Padded Cycling Shorts for Men: Chamois, Padding and Fit
Padded cycling shorts for men are shorts with a sewn-in pad, usually called a chamois (say "shammy"), that sits between you and the saddle. The pad spreads pressure across your sit bones, cushions road buzz and, together with flat seams and a snug fit, cuts down on the rubbing that causes soreness. You can get them as Lycra shorts, bib shorts or padded undershorts that you wear under your normal clothes. The right one depends on how long you ride and how you want to look off the bike.
What are padded bike shorts called?
You will hear several names for the same idea. "Chamois" refers to the pad itself, a nod to the leather pads used decades ago before synthetic foams and gels took over. "Bib shorts" are padded shorts held up by shoulder straps rather than a waistband. "Padded liners", "padded undershorts" or "cycling underwear" are thinner, underwear-style garments with a pad, designed to go under baggy shorts, trousers or jeans. "Knicks" is mostly an Australian term you might see online. Whichever word you search for, you end up in the same product family: a close-fitting garment with a pad in the seat.
The main types of padded shorts for men
| Type | Best for | Pros | Watch out for |
|---|---|---|---|
| Padded cycling underwear (undershorts) | Commuting, leisure rides, spin classes, touring in normal clothes | Discreet, works under anything, usually cheaper | Must fit snugly; wear it without other underwear |
| Lycra padded shorts | Road rides, club runs, fitness riding | Close fit, easy toilet stops | The waistband can roll or dig in on long rides |
| Bib shorts | Long road rides and sportives | No waistband, the pad stays put when you lean forward | Fiddly for toilet breaks, usually more expensive |
| Baggy MTB shorts with a liner | Trail riding and casual rides | Relaxed look, pockets | Liner quality varies a lot |
If you mainly ride to work or in everyday clothes, padded undershorts give you most of the comfort without the full-kit look. If you spend hours in a low road position, bibs are worth a look. For trail riding, see our guide to MTB shorts with padding.
What type of padding is best for cycling shorts?
There is no single best pad, only the best pad for your ride length, your position and your saddle. Three things matter more than the marketing name.
Foam, gel or both
Most pads are made of foam, often in several densities: firmer where your sit bones press down, softer elsewhere. Gel pads, or foam pads with gel inserts, add a cushioning layer that many riders find helpful on rough roads and long seated stretches. Labels such as "3D", "4D" or "5D" usually describe how the pad is shaped and layered rather than a formal standard, so look at the shape and the zones rather than the number.
Thickness and shape
Thicker is not always better. A very thick pad on a soft, wide saddle can feel like sitting on a pillow and may move around, which causes rubbing. A medium pad that follows your shape and stays in place is usually the comfortable choice. Look for one that is fuller under the sit bones and thinner at the front and edges, so it does not bunch between your thighs.
Breathability
Heat and sweat are behind a lot of saddle discomfort. Perforated or channelled pads and mesh fabrics let moisture escape and dry faster, which matters on summer rides and even more indoors.
How padded shorts should fit
- Snug, not tight: the shorts should hold the pad against your body without squeezing. Loose shorts let the pad slide, and sliding is what rubs.
- Pad in the right place: sit on a chair, lean forward as you would on the bike and check that the pad covers your sit bones and the area just in front of them.
- Legs and waist stay put: the leg ends should not ride up, and the waistband should not dig in when you lean forward.
- Flat seams: seams around the pad and inner thigh should lie flat against the skin.
Sizes vary between brands, so measure your waist and hips and compare them with the size chart instead of guessing from your jeans size. Our cycling underwear size guide walks you through it step by step.
Do you wear underwear under padded cycling shorts?
No. Padded shorts are designed to be worn next to the skin. A layer of normal underwear adds seams in exactly the wrong places, traps moisture and lets the pad move. Put on a clean pair for every ride and change out of them soon after you finish.

Caring for padded shorts
- Wash them after every ride, inside out, on a cool cycle.
- Skip fabric softener, which can clog breathable fabrics.
- Let them air-dry, away from radiators and tumble dryers, which can damage the pad and the elastic.
- Rotate two or three pairs so each one dries fully between rides.
Comfort beyond the shorts
Shorts are only part of the picture. Saddle height, saddle shape and how long you have been riding all play a role. If you get sore, read our guide on how to prevent saddle sores and chafing. If numbness, pain or skin problems persist or keep coming back, see your GP or a physiotherapist.
Frequently asked questions
What are padded bike shorts called?
The pad is called a chamois. Shorts with one are called padded cycling shorts, bib shorts (when they have straps) or padded liners and undershorts (when they go under other clothes). All of them put a pad between you and the saddle.
Are padded cycling undershorts as good as Lycra shorts?
For commuting, leisure rides and spin classes, many riders find padded undershorts just as comfortable, and they are easier to wear with normal clothes. On long, fast road rides in a low position, close-fitting Lycra shorts or bibs keep the pad more stable.
Is gel or foam padding better for cycling shorts?
Neither wins every time. Multi-density foam is light and supportive, while gel adds cushioning that can help on rough surfaces and long seated stretches. Fit and pad shape matter more than the material.
How tight should men's padded cycling shorts be?
Snug enough that the pad does not move when you pedal, but not so tight that the waist or legs dig in. If you are between sizes, compare your measurements with the size chart rather than sizing down out of habit.
How often should I replace padded shorts?
Replace them when the pad goes flat, the fabric turns see-through or the elastic loses its grip. How quickly that happens depends on how often you ride and wash them.
