Fit is really snug but that’s what I was after. Only used it once on a cold and windy day with a winter jersey underneath and it kept the wind out perfectly, not a hint of cold. Now I have no excuse to stay in when it’s cold... as for the rain though...

Gabba Jacket Review

This gabba jacket is top quality. Designed for winter use without being loose. Very aero. Stylish cut of the fabric. If it was made by a different brand, it would retail at 4 x the price. But nothing feels cheap about it, if anything the exact opposite. Can’t fault it, standard is top notch. I’ve recommended it to all my training partners.

Great jacket , though sizes are small so go up at least one size! Wore now two or three times and mix and match with base layers , best jacket owned to date. Good in dry and in showers, no down hors yet, but so far loving it !

2nd time purchase & the collar fit is good

This is my second review of this jersey (see "Decent jersey but hampered by poor fitting collar") and I'm happy to report that the issue I experienced with the collar must have been a one off - the collar on this version fits perfectly. I've just given it a torture test of sorts - hill training in the peak district at 8ºc and drizzly conditions and it performed fantastically - it kept me dry and also totally protected from the wind during the descents. Sure I had to open it up when really working hard but I would with similar Fiandre or Etxeondo versions of this type of jersey at twice the cost. If it were available as a short sleeve jersey (or half sleeve jersey) with matching arm warmers in the same material it would be a genuine 5 star product - just a little more versatile and suitable for training in slightly warmer weather. Hopefully decathlon could make this happen for spring :)


Great fit and very comfortable. A bit sweaty if the weather warms up during your ride. But... the weatherproofing on mine came away from two of the panels after the first wash (30 degree, delicate wash). I will buy another, as they are on special offer at the moment and never wash it.

Almost perfect Spring/Autumn jersey

Compared to other equivalent jerseys, the price is fantastic. This has been my go to top since February. I have done a couple of 120 mile trips in this top and its been very good. Some feedback for the designers is that the pockets are just too small. When you are out all day, its a bit of a pain to have to leave stuff at home because it wont fit in the pockets. The arms are a little long and baggy considering how tight the rest of the top is, but its not like I am time trialling in it. Overall, I'd recommend this to someone looking for a Gabba style top without wanting to spend loads, and I would be very interested to see what updates are made to this product in future.


I really like BTwin products and so I 'm disapointed to write a negative review for the Aerofit 900 jersey. The fit is fantastic and it looks really good. However, while not being particularly windproof, the jersey also isn't very breathable. For a relatively thick garment it's also quite cold.The result is that while I've heated up and got really sweaty and clammy on climbs, the wind has cut through on the descents or flats leaving me uncomfortably chilly, even with decent base layering. I've worn it twice, in 5-10C temperatures. I haven't tested it in heavy rain.

Dear Sir,
Thank you for feeding back to us your experience of using this jacket.
I have forwarded your comments on to the product manger in charge of this top.
I would be very keen to find out how you feel the jacket performs in wet weather.

You'd think this was made by rapha

Looks great when it's on. dead slick. Works an absolute treat as well. I would suggest you move up from your usual size as it seems to be made for pro cyclists who are stick thin.

Super produit, impermeable et...

Super produit, impermeable et respirant. Des annes sue je cherchais un tel rapport qualité prix. Attention à bien essayer avant d'acheter. Je prends S ou M en temps normal sur des vêtements vélo, sur ce produit, j'ai pris du L et suis très ajusté! Sinon une poche étanche est presente ainsi qu'un trou pour laisser passer un fil d'écouter. Je recommande à 100%

Peu chaude et taille bizarrement

Je suis déçu de par cette veste, initialement prévue pour des temps froids. Je l'ai testé lors d'une sortie (5°C) mais malgré les épaisseurs recommandées, j'ai eu très froid. De plus, le fit de l'article est étrange et ne va pas du tout. Très déçu

Merci d'avoir pris le temps de nous laisser un avis sur ce produit. Je suis navré que l'expérience vécue avec ce produit ai été décevante. Comme mentionné dans une réponse à un précédent avis client, cette veste a été conçue pour rouler sous des températures de 5 à 15 degrés, et éventuellement sous des conditions pluvieuses. Bien-sur, en fonction de l'intensité à laquelle vous roulez et votre sensibilité au froid cette veste couvrira des plages thermiques plus ou moins étendu en fonction des profils. 
Si la description que je vous ai fait du produit ne correspond pas à celle que vous avez eu en magasin, c'est en effet que vous avez été mal conseillé. Si c'est le cas, je vous invite à vous rendre en magasin afin de vous faire échanger cette veste contre une veste qui convient d'avantage à votre pratique.
Voici les vestes qui conviendrait d'avantage à votre usage :

Je prends en note votre remarque et je vais modifier la fiche produit afin que cette information ressorte d'avantage.

Bonne journée,

Additional Product Information


Main fabric : 83.0% Polyamide, Main fabric : 17.0% Spandex

The purpose of a cycling jacket

The third layer is the layer that protects you from the elements, for instance the cold and the wind, while the underneath layers offer warmth and breathability. By wearing a suitable cycling jacket, your performance and comfort will be constant, regardless of the weather conditions. This very light 900 jacket is perfect for intensive use and provides good protection from the wind, rain (it is water-repellent) and cold.


A product's ability to offer protection from the cold. It depends on the material's thermal resistance and how much air can pass through it. The higher its thermal resistance, the more the product retains the heat produced by the body while cycling. This jacket provides excellent thermal protection in spring/autumn when it is always difficult to find the right balance between warmth and breathability. Developed in collaboration with a professional team.


To determine whether a fabric is breathable, we measure its evaporative resistance (test based on standard ISO 11092). The lower its resistance, the more the fabric will let water vapor produced by the body escape, and therefore the more breathable it is. For example: RET < 9 = extremely breathable fabric.


Waterproofing is a fabric's ability to prevent rain water from passing through. A fabric's water-repellency is its ability to make water bead and/or run along its surface. The garment soaks up little or no moisture, dries more quickly, and doesn't become heavier. Water repellency can also make it more difficult for its outer surface to become dirty. Water-repellency is obtained by applying a treatment to the fabric's external surface.

Product tests

Our team of product designers based at the B'Twin Village in Lille, France is continuously working to make cycling more comfortable for our users. Our mission is to create products that meet the specific cycling needs of our users so as to eliminate obstacles that prevent a good riding experience.
