separates the best workout underwear from your everyday pairs:
Look for boxer briefs with an ergonomic pouch or compression-style fit. These prevent excessive movement and reduce the risk of discomfort or strain.
Stay away from 100% cotton. Instead, opt for materials like:
Modal – ultra-soft, breathable, and sweat-resistant
Polyester blends – durable, lightweight, and fast-drying
Nylon and spandex – excellent stretch and shape retention
Mesh panels or moisture-releasing fabric zones can dramatically reduce heat buildup during intense workouts.
Choose boxer briefs with anti-roll leg bands or longer inseams (5–6 inches) to prevent bunching or riding up.
Look for flatlock seams and tagless construction to reduce friction and irritation.
These are a staple in many athletes’ wardrobes. With a smooth, performance waistband and sweat-wicking HeatGear® fabric, they keep you dry and supported without bunching up.
SAXX is known for its patented BallPark Pouch™ — a hammock-shaped pouch designed to reduce friction and movement. The Kinetic HD line is ideal for high-intensity activities and long workouts.
Lululemon brings its premium activewear engineering to underwear. This boxer brief uses modal fabric and flat seams, offering a breathable, chafe-free fit that moves with your body.
These boxer briefs feature Nike’s signature Dri-FIT tech and ergonomic seams. They’re stretchy, supportive, and ideal for high-sweat sessions like HIIT or weightlifting.
While these big-name brands are dominating the shelves, newer performance-focused brands like GAGLI are emerging with a sharper focus on athletic fit, eco-conscious materials, and elevated comfort.
GAGLI’s boxer briefs combine modal-based fabric with adaptive stretch to contour your body during motion — making them a smart alternative to legacy brands. Their subtle branding and minimalistic design appeal to modern men who want both style and performance from their base layers.
Choosing the right pair of underwear for workouts isn’t just a matter of comfort — it’s a performance and hygiene essential. Prioritize fit, fabric, breathability, and design, and your body will thank you during your next gym session.
