The Assos iJ.haBu.5 has the fit, comfort and lightness of a jersey, but the insulation and protection of a jacket, making it an ideal outer layer for chilly winter and spring rides. It's versatile enough to be a suitable three-season cycling top.

The iJ.haBu.5 has actually been a staple of the Swiss clothing brand's range since 2010, but this limited edition green colour is a new option. The jacket is designed for what the company describes as 'early winter', but the quoted temperature range of 6 to 14°C probably gives a better indication of what that means.

Assos develops its own fabrics. This jacket uses Stratagon Light windproof fabric on all the front-facing panels (chest and front of the arms) and a Roubaix RXQ everywhere else. The Roubaix fabric has a fleece waffle pattern, which provides insulation and means it's soft next to the skin.

The two fabrics are thin and lightweight yet very breathable and insulating enough to make this a versatile top – it can be used in a wide range of temperatures. Just choose the appropriate baselayer, from a short-sleeve one for double digit temperatures and a chunkier long-sleeve layer for cold rides. In my experience, provided the riding pace was of a suitably high effort, it's good down to about 5°C.

Neither of the two fabrics used in the jacket is waterproof, but the front panels are water-resistant. They'll deal with a light shower, but any more than that and you'll want to reconsider your outfit, or throw on a waterproof jacket.

Where this jacket really impresses is in the fit. It's excellent. Assos has been making high-performance cycle clothing for a long time and it certainly shows. It's generous enough around the torso and shoulders so as not to be restrictive, and the length of the collar, arms and waist is spot on. The fabrics used provide enough stretch to provide good freedom of movement, all helping to deliver the great fit. The waistband is lined with a chunky elastic band and it keeps the jacket in place and stops the pockets sagging even when loaded.

Around the back are three regular sized pockets with two extra zipped ones. Together, all five provide plenty of cargo space for a decent length ride. It's always nice to have a zipped pocket to stash the house keys or mobile phone, and two zipped pockets is even better. Nice work Assos.

There's an additional pocket on the right sleeve, which could be used to place an iPod, with the necessary holes and loops for the headphone cable.

The iJ.haBu.5 is a versatile jacket. It provides enough insulation for all but the coldest rides, and it's breathable and light enough to work well into spring, with careful adjustment of your baselayers. It's an ideal three-season jacket and the sort that can get a lot of use throughout the year. It's also not showing its age at all, and stands up to competition from newer rivals.

It's available in a wide range of sizes and a choice of colours if the green here isn't to your liking. It certainly commands a high price (though shopping around reveals some decent discounts), but it delivers excellent performance on cold, dry days.

Update: We had some comments on social media about the risk of crashing in an expensive jacket being, but Assos tells us it offers a crash replacement policy where. If you crash within one year of purchase and the garment can still be repaired, they will do so, free of charge (with the exception of damages to inserts and lenses). 

Furthermore, Assos will replace any garment within the first three months if there is any manufacturing defect, no questions asked. If the garment is older than three months, Assos will evaluate a case individually in terms of repair.

Great jacket, but, I think, just a bit left behind now. It's decently warm, but not overly so. It's not really good with damp weather.  There are lots of better all rounders.

I bought the original version some years ago and it is my favourite 5-15°C jacket for not-wet condition.

I've had one for about 5 years, have worn it extensively and it still looks like new.  I agree that the technology is a bit behind (am thinking of clothing using Gore's technology in particular such as the Castelli Alpha jersey and the Gabba of course) but I don't feel that matters when something works as well as this.  

It's just a great piece of early Spring & Autumn riding kit and the fit is fantastic.
