What to Wear for Indoor Cycling: Sleeveless Jerseys and Bibs for the Trainer
For indoor cycling, wear a sleeveless or short sleeve cycling jersey, padded bib shorts and short cycling socks, with nothing underneath the shorts. On a trainer there is no wind to carry heat away, so you sweat more than on the road. Put a fan in front of the bike and a towel on the bars.
In short
- A sleeveless jersey and padded bib shorts are the core of an indoor kit.
- No wind reaches you on a trainer, so a fan and a towel matter as much as the clothes.
- Skip cotton T-shirts, underwear under the chamois and anything loose.
- Wash the kit after every session, at 86°F (30°C), and let it air dry.
What should you wear for indoor cycling?
Picture the clothes you wear on the road in July, then take away anything you would only need for wind, rain or traffic. Most riders end up with three pieces: a light jersey, padded bib shorts and short socks. Shoes are the same cycling shoes you use outside, because your pedals do not change.
The jersey can be sleeveless or short sleeve. A sleeveless jersey leaves your arms and shoulders open to the fan, which is why it has become the usual trainer top. A short sleeve jersey works too, and many riders simply use the summer jerseys they already own.
Below the waist, padded cycling bibs or shorts are not optional. You sit still on the saddle for the whole session indoors, with fewer of the small shifts and out-of-the-saddle moments a road ride gives you, so the chamois does even more work than outside.
What you leave out matters as much. No vest, no jacket, no arm warmers, no reflective layer. Even a helmet is optional on a fixed trainer, though some riders keep a cap on to stop sweat running into their eyes.
Why do so many riders wear a sleeveless jersey on the trainer?
Because the fan is your only breeze. On the road, moving air takes heat off your arms and chest the whole time. Indoors that stops, and the room warms up as you ride. Bare arms let the fan reach more skin.
Our sleeveless tech jerseys are built the same way as our short sleeve jerseys. The Men's Ride Forever Infinity Sleeveless Tech Cycling Jersey uses LEMBO 140 GSM moisture-wicking polyester with 110 GSM mesh side panels, which the product page describes as cooling. It has three reinforced back pockets, a full-length hidden zip and a silicone waist gripper. The Women's Hawaiian Aloha Floral Sleeveless Tech Cycling Jersey is cut for the women's body shape, with large mesh side panels and the same fabric.
The full-length zip earns its place indoors as well. Open it halfway through a hard interval and you get air on your chest without stopping the workout.
You may wonder why you would need back pockets on a bike that goes nowhere. They are handy for a phone you want off the floor, an energy bar or the TV remote. More to the point, a sleeveless jersey you buy for the trainer also works outside next summer, pockets included.
Our full range sits in sleeveless cycling jerseys, with separate men's sleeveless jerseys and women's sleeveless jerseys. They have a club fit cut and run small, so size up if you are between sizes and check the size chart first.
Bib shorts or cycling shorts for indoor rides?
Either works, and the choice is closer indoors than outside. Bibs keep the chamois in place with shoulder straps, so nothing slides when you sweat. Waist shorts are easier to pull on and off, which some riders like for a 45-minute session before work.
Our Men's Plain Color Pro-Band Gel Padded Cycling Bib and Women's Pro-Band Classic Plain Color Gel Padded Cycling Bib both list a 9D contoured silicone gel pad, wide 45 mm silicone leg grippers and an 80% polyester, 20% Lycra fabric marked quick dry. The pad is what you will notice most on a long indoor session, since your weight stays on the saddle. Browse cycling bibs for the full range.
Wear the bibs or shorts with nothing underneath. Underwear adds seams and holds sweat right where you sit. Our guide on whether you wear underwear with cycling shorts explains why, and bib shorts vs cycling shorts goes through that choice in more detail.
How do you deal with sweat on an indoor trainer?
Start with the room. A fan pointed at your chest and face is the single most useful thing you can add, and a second one aimed at your back helps on long rides. Open a window if you can.
Then protect the bike. Sweat drips onto the top tube, the headset and the floor. A towel over the handlebars catches most of it, and a mat under the bike looks after the floor. Some riders keep a second small towel within reach for their face.
Drink more than you would outside. With no wind you may not notice how much you are losing, so set two full bottles in the cages before you start. My guess is that most riders who feel flat after 30 minutes indoors simply ran out of water, not legs.
Your kit helps in a smaller way. A moisture-wicking jersey and bibs marked quick dry will not stop the sweat, but they will not turn into a wet layer of cotton either. Short socks matter too: the Unisex Polka Dot Mid Length Cycling Socks are nylon and elastane, and the product page says nylon dries fast and keeps the sock from bunching inside cycling shoes.
What should you not wear for indoor cycling?
A cotton T-shirt is the most common mistake. Cotton holds sweat and gets heavy, so by the end of a session it is a wet towel stuck to your back. Loose gym shorts are next: the fabric bunches at the saddle and there is no pad.
| Skip this | Wear this instead | Why |
|---|---|---|
| Cotton T-shirt | Sleeveless or short sleeve cycling jersey | Cotton holds sweat |
| Gym or running shorts | Padded bib shorts or cycling shorts | You need the pad on the saddle |
| Underwear under the chamois | Nothing underneath | Seams and trapped sweat |
| Thick cotton socks | Short cycling socks | Cotton stays wet in shoes |
| Vest, jacket, arm warmers | Nothing extra | There is no wind or cold indoors |
A long sleeve thermal jersey is the other trap. It is the right call on a November morning outside, but on the trainer it only adds heat. Keep it for the road, and see our temperature guide for when it makes sense.
If you ride with a training app such as Zwift, the kit does not change. A screen in front of you just makes it easier to forget to drink.
How do you wash indoor kit after a sweaty session?
Wash it after every ride. Indoor kit gets just as wet as summer kit, and a damp chamois left in a bag is where saddle problems start. Our product pages give the same care line for jerseys and bibs: machine wash at 86°F (30°C), do not dry clean or iron.
Turn the bibs inside out, close the jersey zip and skip fabric softener. Hang everything to dry instead of using the dryer. If you ride indoors most days, two sets of bibs and jerseys let one dry while you wear the other. Our beginner kit and washing guide has the step-by-step.

Frequently asked questions
Can I wear a regular T-shirt for indoor cycling?
You can, but cotton holds sweat and gets heavy within minutes. A cycling jersey made of moisture-wicking polyester, such as our sleeveless cycling jerseys, stays lighter on a long session.
Do you need padded shorts for indoor cycling?
Yes. You stay seated more on a trainer than on the road, so a padded chamois matters even more. Wear bib shorts or cycling shorts with nothing underneath.
Is a sleeveless jersey better than a short sleeve jersey indoors?
Many riders prefer sleeveless on the trainer because the fan reaches the arms and shoulders. A short sleeve jersey works too, so use what you already own.
Do you need a helmet on an indoor trainer?
On a fixed trainer that does not move, most riders leave it off. A cycling cap can keep sweat out of your eyes.
How often should you wash indoor cycling kit?
After every session. Machine wash at 86°F (30°C), skip fabric softener and hang it to dry.
