Wear cycling shorts directly against bare skin without underwear, with the chamois pad centered and flat against your sit bones and the fabric pulled smooth, snug, and free of bunching.
The biggest mistake new riders make is wearing underwear under cycling shorts, which adds friction and defeats the chamois pad’s moisture-wicking job. The correct fit feels like a second skin — supportive but not tight enough to pinch or leave deep leg-gripper marks. Whether you are on bib shorts or standard waistband shorts, the rules are the same: bare skin, centered pad, smooth fabric, and the right size.
Why You Skip Underwear With Cycling Shorts
Underwear trapped between your skin and the chamois pad creates rubbing points that cause chafing on long rides. Padded cycling shorts are designed to work directly against the body, with the chamois managing moisture and reducing pressure where you contact the saddle. An extra layer also holds sweat against the skin longer, which can make saddle sores more likely. The short answer: the chamois is your underwear — trust it.
The Step-by-Step Way to Put Them On
The correct sequence matters more than most riders think. Follow these steps for a clean, chafe-free fit:
- Remove underwear and start with bare, dry skin.
- Step into the shorts and pull them up until the fabric lies smooth and close to the body.
- Adjust the chamois so it sits flat and centered under your sit bones. The fit guide from Liv Cycling recommends bending each leg slightly while guiding the pad into place with your hand so it stays firmly positioned.
- For bib shorts, place the straps over your shoulders and put your jersey on over the straps — never under.
- Do a final check: no fabric bunching or twisting, leg grippers holding without biting, chamois not shifted off-center.
Bib Shorts vs. Regular Shorts: Strap Rules
Bib shorts use shoulder straps instead of a waistband. Those straps always go under the jersey so they stay in place and don’t flap. If you wear a base layer, put it on before the bib straps but over any sports bra for women — the base layer should never sit between the chamois and your skin. Regular waistband shorts skip the strap step, but the bare-skin and pad-position rules are identical.
Fit, Sizing, and Common Mistakes
The ideal feel is snug and supportive — think “second skin,” not compression gear that leaves marks. If the fabric wrinkles or the chamois shifts when you move, Pearl Izumi’s fitting guide advises sizing down. If the leg grippers dig in deep or breathing feels restricted, try a size up.
Before you buy, check the manufacturer’s size chart against your waist and hip measurements, because sizing varies significantly between brands. Our team tested a range of women’s options side-by-side, and you can see our top picks in our full review of the best women’s padded bike shorts.
Most common mistakes to avoid:
- Wearing underwear. It increases friction and defeats the chamois purpose.
- Buying too loose. Loose shorts let the pad shift, which causes rubbing and discomfort.
- Bib straps over the jersey. Straps over the jersey will slip and chafe.
- Off-center chamois. The pad must stay flat under your sit bones every time you pull the shorts on.
- Too tight. Grippers that leave deep marks or fabric that becomes sheer means the shorts are too small.
FAQs
Can I wear underwear under my cycling shorts for modesty?
Most cycling shorts are designed with opaque fabric and a built-in chamois that provides both coverage and comfort. Adding underwear creates extra seams and friction that directly increase chafing risk, especially on rides longer than an hour.
How do I wash padded cycling shorts?
Cold water on a gentle cycle with mild detergent keeps the chamois intact. Skip fabric softener, which clogs the pad’s moisture-wicking fibers, and line-dry rather than using a machine dryer, which can break down the chamois construction over time.
Do I need chamois cream with padded shorts?
Chamois cream helps reduce friction on rides over two hours or in hot, humid conditions. Apply it directly to your skin and the chamois pad, but use only cycling-specific creams — lotions and petroleum-based products can clog the pad and cause skin irritation.
