Excellent jacket

Great jacket for the price, I couldn't find a similar product for less than £160 from other companies. Great fit, great colour and really warm. I won't shop anywhere else for cycling clothing.

Deep winter warm jacket

I have warn my jacket today for the first time and its great warm, breatherable and fits great, on completion of my ride I have noticed a manufacturer fault on the reflective shoulder section, I would not expect this for a top end jacket of this type. I have a photo of the problem

Poor quality

Bought last years model of this jacket and although I was initially impressed with the value for money, after only 3 or 4 wears the zip has recently torn off in a normal wash cycle.

Hello. Thank you for the feedback. This indeed is not acceptable so please do visit your nearest store or contact our Customer Loyalty Team to organise an exchange of the jacket or a refund (you have 365 days for either). We will review the jacket zip to check for any defects.

great jacket

I have last years blue jacket and used it last winter and like it so much so have bought this years new black colour. This jacket or jersey whatever you call it is an excellent piece of kit. It enables me to get out in the winter and stay warm and that is worth a lot. Fit wise I am 59 and fairly serious cyclist have a size large am 6 foot 2. 34" waist long arms and slim build and jersey fits snug but not tight or restrictive. It is made of a nice stretchy fleece material has a built in liner hood which seems gimmicky but try it and you soon realise that it works a treat . The back length is nice and long and splash proof. thre's a waterproof phone pocket,pump loop pocket etc and the jersey neck is comfortable. All in all I have many top brand clothes but this is the one I reach for if the weather is inclement.

good jacket but not perfect

This is a useful, attractive and well priced jacket with the integrated balaclava/waistcoat. The arms are long and are a neat fit. The chest too fits well. The back is curiously short making the rather small pockets rather high on the back, but hey tights are always very high, so no real problem. Good thermal/wind blocking qualities. I live in northern Scotland and it is great for from +4 down .....and down...and down.

Great Top, excellent value

40 years experience riding in English winters, this is a great bit of kit and at such a reasonable price

A great jacket

It kept me warm and chilly for 3 hours in the chilly Chilterns. I did a 3 hour ride on a cold foggy December day and it kept me toasty and dry. The pockets are nice and deep to keep phone, keys etc safe.

My Favourite Top

I would not normally want to spend this much money, but thought I would see what you get for your money. I have not been disappointed. I feel (and hope I look!) like a 'proper' cyclist wearing this. Its bright, and had excellent reflective shoulders, so I feel visible without wearing hivis yellow. It keeps me warm with just an Aerofit base layer, on chilly days, and on colder days I attach the inner jacket, which adds another layer, with the option of the built in balaclava if its really freezing.

Chaqueta de ciclismo càlida y transpirable.

Te protège de temperaturas 0 grados y, al mismo tiempo, no te empapa por el sudor cuando le estás dando fuerte. La pechera y el tapabocas de fábula, menos cosas que llevar u olvidar. Falta un bolsillo más grande para los móviles actuales. No recomendable para mtb, los enganchones con las ramas la perforan. La recomiendo al cien por cien.

Additional Product Information


Main fabric

  • 100% Polyester cationic


  • 85% Polyamide
  • 15% Spandex

The purpose of a cycling jacket

The third layer is the layer that protects you from the elements, such as the cold and the wind, while retaining the warmth and breathability properties of the lower layers. This base layer helps you keep up your performance and stay comfortable in any weather. This Aerofit jacket will keep you warm thanks to its neck warmer and removable breastplate. Ventilation openings ensure perspiration escapes.


A product's ability to protect 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.


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.

Care tips

Machine wash at 86°F. Synthetics cycle. Turn the article inside out. Use a minimal amount of laundry detergent. Do not use fabric softener. Line-dry in a warm, ventilated area. Do not tumble dry. Do not dry-clean. Do not bleach. Do not place on a heater to dry.
