Why a proper cycling top beats a cotton t-shirt for riding comfort and practicality

Cycling jerseys can help keep you comfortable on the bike, prevent sunburn and give you a place to comfortably store the things you need to carry. But what's wrong with just riding in a cotton t-shirt anyway?

Wearing a cycling jersey isn't just about the right look. A cycling jersey can help keep you warmer in cold weather and cooler in warm weather and generally more comfortable. Because they're shaped to fit right when you're riding, jerseys help exclude drafts and keep the sun off.

Cut and shape

Cycling jerseys are cut long at the back and short at the front for on-bike comfort

Compared to a t-shirt, a cycling jersey usually has a longer back, shorter front, higher neck and sleeves shaped to fit when you're reaching for the handlebars.

There's a lot of variation in how closely a cycling jersey fits. Some are very close, especially if they're intended for racing. You don't want excess fabric flapping in the breeze if you're trying to go as fast as possible. This is usually called something like 'race cut'.

Other jerseys are looser and more flattering if you're not a racing snake. Look out for 'sport', 'city' or 'casual' designations.


One manufacturer's size L jersey will not be the same as another's, so try before you buy if at all possible. As a rule of thumb, Italian manufacturers tend to come up small, American-based manufacturers tend to be more generous.

Here comes the sun

Jersey fabrics vary in how effectively they block the sun. Some manufacturers provide an Sun Protection Factor (SPF) rating like that of sun cream to indicate how well they work. Look for high SPF ratings if you're riding in bright sunshine.

Some very light fabrics provide little or no protection against the sun as Sky rider Chris Froome discovered while training in South Africa early in 2014. If you're wearing light mesh or open-weave jerseys, wear sunscreen underneath.

Long v short sleeves

A long sleeve jersey helps keep you warm in winter

Long sleeves are for winter, short sleeves for summer. Except it's not quite that simple. Very lightweight long-sleeve jerseys are good for pale-skinned riders in summer as they provide an extra layer of sun protection.

However, you'll usually find long-sleeved jerseys are made from thicker, warmer fabric than short-sleeved, to keep you warm in cold weather.


Many jerseys use different fabrics in different areas, such as more breathable mesh under the armpits

Most jerseys are made of some sort of synthetic fabric that's designed to quickly carry sweat away from your skin so it can evaporate from the outside of the jersey.

This is where cycling jerseys really beat your cotton t-shirt. Cotton soaks up moisture and retains it next to your skin. That water cools down in the breeze and makes you feel chilly unless the weather is very hot. Even then, it can still leave you too cold when you stop riding.

By moving sweat away from your skin, then, jersey fabrics help maintain a constant temperature.

One natural material that works well in jerseys is wool, especially fine Merino wool. Wool is still warm when it's wet, but surprisingly comfortable in warm weather too. Pong-causing bacteria grows far more slowly on wool than on synthetics, so a wool jersey can be worn multiple times between washes before it gets smelly. That makes wool popular with commuting cyclists who don't want to have to wash a bunch of jerseys every week.

Synthetic jersey fabrics deal with the pong problem by coating the fibres so that bacteria can't take hold. Repeated washing gradually removes this coating, so jerseys tend to get smellier more quickly as they get older.

The classic trio of rear pockets

Standard cycling jerseys have open-topped three pockets at the back for your wallet, keys, snacks and so on. You might think things could fall out of them, but in practice they're deep enough this isn't a problem, and there's usually a band of elasticated fabric across the top which also helps.

An extra pocket for valuables

Many manufacturers have introduced variants on the traditional trio of pockets. It's common to find a small zipped pocket for keys and change, or a pocket with a waterproof lining for your phone. The three may also be different widths, with a narrower pocket to stash a minipump.

Women's jerseys sometimes have just two main pockets


Cycling jerseys almost universally have zips. Short zips look tidy, but you might want more ventilation if you're going to ride in warm weather.

A hidden zip

More commonly, the zip will extend to about the middle of the jersey front or right to the bottom so you can open it for ventilation when it's warm.

A zip garage stops the top of the zip irritating your neck


At the top of the zip, look out for a small flap of fabric that will cover the zip pull when it's done up. Amusingly called a 'zip garage' this stops the zip irritating your neck or getting caught in your beard.

Retro jerseys sometimes have buttons and collars, evoking the style of 1950s cycling

Acknowledged by the Telegraph as a leading cycling journalist, John Stevenson has been writing about bikes and cycling for over 30 years since discovering that people were mug enough to pay him for it rather than expecting him to do an honest day's work.

He was heavily involved in the mountain bike boom of the late 1980s as a racer, team manager and race promoter, and that led to writing for Mountain Biking UK magazine shortly after its inception. He got the gig by phoning up the editor and telling him the magazine was rubbish and he could do better. Rather than telling him to get lost, MBUK editor Tym Manley called John’s bluff and the rest is history.

Since then he has worked on MTB Pro magazine and was editor of Maximum Mountain Bike and Australian Mountain Bike magazines, before switching to the web in 2000 to work for CyclingNews.com. Along with road.cc editor Tony Farelly, John was on the launch team for BikeRadar.com and subsequently became editor in chief of Future Publishing’s group of cycling magazines and websites, including Cycling Plus, MBUK, What Mountain Bike and Procycling.

John has also written for Cyclist magazine, edited the BikeMagic website and was founding editor of TotalWomensCycling.com before handing over to someone far more representative of the site's main audience.

He joined road.cc in 2013 and these days he lives in Cambridge where the lack of hills is more than made up for by the headwinds.

All good advice here. Nothing much to add.- but when will someone produce a Bamboo jersey  - my fave material for my Tees must surely be preferable to synthetic offerings...

You do get bamboo jerseys, click here.

The Chapeau cafe jersey is bamboo as well.

Bamboo? Look up 'viscose rayon'. It's about the most environmentally unpleasant fibre there is.

I have a couple of tech tops  ( 4) that I got from uniqlo .  They are amazing .  I have and have tried many different shirts I have a couple castelli shirts that I paid a fortune for ,it’s just a fucking shirt . 

I have Nike compression tops etc etc but these uniqlo tops are easily the best . In the hot weather they really keep you cool even though they are dark colours, they work just great in the cold has well  as a base layer .they cost about £12 .   

In the spring summer  warm weather ,I just wear the tech shirt mtb shorts my small bum bag that keeps my tiny mini pump a continental supersonic spare tube 50 grams ( they fold up into virtually nothing ) a small multi tool a couple of loose  hex keys  spare chain link  a tiny pack of adeshive patches  and some rubber gloves (so if I have to do a repair I keep my hands clean ) and keys and card and phone . Sorted minimal fuss been all over the world   ( well not all over the world  I mean I have not rode the South Pacific Ocean although I did once go through a stream well a puddle in Tottenham) with that set up . Usually if you get a puncture with supersonics it’s easy to find as it disperses the chalk or what ever they use into a little circle, mini explosion , stick a patch on sorted . I can’t actually remember the last time I had a puncture. ( probably get one now on my next ride ) 

shoes are bonts no boa dial just Velcro and a ratchet  model . Boa dials are for fashion victims . 

I like  having stuff .
