Alpinestars A-Dura Air Jersey – Men's Short Sleeve MTB Jersey, Bright Blue

Alpinestars A-Dura Air Jersey – Men's Short Sleeve MTB Jersey, Bright Blue

The short sleeve summer MTB jersey Alpinestars A-Dura Air Jersey in bold Bright Blue pairs maximum breathability with strong visibility on the trail. The mini mesh knit air mesh construction with fine perforations across the whole jersey delivers airflow even on long rides in the sun, while the lightweight polyester/elastane blend wicks sweat effectively and leaves the body free to move while pedaling or standing on a climb. The chest carries a screen-printed Astars logo, while the back features a large circular Alpinestars Racing Ahead graphic with a central Astars logo. Regular fit and an extended drop tail keep the jersey in place even when leaning over the bars.

Mini mesh knit air mesh construction

Mini mesh knit air mesh is a knit fabric with fine perforations spread across the entire jersey, not just in underarm panels like typical mesh materials. Air passes through the fabric evenly as a result, while the material stays stretchy enough — the elastane content moves with your shoulders and arms, so the jersey doesn't restrict you even when leaning over the bars. The same perforated structure that ventilates also speeds up moisture-wicking, pulling sweat from the skin to the fabric surface.

Lightweight polyester/elastane construction

The jersey is built from a lightweight polyester/elastane blend — low fabric weight keeps the overall jersey light and speeds up drying once you've been sweating, so it doesn't cling to your skin even on a long ride in the heat. The material also resists snagging on branches on the trail without losing its soft feel.

Color as trail visibility

Bold blue across the chest and sleeves sets the jersey apart from the surrounding terrain more than the line's muted colorways — useful on group rides or when riding through denser woods. The regular fit sits closer to the body than a loose cycling jersey but leaves room in the shoulders for movement on the bars, and the extended drop tail stops the jersey riding up when leaning over the bike. The Astars Racing Ahead graphic on the back gives the jersey a bolder look off the trail too.

Season and sizing

The thin, extra-breathable fabric has no thermal lining and is built specifically for hot summer days and long rides in the sun — it's not meant as a standalone layer in colder weather. Sizing reference point: the model shown in the manufacturer's official photos is 187 cm / 6'1" tall and wears size L. We stock S, M, L and XL — if you plan to wear the jersey over a base layer or back protector, size up.

Frequently Asked Questions

What size should I choose?

The jersey has a regular fit, not a race-tight cut. The model in the manufacturer's official photos is 187 cm / 6'1" tall and wears size L — if you plan to wear the jersey over a base layer or back protector, size up.

Is the Bright Blue colorway very bold?

Yes, it's a bold blue, more vivid than the more muted colorways in the A-Dura Air line — easy to spot in a group ride or on trails with denser vegetation.

How should I wash the jersey?

Machine wash at 30°C, inside out to protect the print, do not tumble dry, and don't iron directly on the screen print — this extends the life of both the graphic and the fabric's stretch.

Can it be worn off the bike too?

Yes, the regular fit also works as a training or running top — the air mesh construction ventilates well off the saddle too.
