Best Underwear for Cyclists: Prevent Saddle Sores and Chafing
Written by Bill MPublished on September 1, 2025Why Regular Underwear Is Sabotaging Your Ride
Here's the brutal truth: that cotton underwear you grabbed from your dresser this morning is basically sandpaper with a waistband. Cotton absorbs moisture like a drunk uncle absorbs beer, holding onto every drop of sweat and creating the perfect storm of friction, bacteria, and misery.
Regular underwear fails cyclists because it lacks the three essential features your nether regions desperately need:
- Moisture-wicking technology to keep you dry
- Seamless construction to eliminate friction points
- Strategic support to prevent uncomfortable shifting and bunching
When you're pedaling for hours, every seam becomes a potential hot spot, every bit of retained moisture becomes a breeding ground for bacteria, and every moment of fabric bunching becomes another step toward saddle sore hell.
The Science Behind Saddle Sores and Chafing
Saddle sores aren't just "part of cycling"—they're completely preventable with the right approach. These painful, inflamed bumps develop when three factors combine: pressure, moisture, and friction. Your sit bones bear most of your weight, while your inner thighs and perineum deal with constant rubbing against the saddle.
Moisture significantly increases friction and creates ideal conditions for saddle sore development, which explains why that "just a quick ride" in regular clothes turns into a painful reminder of poor fabric choices. The key is breaking this cycle before it starts.
Understanding Your Body's Needs
Different riding positions create different pressure points. Road cyclists in aggressive positions put more pressure on the perineum, while upright riders stress their sit bones more. Mountain bikers deal with constant position changes that can cause fabric to shift and bunch.
The anatomy matters too—everyone's built differently, and what works for your riding buddy might leave you walking like a cowboy who lost his horse.
Our Ball Hammock® Pouch Underwear: The Game-Changer
We didn't just stumble into making the world's most comfortable underwear—we engineered it specifically for guys who demand more from their gear. Our Ball Hammock® Pouch Underwear features luxury 95% MicroModal and 5% Spandex that's specifically designed to keep you comfortable mile after mile.
Here's what makes our underwear different:
- Proprietary knitting process that delivers more sumptuous Modal per square inch
- Moisture-wicking and breathable fabric with superior moisture management properties
- Supportive pouch design that keeps everything in place
- Anti-bunching, no-itch stitching with 4-way stretch
- Perfectly compressive fit that prevents ride-up
The secret sauce is our Modal fabric technology. Not all Modal is created equal—our proprietary process creates a softer, more durable, and better-fitting product than anything else on the market. Modal fabric absorbs 50% more moisture than cotton while maintaining superior moisture-wicking properties. It's like wrapping your junk in a cloud that happens to be engineered by NASA.
Essential Features to Look for in Cycling Underwear
Fabric Technology
The fabric is everything. Look for moisture-wicking synthetic blends or high-quality Modal that pulls sweat away from your skin. Avoid cotton like it's your ex—it holds moisture, creates friction, and will leave you chafed and cranky.
Antimicrobial treatments are crucial for longer rides, as heat and moisture from sweat create conditions for bacterial and fungal growth, especially during multi-day adventures. For cyclists who really struggle with overheating, our paradICE™ cooling underwear collection uses patented cooling fabric that's scientifically proven to keep you up to 3° cooler.
Construction and Fit
Seamless or flat-seam construction is non-negotiable. Every seam is a potential friction point, and when you're doing thousands of pedal strokes, even tiny imperfections become major problems.
The fit should be snug but not restrictive—think second skin, not sausage casing. Loose underwear bunches and creates hot spots, while overly tight options restrict blood flow and create pressure points.
Support and Design
A proper pouch design keeps everything secure without being restrictive. Your gear shouldn't be bouncing around or getting squished against your thighs—that's a recipe for discomfort and potential numbness.
Sizing and Fit Guide for Maximum Comfort
Getting the right fit is crucial for saddle sore prevention. Here's how to nail it:
- Waist measurement: Measure at your natural waistline, not where your pants sit
- Leg opening: Should be snug enough to prevent ride-up but not tight enough to create pressure lines
- Length consideration: Longer inseams provide more coverage but can bunch under tight cycling shorts
When in doubt, size up slightly—it's better to have a looser fit than create pressure points that lead to saddle sores. For cyclists who prefer extra coverage under their cycling shorts, our long boxer briefs offer an additional 2.5 inches of thigh coverage with the same Ball Hammock® technology.
Beyond Underwear: Complete Saddle Sore Prevention
Hygiene and Care
Clean underwear for every ride isn't just good manners—it's saddle sore prevention 101. Not washing cycling gear after each use is a cited risk factor for saddle sores.
Shower immediately after rides when possible, and if you can't, at least change out of sweaty gear. Your underwear should be washed after every ride and hung to dry properly—never stuff damp gear in a bag where bacteria can party.
Chamois Cream and Lubrication
Even the best underwear benefits from proper lubrication. Chamois cream is the most commonly cited prevention method, used as a lubricant to reduce chafing from seat friction. Apply chamois cream to your skin, not the fabric, focusing on areas prone to friction. Reapply on longer rides as needed.
Avoid petroleum-based products that can break down technical fabrics. Stick to cycling-specific creams designed to work with moisture-wicking materials.
Bike Fit and Saddle Selection
The best underwear in the world can't overcome a terrible bike fit or wrong saddle. Make sure your saddle height, angle, and position are dialed in. A professional bike fit is worth every penny if you're dealing with recurring saddle sore issues.
When to Seek Help
Most saddle sores resolve with rest in the early stages, with topical treatments recommended for small sores, but some situations require medical attention. See a healthcare provider if you experience fever, spreading redness, or sores that don't improve after a few days of rest.
Don't tough it out—serious infections can develop from untreated saddle sores, and early intervention is always easier than dealing with complications later.

Frequently Asked Questions
What causes saddle sores and how can I prevent them?
Saddle sores develop when three factors combine: pressure from your body weight on the saddle, moisture from sweat, and friction from fabric rubbing against skin. Prevention requires moisture-wicking underwear with seamless construction, proper bike fit, good hygiene practices, and using chamois cream as a lubricant to reduce friction.
Why is cotton underwear bad for cycling?
Cotton absorbs moisture like a sponge but doesn't wick it away from your skin, creating a wet environment that increases friction and promotes bacterial growth. Cotton also lacks the seamless construction and strategic support needed for cycling, making it essentially "sandpaper with a waistband" for long rides.
What fabric should I look for in cycling underwear?
Look for moisture-wicking synthetic blends or high-quality Modal fabrics that pull sweat away from your skin. Modal is particularly effective, absorbing 50% more moisture than cotton while maintaining superior wicking properties. Avoid cotton entirely, and seek fabrics with antimicrobial treatments for longer rides.
How should cycling underwear fit to prevent chafing?
Cycling underwear should fit like a second skin—snug but not restrictive. Look for seamless or flat-seam construction to eliminate friction points, and ensure the leg openings are tight enough to prevent ride-up but not so tight they create pressure lines. A proper pouch design keeps everything secure without being restrictive.
Key Insights
- Cotton underwear is your enemy: Regular cotton underwear absorbs and retains moisture, creating the perfect conditions for friction, bacterial growth, and saddle sores that can end your ride early.
- Three factors create saddle sores: Pressure, moisture, and friction combine to cause painful inflammation. Breaking this cycle requires moisture-wicking fabrics, seamless construction, and proper support.
