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. Assos iJ.tiburuUno Jacket DetailBecause 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.

Reviews & Community

How is this jacket different from the intermediate jersey?

Think of the Intermediate as the best long sleeve jersey out there, and the TIBURU as the best long sleeve insulator jacket out there. The TIBURA has better protection against the elements and much warmer. Give me a call - happy to help out:)

Is this jacket good for riding in drizzle and light rain?

The Tiburu feels more like a medium weight jersey rather than a jacket. It is not designed to be water repellent. It's OK in a light drizzle but it's best to carry a light weight rain jacket in your pocket and use that over the Tiburu if the rain hits. I have 2 of these and this is my favorite long sleeve jersey. Hope this helps you.

As sexy as it looks

  • Familiarity: I've used it several times
  • Fit: True to size

I'm 5'10', 155, with a 39in chest and upper arms that are larger than traditional cyclists. I got the Medium. It's snug in the chest, barely enough room for a base layer, but it stretches nicely and the arms and shoulders are perfect, not too tight. The fabric is super comfy. My only complaint is that the bottom zipper fitting is small, not easy to use with gloved fingers. I predict the zipper will be the first thing that will wear out, but hopefully not very soon!

True to size...but could size down has good stretch ability without sacrificing its strong points...pls take note U will need a windproof base layer when necessary very warm JERSEY !

FYI; I'm 5' 8.5" 161 lbs, 32" waist 41" chest, muscular trim physique...I have this Tiburu.4 in size large. Race fit on me. I can wear a light weight base layer under the Tiburu, but nothing else. More of a jersey than a jacket. A bit flashy looking but great piece of clothing.

2nd question on Assos IJ.Tiburu.4 Jacket, what is the temp range, i.e., warmth down to 35 degrees, 45 degrees, etc?

Best Answer

This jacket has a rating of 4, Fall, in Assos' Clima Range. Meaning 60-50F, maybe cooler temps with a baselayer. I would take the Clima Range as a guideline though since cold sensitivity varies from person to person. See: http://www.assos.com/en/44/als.aspx

38/40-60f ( lighter or heavier base layer )

how is it washed?

Best Answer

I wash mine on the delicate cycle in a front loading machine. Drip dry. If I pull it out before 7 pm it is completely dry by ride time the next morning.

It wil last longer if hand washed.

Tiburu

  • Familiarity: I've put it through the wringer

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.

I noted with interest that you refer to this as a jersey while Competitive Cyclist calls it a jacket. Is it more like a jersey or a jacket? How's the wind resistance? Thanks!

It wears more like a long sleeve jersey, but is warm like a jacket. (Think arm warmers for your torso). It's not really wind resistant like dedicated soft/hardshell jackets, but for hard training rides that's a good thing. I always find that wind resistant clothing gets too hot when I'm riding hard. With a light base-layer, I use it down in the 40s, and I've been comfortable returning from rides when it got back into the low 60s. If there's a particularly cold wind or I'm riding easy I just throw a wind vest on and it's perfect. I prefer the flexibility to add or remove wind-proof layers, rather than being stuck with one thing. Murphy and the weather always team up to bite me on that one.

That's been my experience, as well. 60s it gets pretty warm for me, but 40s and 50s it is also my favorite jersey—I don't call it a jacket either!

I've never worn the intermediate on rides, but have tried it on. Fits similar, but didn't feel like it would be as warm as the Tiburu. I have since bought a second Tiburu because I wear it so much now that I moved back to a colder climate.
