What’s the best fabric for cycling in hot weather?
Because performance starts with comfort, and comfort starts with the right fabric.
Heat and humidity push your gear to the limit. The right fabric helps regulate body temperature, wick sweat, and reduce chafing. This guide breaks down the best materials for summer cycling, and why they matter.
Why fabric choice matters
Every detail counts in hot conditions, and your kit’s fabric is doing more work than you think. Here's what matters most:
- Breathability – The best fabrics release excess heat, helping you stay cool.
- Moisture control – Effective moisture management prevents discomfort and irritation.
- UV defence – Some textiles offer built-in UV resistance, reducing exposure risk.
- Weight & fit – Lightweight, close-fitting fabrics cut down bulk and improve feel.
Let’s take a look at the best fabrics for the job.
Top fabrics for hot-weather cycling
| Fabric | Pros | Cons | Our insight |
|---|---|---|---|
| Polyester (High-performance weaves) |
|
|
Look for micro-perforated or open-weave polyester for maximum airflow |
| Merino Wool (Ultralight blends) |
|
|
Best in blends. Polyester-merino mixes improve drying time while keeping the comfort and odour control |
| Nylon (Used in technical blends) |
|
|
Great for panels where durability and fit matter. Best when paired with lighter fabrics elsewhere. |
| Elastane (Spandex/Lycra) |
|
|
Use is minimal but important. Ideal for achieving a race fit without restricting movement. |
What to look for in hot-weather cycling gear
Here’s a quick checklist to help you choose the right summer cycling fabric:
- Breathability – Mesh panels and open-knit structures allow air to flow and heat to escape.
- Moisture-wicking – Essential for keeping sweat off your skin and reducing chafing.
- UV protection – Fabrics with UPF ratings (30+) offer added defence against sun exposure.
- Lightweight – The lighter the fabric, the better it handles heat and humidity.
- Quick-drying – Helps you stay dry and comfortable, even on longer rides.
Tips for riding in hot weather
If you've already sorted your kit, here's a few extra tactics can help you stay cool on hot rides:
- Hydrate properly – It sounds basic, but it’s often overlooked.
- Pre-cool your kit – A few minutes in the fridge can take the edge off the heat.
- Time your rides – Early morning or evening helps you avoid peak sun exposure.
- Use a base layer – A lightweight mesh layer can aid cooling, not hinder it.
- Apply sunblock – Especially on areas not covered by UPF-rated clothing.

FAQs
Should I wear a base layer in summer?
Yes! A lightweight mesh base layer can improve moisture transfer by pulling sweat away from your skin and helping your outer layer dry faster. It sounds counterintuitive, but it works.
Is merino wool too warm for summer?
Not when it’s ultralight or blended with synthetics. Merino helps regulate temperature and excels in humid conditions thanks to its natural breathability and odour resistance.
How do I wash performance jerseys?
Cold water, gentle cycle, and air dry. Don't use fabric softener as it clogs the fibres. Always check the care label.
Do I need UV protection in cycling gear?
Yes. Long hours in the sun add up. Look for fabrics with a UPF rating of 30+ for built-in protection, especially if you’re not wearing sunscreen underneath.
Should I avoid black kit in the heat?
Not necessarily. While darker colours absorb more heat, modern performance fabrics are designed to breathe regardless of colour. Fit and ventilation matter more.
Is it better to go sleeveless in summer?
Not always. Sleeveless kits expose more skin to UV rays and can increase sunburn risk. Lightweight short sleeves often strike a better balance between cooling and protection.
What’s the ideal fit for hot-weather kit?
Snug but not restrictive. A close fit helps wick moisture more effectively, but you still want enough airflow to prevent overheating.
