What to Look For?
Comfort and Fit
When you choose underwear for working out, comfort and fit should be your top priorities. You want underwear that feels good against your skin and moves with you. A snug fit gives you superior support without squeezing or causing irritation.
If your underwear is too tight, you might experience chafing or restricted movement. Too loose, and it can bunch up or shift during exercise. Styles like boxer briefs, seamless hipsters, or thongs can help you find the right balance for your body and workout style.
Accurate sizing means you get outstanding comfort and a full range of motion, which boosts your athletic performance.
Tip: Try different styles until you find the one that lets you focus on your workout, not your underwear.
Breathability and Moisture-Wicking
Breathable fabric is essential for workout underwear. You want materials that wick away sweat and keep you dry, especially during intense sessions. Synthetic blends like spandex, nylon, and microfiber offer excellent breathability and moisture management.
These fabrics pull moisture away from your skin and dry quickly, so you avoid that sticky feeling. If you sweat a lot, look for the best breathable options with mesh panels or moisture-wicking finishes. This helps prevent skin irritation and keeps you fresh, even after a tough workout.
Feature | Best Breathable Underwear for Working Out | Regular Underwear |
|---|---|---|
Moisture Control | Sweat-wicking, quick-drying | Retains moisture |
Odor Control | Best odor control, anti-chafing | Limited |
Comfort | Outstanding comfort, full range of motion | Varied |
Health and Hygiene
Health matters when picking underwear for working out. Non-breathable or ill-fitting underwear can trap sweat, leading to fungal infections, UTIs, or skin irritation. For men, tight underwear may affect reproductive health.
You should wash your workout underwear after every session to maintain hygiene. Seamless and anti-chafing designs help reduce friction and keep sensitive areas safe. Choose what feels best for you and supports your confidence.
Best Materials for Workout Underwear
The best materials for workout underwear depend on your needs. Cotton is great for sensitive skin and light activity, thanks to its softness and hypoallergenic properties. For heavy sweating or high-intensity workouts, spandex, nylon, and microfiber are top picks.
These materials offer the best odor control, stretch, and durability. Modal and Tencel blends add softness and reduce chafing. Always look for underwear for working out that matches your activity level and skin sensitivity.

Workout Underwear Care
Washing and Maintenance
Taking care of your workout underwear helps you get the most out of every pair. You want your underwear to last, stay fresh, and keep its shape. Here’s how you can do that:
Wash after every workout. Sweat and bacteria build up fast. Toss your underwear in the wash right after you exercise.
Use cold water and a gentle cycle. Hot water can break down stretchy fabrics like spandex or microfiber. Cold water keeps the fibers strong and colors bright.
Skip the fabric softener. It can coat the fabric and block its moisture-wicking abilities. Your underwear needs to breathe!
Air dry when possible. High heat from dryers can damage elastic and shrink your underwear. Hang them up or lay them flat to dry.
Turn the underwear inside out before washing. This protects the outer fabric and helps remove sweat and oils from the inside.
Tip: Friendtex underwear stands up to frequent washing. The durable seams and premium fabrics keep their shape and softness, even after many cycles.
When to Replace Your Underwear?

Loss of stretch | Waistband feels loose or saggy |
Fading or thinning fabric | Underwear looks worn or see-through |
