The best underwear for cycling is a smooth, stretchy pair with flat seams, a leg that stays put and a fabric that moves moisture away from the skin. Long rides expose every weak spot in your underwear, so a few small details decide whether you finish comfortable or counting the minutes.
What makes a ride hard on underwear
On a bike you sit in one position for a long time while your legs keep moving. That combination creates repeated friction at the leg openings and waistband, and any bunched fabric becomes a pressure point. Warm, sweaty conditions make it worse.
- Friction: thick seams and loose fabric rub with every pedal stroke.
- Moisture: damp fabric that clings feels heavier and warmer over time.
- Movement: a leg opening that rides up or a waistband that rolls is distracting at speed.
Cuts that work on long rides
Long-leg compression shorts
A longer leg means no fabric edge sitting right where your thighs move. Our compression shorts are listed as 90% polyester and 10% spandex, a quick-drying, stretchy blend that stays close to the body without a lot of bulk.
Short-leg mesh boxer briefs
For a hot day or a shorter ride, open mesh is hard to beat for airflow. The Mesh Boxer Briefs are all-over mesh with a roomy pouch and an elastic waistband, and they come in 12 colours from S to XXL.
Lightweight trunks
If you prefer a trunk, choose something light that dries fast. The Ice Silk Trunks use soft modal fabric with flat seams and mesh panels for airflow, in a low-rise cut that is easy to wear under shorts.
Fabric: what to look for
Pick fabrics that are stretchy, light and quick to dry. Synthetic blends and modal both fit the bill, while heavy cotton holds moisture and tends to feel damp once you sweat. For a longer breakdown of fabrics, see our mesh vs cotton vs modal guide.
Quick comparison
| Style | Best for | Why it works |
|---|---|---|
| Compression shorts | Long rides, cooler days | Long leg, fabric stays flat |
| Mesh boxer briefs | Hot weather, short rides | Maximum airflow |
| Ice silk trunks | Commutes, mixed use | Light, smooth, quick drying |
| Athletic jockstrap | Active riders who like open leg cuts | Minimal fabric, wide waistband |
Fit tips before you ride
- Choose your size by waist measurement and check our size guide if you are between sizes.
- Try new pairs on a short ride first, not on a big day.
- Put on dry underwear straight after you finish, and wash after every ride.
- Rotate two or three pairs so each one keeps its stretch.
If you wear an athletic supporter on the bike, the Athletic Jockstrap has a wide elastic waistband and a breathable knit pouch.

Frequently asked questions
What underwear is best for cycling?
A smooth, stretchy, quick-drying pair with flat seams, such as long-leg compression shorts or mesh boxer briefs, is a good starting point.
Should I wear underwear under cycling shorts?
It depends on the shorts. Some have built-in padding and are designed to be worn alone, so check the label. For regular shorts, a light pair underneath is a good idea.
Is cotton a good choice for long rides?
Cotton is fine for short, easy rides, but it dries slowly. On long or hot rides, a quick-drying blend is usually more comfortable.
How many pairs do I need?
Two or three pairs in rotation is enough for regular riders, so a pair is always clean and dry.
