Pleasantly surprised

Bought this jacket as it was reviewed favourably against the eyewateringly priced but widely respected market leader (the one all the Pro's wear!). At almost a 1/4 of the price this is an excellent piece of kit in mild winter weather (I haven't yet tested it in more harsh conditions). I wore it for the first time on a 5 day bike packing trip along the Croatian coast in mid December.(6-17C not accounting for wind chill) Breathability & wind proofing (together with a thin long sleeve base layer & arm warmers) was very good. I can tend to feel a bit overheated when putting in max efforts and layered up but this was not the case with this jacket. As for it's performance in wet weather I have only used it in light showers but to my satisfaction. I would like to see it available in brighter colours as this is only available in Black and I would prefer something that would be more visible to other road users. In all a good product at a very reasonable price.


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.

BTwin Aerofit

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.

Great Jacket for cold weather

has wear it first time during in the cold last weekend which was 0°C , i has wear it with my base layer and it's prefect and it's keep me warm during 4 hours spin, it's was cold at the first few mins cycling until body temperature start to warm up.

Fällt zu klein aus

Bei normalen Shirts trage ich eine S (178cm, 65kg), bei Decathlon muss ich allerdings bei sämtlicher Lauf- und Fahrradbekleidung eine M wählen und bin damit immer zufrieden gewesen. Dieses Radtrikot liegt allerdings so eng an, dass es um die Taille schon ein wenig unangenehm ist, sowie es mir durchaus ein wenig kurz vorkommt, besonders wenn man sich auf dem Rad nach vorne beugt. Daher empfehle ich eine Nummer bei der Größe nach oben zu gehen. Mir würde hier eine L sehr gut passen. Davon abgesehen macht das Trikot einen sehr guten Eindruck, habe es nicht ausgiebig getestet, da ich es aufgrund der falschen Größe wieder zurückgeschickt habe.


Passt soweit top, nur die Ärmel könnten am ende elastisch sein

Additional Product Information


Main fabric

  • 83% Polyamide
  • 17% 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.
