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.

Before going any further, it's worth noting that we tend to disagree with most manufacturers' temperature recommendations. That's not the case with Assos. The Swiss brand recommends the bonka in temperatures ranging from 32 to 41 degrees Fahrenheit, and—except for the especially cold-hardy or cold-prone among us—our use pattern generally falls within those guidelines. The blend of certain materials in certain areas suit the jacket perfectly for the mid-30s, and strategic layering pushes it easily into sub-freezing temps.

Like the airJack, 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, which keeps the chill at bay with separate windproof and insulating layers. 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.

TwinDeckFoilling's inner, insulating layer is Assos' RXQ fabric, a lightweight stretch fabric that's smooth on one side and fleecy on the other. RXQ is myopically focused on retaining body heat, so it doesn't do much in the way of blocking wind and rain; however, given the dual-layer construction, it doesn't have to. RXQ maintains a warm microclimate against your skin while strataGonUltra protects that microclimate from the external elements.

Since they don't see the elements as much, the inner-arms and side panels 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 in an area that, frankly, can benefit from those exact properties without risking too much by reducing wind resistance. The back panel consists of RX fabric, a heavyweight thermal material that insulates, ventilates, and breathes well because it lacks the windproof membrane housing the front panels' RXQ. By positioning wind-blocking material up front and thermal material in back, Assos creates a cocoon of warmth that lets your body heat itself up, allows for plenty of breathability to fend off clammy chills, and prevents the cold air from cutting into your core on the leading edge.

The bonka also features a few new tricks compared to the airJack. Including extra shaping at the elbow for greater comfort and a stabilizing hem in the rear. It also conceals an additional thin, insulating gaiter between the shoulder blades—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. In the low-30s, the gaiter deploys to keep your nose, jaw, and neck warm; otherwise, you can keep it tucked away in its own secure strap. The Mille suffix indicates that Assos has longer, more relaxed rides or heavy winter layering regimens in mind for this version of the bonka: Mille indicates that it's cut according to the brand's more accommodating regularFit. If you're looking for the over-the-top, skinny Euro fit, try the Cento version.

Love it. Go to Jacket

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

workmanship is typically ASSOS, top notch. Size, I am 6 feet, 175 pounds, athletic build 6% body fat, 40 inch chest, 30 inch waste. I bought a mille-large and it fits perfect. No flapping Use a mid-weight base layer under it with no issues. Ride 2-3 hours in temps between 30 deg and 40 deg ... comfortably warm. Is OK below 30 deg with a heavy-weight base layer if you are pushing hard and generating body heat.

Best jacket ever

  • Familiarity: I've put it through the wringer
  • Fit: True to size
  • Size Bought: Medium Mille

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
  • Size Bought: medium and large

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
  • Size Bought: XL

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

  • 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

  • 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.
