Assos iJ.tiburu.4 Jacket $268.95
The marriage of jersey and jacket
Our first full-zip long sleeve jersey was made by Assos. It was a closeout, and we felt pretty savvy for the purchase. But, expectantly, the top lasted and lasted. It was our go-to long sleeve jersey for a decade, and a few years in, we realized that the jersey would've been a bargain at any price. That old jersey was a direct ancestor of this iJ.tiburu.4 Jacket.
In Switzerland, the tiburu is a spring and fall jacket -- they call it climaRange 4. Depending on where you live, it's a jacket that works from early fall, through winter, and into late spring. Further breaking down the funny-sounding name, the iJ stands for Insulator Jacket, meaning the material is fleecy and warm on the inside -- a heavy jersey if you will. Because you have to strike a balance between being cool and hot, the jersey uses RX fabric for the front panels -- both the chest and the parts of the arms facing the wind. It also uses the lighter RXQ for the back and the inside of the arms. This mix helps protect the body from the wind while allowing some heat to escape where the wind can't get to you.
The iJ.tiburu.4 also takes advantage of a technology that we've only seen thus far in Assos' jerseys -- a rear stabilizer system that's been highlighted by the gripper across the back under the pockets. This means that the pockets won't bounce or sag when they're full. This a welcomed cross-over feature, and one that we hope to see more and more often in the future.
Also standard fare here are the three rear pockets with one extra zippered pocket on the right side for valuables. There are reflective tabs sewn on the seam that join the pockets to the top.
The Assos iJ.tiburu.4 Jacket are available in the colors Black Volkanga, Red Swiss, and White Panther. The jacket also comes in six sizes from Small to TIR.

Like most people, I was quite put off by the price of most everything in the Assos line. I tried numerous other long sleeve jerseys from other companies but always found that the fit was off, it didn't breath well, or didn't really offer any warmth. I enjoy my long, cold, winter training rides and needed a top that could cover a pretty broad range of temperatures throughout the day and be comfortable the whole time. In my opinion the Tiburu is the perfect top. I've done long easy rides, threshold climbing days, cold weather group sufferfests and everything in between. I've never had one complaint. It's my go to jersey when the weather gets below 60 and with a light rain/wind jacket I've ridden in snowstorms in the mountains. When finances allow I'll be getting another one because I'm getting sick of hand washing it every day so it's ready for the next ride.
