Polyester vs Cotton Tennis Shirts: What Actually Performs Better?

Polyester outperforms cotton for tennis in almost every way that matters on court: it wicks sweat instead of absorbing it, dries in minutes instead of hours, and holds its shape through long matches and hundreds of washes. Cotton feels soft in the shop, but once you're two sets deep it becomes heavy, clingy, and abrasive. That's why virtually every serious tennis shirt — including every Vexo tee — is built on a polyester base.

Why do most tennis shirts use polyester instead of cotton?

The difference comes down to how each fibre handles water. Cotton fibres are hydrophilic — they absorb sweat and hold onto it. Polyester fibres are hydrophobic: instead of soaking up moisture, they move it along the surface of the fabric through capillary action, spreading it out so it evaporates quickly. This is the principle behind moisture-wicking sportswear, and it's why a polyester shirt can feel almost dry even mid-match.

For tennis specifically — a sport of repeated explosive efforts over one to three hours — this isn't a marginal gain. It's the difference between a shirt that regulates your body temperature and one that fights it.

What happens to a cotton shirt during a tennis match?

Three predictable things, in order. First, it absorbs: within 20–30 minutes of real play, cotton starts holding sweat against your skin. Second, it gets heavy — a saturated cotton tee noticeably weighs you down and shifts around as you serve. Third, it chafes: wet cotton is abrasive, and long matches in a soaked shirt are how players end up with raw skin on shoulders and nipples.

There's also the recovery problem. On a changeover, a polyester shirt starts drying immediately in the sun. Cotton stays wet, which feels cold when the wind picks up — exactly what you don't want between sets.

Polyester vs cotton: how do they actually compare?

Is polyester alone enough — or do you need spandex too?

Pure polyester wicks well but can feel restrictive during a full service motion. That's why the best match shirts add elastane. The PrimeFit Match Tee and the premium Predator Tee (€65) both use a 90% polyester / 10% spandex blend — enough stretch to move with an overhead or a stretched forehand, while keeping the fitted shape that serious players want.

If you're comparing match shirts and training shirts, the fabric logic is the same but the priorities differ — we broke that down in practice shirt vs match shirt. For sessions where you'll sweat through everything anyway, the TrainWell Training Tee (€39) is the workhorse option.

When is cotton actually fine for tennis players?

Cotton has its place — just not between the lines. It's the better choice for travel to the courts, the clubhouse afterwards, and everyday wear, where its softness and breathability shine and sweat volume is low. A simple rule: if you'll break a sweat, wear polyester; if you won't, wear whatever you like.

One care note for polyester: wash cold and skip the tumble dryer and fabric softener. Softener coats the fibres and blocks the wicking channels — the most common reason a good performance shirt "stops working."

What fabric is best for high-performance tennis shirts?

The best fabric for high-performance tennis shirts is a polyester or polyester-spandex blend — like the 90% polyester / 10% spandex fabric used in the Vexo PrimeFit Match Tee — because it wicks sweat, dries fast, and holds its shape, unlike cotton.
