What Are Cycling Shorts? | Saddle Comfort, Explained

If you’ve ever finished a ride feeling sore in the saddle, cycling shorts are the piece of kit that fixes it. Designed specifically for the bent-over posture of a rider, these close-fitting shorts cut down on friction and add a layer of padding where you need it most. They’re a staple for anyone spending real time on a bike, whether that’s a weekend spin or a daily commute.

Here’s what makes them different from regular athletic wear, how to wear them properly, and how to keep them in good shape.

What Makes Cycling Shorts Different?

Cycling shorts are built for one job: keeping you comfortable while you’re on the bike. The key differences from ordinary shorts are the fit, the fabric, and the padding.

• Close, aerodynamic fit. The stretchy synthetic material hugs the body so it doesn’t flap in the wind or bunch up under a pair of bike shorts on top.
• Built-in padding, or chamois. This is the most important part. The padding adds a layer of cushioning between you and the saddle, which reduces pressure and chafing on longer rides. It is not designed as a general-purpose cushion for everyday wear, but specifically for the cycling position.
• Bib straps (optional). The strap-equipped version is called bib shorts. The straps hold the shorts up better and keep the waist area free of a tight elastic band, which can dig in when you’re leaning forward.

While the term “cycling shorts” can be used broadly for any of these, “bib shorts” always refers to the version with shoulder straps.

Do I Need To Wear Underwear?

No. Cycling shorts are designed to be worn without anything underneath.

The chamois pad works best when it sits directly against your skin. Wearing underwear adds an extra layer that can bunch up, trap moisture, and create friction, which defeats the whole purpose of the pad. The construction of the shorts, including the shape of the pad, is intended for direct contact. The entire system is meant to move with your body, not against another layer of fabric.

For the same reason, you shouldn’t use these shorts as a substitute for ordinary shorts. The padding is shaped for the cycling position, so it won’t provide the same comfort when you’re sitting upright in a chair.

How Should I Wash And Care For Them?

Proper care keeps the fabric stretchy and the padding effective, which means a few specific rules worth following.

Wash your cycling shorts immediately after each ride, and hand-washing is the best option if you have the time. If you use a machine, turn the shorts inside out, use a very low temperature (a maximum of 30°C or 86°F is advised), and never use fabric softener — it can break down the stretch fibers and ruin the fit. The same goes for high heat: skip the tumble dryer and let them air-dry. Leaving them damp in a bag is also a bad idea, as it can encourage bacteria and damage the fabric.

Beyond the washing routine, fit matters. Cycling shorts need to match your body shape and riding posture. A pair that’s too loose will rub, and one that’s too tight will restrict movement, so it’s worth trying a few sizes to see what sits correctly.

Which Type Should You Choose?

Your choice mostly comes down to how long and how far you ride. For short trips around town, a basic pair with a lighter pad is often enough. For longer rides, you’ll likely appreciate the stability of bib shorts and a more substantial chamois.
