Item # AAS001Q

A legend is born

The Assos airJack was the jacket that changed the rule book for cycling apparel. Combining a windproof front panel with an exact fit, the airJack was a weatherproof masterpiece that skewed the line between jersey and jacket. Well, times have changed, the competition has gotten smarter, and Assos realized that it was time to step up the airJack's game. Going back to the drawing board, Assos has managed to revolutionize the cycling world again with the successor to the throne, the iJ.bonka.6 Mille Jacket.

Like the older top, the bonka is partially windproof, partially not. That's how it gets the climaRange.6 designation, which is considered to be the above-freezing temperatures of winter. The chest and arm panels that face the wind take advantage of Assos TwinDeckFoiling to keep the cold at bay. It has two layers, one windproof and one insulating. The outer-layer is the strataGonUltra material -- Assos' new waterproof, breathable, and flexible membrane that's less breathable when cold and more breathable as the air directly next to the membrane heats up. This allows it to retain more heat when you're cold and to be more breathable once you heat up and start to sweat. The inner-layer is Assos' RXQ fabric, a lightweight stretch fabric that's smooth on one side and fleecy on the other. The inner-arms are made from strataGonMedium, a lighter, stretchier, and more vapor-permeable version of the Ultra. This material provides both a better fit and more enhanced ventilation. The Medium is also found on the side panels. The back panel consists of the RX fabric, a heavyweight stretch fabric that's alternately smooth and fleecy. And the bottom hem, in the back, has Assos' rear stabilizer to hold the jacket in place.

The bonka also does a few new tricks. There is extra shaping at the elbow for greater comfort. An additional thin insulating layer at the collar —doubtlessly inspired by the many cyclists who borrow 'neck gaiters' from the ski drawer to help keep their necks warm on the coldest of days—seals out the elements. Assos has longer, more relaxed rides in the mindset for the MILLE, incorporarting the regularFit tailoring for this jacket. If you're looking for the over-the-top, skinny Euro fit, try the Cento.

The Assos iJBonka.6 Mille Jacket is available in the colors Black Volkanga, Red Swiss, and White Panther. It also comes in six sizes from Small to TIR. The jacket falls into Assos' climaRange.6, or in non-Assos-speak, winter. By Assos' calculations, you can expect total protection in temperature ranges from around 32 to 41 degrees Fahrenheit.

Superb fit and quality

  • Familiarity:I've put it through the wringer
  • Fit:Runs small

I have this jacket in both Small and Medium sizes. The Medium gives me room for a heavy weight base layer needed for riding into the 30s. The Small is for riding in the 40s with a thin base layer. This jacket is warmer and more breathable than the Castelli Alpha which I also have.

Best jacket ever

  • Familiarity:I've put it through the wringer
  • Fit:True to size

This is absolutely the finest winter cycling jacket I've ever owned. The workmanship has to be seen to be believed. There are so many different fabrics and different panels cut to create the perfect fit.
I've worn this on sub 30 degree centuries with a mid-weight base layer and been perfectly comfortable. It's not yet been cold enough in Connecticut to require a really warm base with this jacket and surely it would have to be brutally cold, sub zero, to ever require more than a heavy base layer.
The retail is steep on this but you really do get what you pay for.

good for me down to 38

  • Familiarity:I've used it several times
  • Fit:Runs small

3 wool icebreaker 200 wt shirts and fugu pants with built in vests makes a medium too tight for me, with i shirt a medium fits me so I have one large and 1 medium
if it had more give in circumference I could use one size
exceedingly good otherwise

Warm and Fashionable

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

Showed up for a group club ride and everyone thought I was there to race. Jacket fits slim but comfortable. I am 6' 1" so an XL is my size in Assos gear. For a day that started at 32 degrees, average 41, I just wore the jacket and early winter Assos base layer. Needs body heat to warm the air insulation so you start out cool. Warm to a sweat as soon as the 6-7% grades start. Like all Assos gear, it's expensive but worth it it for fit and quality.

succinct and to the point on all issues; size, layering, temp and use. the kind of review we always want.

Superlative

  • Familiarity:I've put it through the wringer

I was a bit skeptical of the other reviews, but no longer. I'd give it more stars if I could.



It fits like a glove. (I'm 5'10", 165 lbs, 40-41" chest, and I got a large.) It breathes perfectly, and provides the right amount of warmth no matter what effort.



