Underwear for cycle commuting

Short answer: Choose a garment that fits close, moves moisture and has no seams that rub against the saddle. If the ride is long or it rains, bring a clean pair and change when you arrive.

Seams and saddle

On the bike, the seams press against the saddle for the whole ride, and every pedal stroke shifts them slightly. A thick or hard seam in the crotch quickly becomes a sore spot. A style with a flat seam rubs the least and is barely noticeable after half an hour. See the styles in bamboo boxers.

A close fit against chafing

A loose garment folds when you lean forward and pedal, and the fold becomes a friction point. A close fitting one stays still against the skin and follows the movement instead of working against it. The same goes for the trousers on top, which should not be tight in the crotch. See the fits in men's bamboo sweatpants.

Moisture is the main problem

Even on a calm ride you sweat, and the fabric against the saddle gets no air. Damp skin becomes softer and more sensitive, and before long it starts to sting. A fabric that moves moisture away from the skin and dries quickly makes a clear difference, especially on warm days and uphill.

A clean pair at work

After half an hour of commuting in rain or heat, the fabric is damp. Sitting in it for the rest of the day is neither pleasant nor good for the skin. Keep a clean pair in your bag or a desk drawer and change when you arrive. Take one from bamboo panties or the men's styles.

The waistband under your jacket

When you lean over the handlebars, your trousers pull down at the back and the waistband carries more. A wide, soft waistband stays put without cutting in. A narrow, tight one can roll and press, and you feel it after a few kilometres. Choose a waistband that holds without pinching.

Long legs or short

Styles with slightly longer legs protect the inner thighs from chafing, because skin does not rub against skin or against the trousers. Short styles are airier and less bulky. If you ride far or often chafe on the thighs, longer legs are worth trying. On the saddle, the seams still decide comfort.

Rain and cold

In winter and in rain, the aim is to keep the skin dry. A wet layer against the body cools quickly while you wait at a red light. Wear rain trousers over your clothes and keep the underwear thin, so it dries fast afterwards. A thick fabric that has soaked up water turns cold and heavy.

Wash after every ride

Underwear worn on the bike should be washed after each use, even if it does not feel wet. Sweat and salt settle in the fabric and can cause odour and irritation. Wash at 40 degrees, turn the garment inside out and let it air dry. That way fabric and waistband keep their shape longer.

Frequently asked questions

Can you cycle in ordinary underwear

Yes, on short rides it works fine. On long rides, seams, fit and moisture matter more, and you quickly notice the difference between a good and a poor style.

Why does it chafe most in summer

Moisture softens the skin, and friction bites faster. A fabric that dries quickly and a clean pair to change into at work help most on warm days.

Do longer legs help

Yes, against chafing on the thighs, because skin does not rub against skin. On the saddle itself, the seams in the crotch decide how comfortable the ride feels.
