Verdict: 
Great fit and style from a jersey that performs nigh-on perfectly on sunny days

Great fit and style comes from a wool-based jersey from Isadore – called the Woolight – and it's nigh-on perfect for sunny days in the saddle. Maybe you're off to the Continent...

Isadore pitches its products to the higher end of the market, priding itself on creating sleek designs using the best materials for the serious and stylish cyclist. That much is clear from this jersey, and it more than delivers in terms of performance too.

Moisture-wicking is extremely good thanks to its merino wool blend (you'll find 23% merino and 77% polyester in this jersey, hence its name), and so remains comfortable to wear whether you've just gunned it up a steep climb and are getting a real sweat on, or just out for a gentle spin around your local flatlands – in which case the warmth afforded by the wool comes into play very effectively.

It's equally at home in the very warm conditions it's been designed for as well as cooler mornings, and the merino fibres also offer the added benefit of UV resistance.

The fit, as you'd expect with a product that's had input from the Velits brothers (Martin rides for Etixx-QuickStep, Peter for BMC), is close and performance orientated, coming up slightly smaller than your average fit. That said, it's not racy, so you can very easily ride at a casual pace in a more relaxed position on an endurance bike or commuter/cross bike without a problem. The hems are all well thought out, with the cut ensuring a good fit around the arms, and the waistband has some styled grippers integrated to minimise excess movement around your torso.

Perhaps slightly surprising to us is the flexibility of the jersey; it truly is one of its best qualities, and with ample pocket space for a couple of bars, gels and spares, including a zipped compartment for valuables, it never leaves you wanting on hotter days.

All the while, you look good on the bike too. Interestingly, this 'jet black' jersey really isn't black at all; it's actually a dark green colour. This becomes most apparent when worn with a black pair of bib shorts, and also features lighter green highlights in the zip and at the hems of the pockets. The effect is pleasing, and I'd argue that it looks better than it would if it were truly black.

Additional design features include a reflective tab on the back as well as signature-style metal Isadore logos: one attached to the pockets, and another to the neckline. This has the effect of making the jersey look seriously flash – you wouldn't look out of place hanging out in the most fashionable areas of your locale. There's even a loop incorporated to keep your earphones tidy... a nice nod to the racing heritage of the Velits siblings.

Finally, through the wash the jersey stands up very well, the 77 per cent polyester adding strength and longevity to the fabric in addition to the technical benefits of merino wool. No threads have come loose, and putting it on after a few washes still feels like wearing it for the first time – and you can't say that about many jerseys out there.

All these features and top quality in fabric and construction mean the jersey isn't cheap. Currently the RRP comes in at the equivalent of £77.27 (€105) – but for the technology involved, and the performance it gives you, it's well worth the investment as one of your best lightweight summer jerseys.

The Woolight jersey does begin to get into the territory of Rapha, Castelli et al for cost, but with performance like this it's genuinely worth considering.

77% polyester means it is going to stink pretty much just as quickly and as bad as 100% polyester (based on my experience with a 50/50 merino/polyester jacket).

Just to say that contrary to the above , I own a number of both short and long sleeve Isadore tops and I cannot say that they smell at all. I don't wash them as often as other tops as they just don't need it - almost odourless. All the tops I own are really very comfortable and wash well. Worth every penny and you don't look like some prat who is trying too look like someone who he's not.

So wearing 'certain' cycling clothes makes you a prat!? Not really full of the love of cycling brother/sisterhood then are you

I'm sure Isadore love you as a brand ambassador.

I agree and apologies - silly comment. Thought the review was thorough and objective.

I have a lot of both merino and Marino & polyester blend clothing and I don't find the latter smell bad at all.

If anything I prefer high tech polyester for hot days because they wick sweat much better.

Interesting. I sweat bucket loads, and I ultimately went with merino because it does much better at managing the sweat for me. Also, merino seems to cope a bit better with a wider temperature range for me.

Horses for courses.

I own the white version and can honestly say I don't get wiffy when out on a hot day (the only hot day we had this year). It is a very comfy jersey with well placed pockets, easy to access ( I have the Rapha Super lightweight which is a good top but pockets are too high IMO).

The pure merino does cope much better in wide range of temperature especially when the temperature dips.

But put it to the test of both and you will find that you will be much drier if you go with good polyester in hot weather (HH). For really hot weather the Castili mesh jersey is just amazing. With merino you will find the entire jersey wet but with Casitili you will find yourself to be near bone dry.

I love my merino when it is under 10C.