I've ridden it from 20 degrees up to 50+, and I just use the appropriate amount of layers. (I use Craft).



I think the style is cool, and all the writing on the zipper cover is interesting as well.



The only down side is the face mask that is sewn into the back. I found it to be pretty unusable. It's like a balaclava with out the head covering. Because of this, it doesn't really stay in place. I just (carefully) cut it out.



Still, if you ride often in cooler weather, this is a piece of technical clothing that really is technical and does perform.



Buy it.



Hi. Are you sure you got the Mille? About to pull the trigger but I have minor sizing concerns. Your review and input are very helpful.
Thank you !

A Life-Changing Cycling Garment

  • Gender:Male
  • Familiarity:I've put it through the wringer

I can not add any comments about the brilliance of this jacket and all Assos gear that has not been said many times by many others. I wish I could give it six stars. I've taken this jacket down to 15F with two base layers and never felt cold or damp. It is actually thicker than I was expecting. I was afraid it would be just a shell but it is more than that. It feels like wearing a second skin.

The back pockets are larger and more easily accessible than I expected as well.

Sizing:

I misunderstood the sizing chart. I am 6'1" and about 200 pounds and my chest measurement was about 43-45 inches and I ordered an XLG. The XLG was too large when standing and ridiculously large when in a riding position. I returned the XLG and got the XL. The XL is tight when standing and "clicks in" when in a riding position to be very comfortable. So the numbers listed in the sizing chart under "Chest" refer to the *minimum* size for your chest measurement not the upper limit. The length is fine too.

Update (Feb 26, 2015):

I have been using this jacket daily in January and February putting in about 20 hours per week. This winter in the Northeast US has been bitterly cold with daily average high temperatures around 20F with 10-20 mph winds. I have taken this jacket out down to 10F and up to 40F. I use Assos base layers (early winter and winter plus) to achieve this. The jacket is truly amazing. I have virtually never felt cold anywhere even after riding for three hours in these conditions.

This is what I have learned: Keeping your core temperature up means your extremities will be fine.

Someone commented about the neck warmer. It is a little tight for me and so I too have trouble getting it to stay in place on my face. It is suppose to go from lower neck to over your mouth and nose. I find it slips off my mouth and chin after several miles and just covers my neck. I use a balaclava over this and all is well. If you don't use the neck piece then it stores in a loop on your back on the inside. I only use this to cover my neck and not my face if I am also wearing a hat. Otherwise I just store it and do not notice it.

I have washed it several times so far using Woolite on the gentle cycle, inside-out, and zipped, and let it air dry. I've had no problems of any type. If I do not wash it, then after a ride I simply leave it inside out to dry and have had no problems.

I now look forward to cold riding conditions.

You get what you pay for

  • Familiarity:I've put it through the wringer

I purchased this jacket last fall specifically for fat biking on our local single track during winter. It's been fantastic from subzero temps (with a couple base layers) to high thirties with a lighter layer. Also ideal as a cold weather road riding jacket since it blocks 100% of the wind.



The fit is excellent and the fabrics function as advertised to regulate heat and moisture while I'm working hard on long climbs at lower speeds. I frequently use the built-in balaclava which is very handy and stays in place well on colder rides.



If you buy for this piece, you won't be disappointed. It's worth the price of admission.

Best winter jacket ever

  • Gender:Male
  • Familiarity:I've put it through the wringer

12/2013: I got this to replace an 11? year old 851 Airjack. It is slightly warmer, and I have already gone down to 20 degrees F with 2 baselayers. Above freezing I ride with one Craft layer only. I am 66.5 inches, 38 inch chest, and 150 pounds and went with the small Mille cut over the Cento. My old 851 was more of a Cento cut. This jacket has some extra room across the chest and arms while standing but is perfect on the bike. No flapping in the wind. I probably still could have gone with the Cento without issue.
Better windproofing seems to be the biggest change from older desighs. I have not used it above 45 degrees and suspect it would be too warm for me at that temperature. I have yet to get clammy or wet despite very hard efforts. It breathes perfectly whether riding tempo or freewheeling home after a long winter slog. I haven't needed to pull out the emergency built in balaclava yet but its nice to know its there. Wish it came in more color choices is my only complaint.

12/2015: 2 years later still greatest winter jacket ever. Looks new without stains and all stitching intact. Very durable. Wash in Woolite, completely drip dry in 10 hours. Sadly it is now Team Assos on group rides, it is a go to piece for everyone in the know.
