Cycling Jersey Side Panels: Better Than Mesh for 2026

Have you ever got back from a long cycling trip on a summer day? You remove your jersey only to realize that your sides are marked with a strange striped pattern due to falling sunlight. As a rider who spends hours in the sun, I have encountered this "checkerboard burn" one too many times. The culprit is the open mesh fabric used in most cycling jersey side panels. For quite some time, we had no choice but to accept this: good ventilation in an undesirable state of sun exposure. But in 2026, this is not the case anymore. It's time to look at a modern option that gives you great breathability and complete UV protection.

Highlights

• Cycling jerseys with old mesh side panels are often not enough to protect against the sun. This can lead to sunburn and even skin damage.
• A modern fabric option, called D036, provides both high breathability and UPF 50+ sun protection simultaneously.
• This new standard works by pulling sweat away for cooling. It doesn't leave skin exposed through big holes.
• When buying a new jersey, look for a UPF 50+ rating and choose a thick-woven side panel fabric instead of transparent mesh.

The Mesh Side Panels Are Actually Risky

For ages, mesh was regarded as the primary material for air flow. It created a direct line between the air and the skin which is the best feeling during a hot day. This is precisely why the side panels of cycling jerseys are predominantly made of this fabric.

The problem, however, is not immediate. The same holes that let air through also let harmful UV-A and UV-B rays come along. Most standard mesh has a very low sun protection rating, meaning your skin is in direct contact with them. Over time, this can lead to significant damage from the sun whether the weather is sunny or not.

Some could argue to wear sunscreen. But it is temporary. It wears off within moments due to the sweat on your skin. This leaves you vulnerable. The fabric is of course your main line of defense.

Maximum airflow has long come at the cost of minimum sun protection.

The Choice of Today: Sun Protection & Breathability

The great part is that now we have the technology. The latest development is a novel kind of functional material. For reference, we will use the term D036. These fabrics are not made of mesh. They are a terrific solution as they are tightly woven, lightweight materials.

So how do they keep you cool while also blocking the sun? It works in two smart ways.

To begin with, the tight weave physically blocks harmful sun rays from your skin. It is due to this weave that it is rated UPF 50+, the highest sun protection fabric permitted. Secondly, the secret of breathability lies in how it handles sweat. The fabric pulls sweat away from your skin and distributes it across the fabric's surface. As the moisture evaporates, it creates a strong cooling effect. Some of these fabrics also have tiny, pre-fabricated holes made by a laser cutting technique. These let vapor out without letting UV rays in. The leading companies are at the forefront of these advanced fabric technologies and are determined to strike this equilibrium.

The Showdown: Mesh & Modern Fabric

A simple comparison of the features sheds light on the dissimilarity. When the features are examined one by one, it becomes utterly clear why the new fabrics are simply the better alternative for cycling jersey side panels.

How to Spot a Sun-Proof Jersey

Are you ready for the upgrade? Here's a straightforward four-step process to find a jersey with high-performance, sun-safe cycling jersey side panels.

• Search the UPF Rating. This step is paramount. The product tag or online description should clearly specify "UPF 50+". If the rating is not mentioned, presume that it is low.
• Observe the side panels. Hold the jersey against a light source. If you can easily look through the side panel like a net, it is an old-style mesh. On the contrary, a modern panel will look solid but feel very light and thin.
• Scrutinize the product details. Look for keywords that indicate advanced fabric. Expressions like "micro-perforated," "densely woven," "coldblack®," or "UPF 50+ treated" should be present.
• Get the quality brands. Quality is promoted by leading cycling clothing companies using these materials. They are the ones creating true technical garments as they know what serious riders need for long hours of performance.

FAQ: Your Questions Answered

Q1: Is a darker colored jersey better for sun protection?

A: Generally, yes. Darker colors absorb more UV rays than lighter ones. However, a fabric's UPF rating is much more important than its color. A light-colored UPF 50+ fabric will always protect you better than a dark, open-weave mesh.

Q2: If I wear sunscreen, do I still need to worry about my mesh side panels?

A: Yes, absolutely. Sunscreen loses power when you sweat. On a hot ride, you will likely sweat off any protection under your cycling jersey side panels in less than an hour. This leaves your skin exposed. Fabric-based protection is a more reliable solution. The video below offers great tips on daily SPF use. But fabric is your best bet during hard exercise.

Q3: Are these new technical fabrics less breathable than mesh?

A: No, they just breathe in a different, more active way. Instead of just letting wind pass through, they pull sweat off your skin to cool you down through drying. During a hard effort when you are sweating a lot, this method often feels more comfortable and works better.

Q4: Will a jersey with these advanced side panels be much more expensive?

A: They are often found in premium jerseys, which can cost more. But as this technology becomes the new standard in 2026, it is appearing in more affordable options. Think of it as a smart investment in your skin health and on-bike comfort.

Q5: Can I find this technology in both men's and women's jerseys?

A: Definitely. Top cycling brands offer jerseys with advanced, sun-protective side panels for both men and women. High performance and skin protection are needs that all cyclists share.

The New Benchmark in Performance and Safety

The debate is over. The times when you had to choose between being cool and protecting your skin are gone. Traditional mesh is an old-fashioned choice that serious riders in 2026 no longer need to accept.

Dare to challenge the old way. Mesh burns the skin with UV rays. Advanced technical fabrics, the D036 standard, fuse the best of both. They offer elite cooling through high moisture management and certified UPF 50+ sun safety.

Before the next adventurous ride, check that the side panels of your jersey are safe. It's time to demand more from your gear and upgrade to the new standard of protection and performance.
