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.

With the lower thermal ability, this product fares best in autumn, spring and during milder days in winter. However, it may not do so well in warmer conditions, as the breathability is not brilliant when putting in big efforts.

The key feature, and the one that can be the difference between an enjoyable ride and distinct discomfort, is waterproofing. It is here that the Aerofit 900 does well. While testing this jacket in intermittent heavy showers, it was reassuring to see the rain drops beading on the surface of the fabric and being blown away by the gusty wind. The jacket isn’t entirely waterproof, only water-repellent, but this is far more protection than is provided by a standard jersey.
