Cycling Weekly Verdict

For the price it's hard to fault this jacket. But to be really strict on the testing criteria, it did let water through eventually and wasn't the warmest once this happened. Still, for 50 quid you can't go far wrong

Reasons to buy

  • +

    Keeps most of the rain out

  • +

    Aero fit

Reasons to avoid

With its own-brand B’Twin range of equipment and clothing, Decathlon always aims to deliver quality at prices far below the competition. The Aerofit 900 long-sleeve jersey follows that design brief: it’s a product worn by the FDJ Pro Team but doesn’t break the bank.

The Aerofit very much lives up to its name, and the body has a very snug shape, though the upper arms slightly flap in the wind. It may be worth going a size up to ensure you’re able to fit more layers underneath; this jacket isn’t particularly warm, despite claiming a 4/5 thermal insulation rating.
