Great Jacket strange cuffs
Love this jacket perfect for rainy days in Ireland which we get a few. The cuffs on sleeves are not made of the same material and seem to be more absorbent which leads to water getting inside gloves and cold hands and wet wrists. Strange choice on what is a great jacket. With most clothes im a medium 86kg 176cm. but in all Isadore jackets im a L limited stretch so M gets tight on chest. so id size up.Show full review -

Nice fitting waterproof jacket
I have been looking for a while for a jacket that fits well (not too lose) and this fits well. The sizing is in keeping with Isadore's jersey sizing's. It is designed to fit whilst in the riding position and that is what it does, so it does feel a little tight across the shoulders when standing upright. Having a 2 way zip is also a plus , making it easier to get stuff out of my jersey pockets on the moveShow full review -

Great waterproof
This is a great garment for being on the bike. The only glitch is that the fit is not great when you are walking off the bike and not bent forward on the handlebars.Show full review -

High quality
181cm 88kg ordered large. The fit is a bit tight in my chest when standing up straight but is perfect when on the saddle. A larger size would give more room but I’d worry about the arm length. I also figure me losing a bit of extra weight this season will help. The material is great and blocks the wind well. Fits in a jersey pocket without issue. I haven’t had to use it in the rain yet. Maybe this week. As it’s been too cold to risk riding in the rain since I got it.Show full review -

Good perfomance, strange size
I am 184cm \ 78 kg. Took L size, but it's really long at the sleeves. Need to cut smth like 10+cm. Everything else is fine. If I would take M size, it can be so tight fit, because of shoulders. So, I consider this jacket having so narrow shoulders, but long arms. For perfomance, it's really good breathing, didn't tested waterproofnessShow full review -

Super Rain Jacket
This review takes place after a few uses. Perfect in rainy conditions, I stayed completely dry. I'm 178cm and 68kg, wearing Size S fits good for a sporty position on the bike. If I'm in an upright position (eg standing) the front side is too short and the front part of the shoulders is too tight.Show full review -

Super Versatile Jacket
Superb craftsmanship quality, zips, suture etc... Material is very pleasant to the touch, and is very comfortable during the ride in wind or rain. Jacket is very useful during colder autumn mornings and in colder misty or rainy weather as top layer on softshell jacket. 10/10 for this product, worth every euro !!!Show full review -

Schmal geschnitten
Musste die Jacke auf XXL umtauschen da ich breite Schultern habe, dadurch sind die Ärmel sehr lang. Ansonsten super Material und angenehm zu tragen. Hat aber noch keinen Regen gesehen.Show full review -

Tolle Jacke, nicht nur bei Regen
Habe die Jacke in Sudan Brown gekauft. Sie sieht in real um einiges anders aus, als auf den Bildern. Wie ich finde, um einiges besser. Weniger Orange. Habe sie bisher bei einer Regenausfahrt getestet, alles blieb trocken.Show full review -

A superb piece of kit. Other positive reviews are completely right. One thing is, the sizing is correct. This jacket is tailored for the on-bike position only. This is really important to accept. Go on your bike and check if the jacket sits proper. It will.Show full review -

Top Regenjacke, habe sie bei Graupelschauer um 1 Grad getragen. Bietet einen super Schutz vor Nässe und Wind. Passt in eine Rückentasche. Ich musste umtauschen, hatte zuerst Größe M bestellt. Trage nun bei 181cm und 77kg Größe L . Das passt bei dem was man im Winter ohnehin schon so drunter hat.Show full review -

Reliable, lightweight, good fit
I had a chance to test this jacket in a rain - and it is really waterproof :-) it is water repelent so the water drops are swept away right ahead. It is also very light, you can pack it into the back pocket of your jersey. Right now, I am using it also in the chilly mornings to protect against the cold breeze. The size also fits pretty well as I am not 100% cyclist body prototype :-)Show full review -

Looks great but fragile
I got this in Sudan brown and it looks absolutely amazing. Unfortunately the pocket where you pack it in is glued, not sewn, and it got ripped apart pretty easily.Show full review
