Assos Spring Range : Mille GT Jersey and Vest

The Tiburu is dead, long live the Mille GT Jersey.

Right, rewind for a minute. You’ll remember the Assos ij.Tiburu insulator jacket which, confusingly, isn’t really a jacket at all, just a cold condition winter roubaix jersey. Well, that’s pretty much gone now and been replaced by the Mille GT Spring Fall LS jersey. But, be careful with your google skills, because there is also a Mille GT Summer LS jersey as well. So it’s worth setting out what Assos offer for spring, fall and summer conditions just so you don’t get confused.

The Mille line is becoming Assos’ staple, go to, everyday cyclist line. And that suits me just fine. So, we have a roubaix lined long sleeve for cold days in the Mille GT Spring Fall, a long sleeved version of the Mille GT short sleeve jersey for cool summer days, and then, arguably, the Mille Intermediate Jacket for the colder spring fall days (the one with the windproof front). The Falkenzahn gilet has been replaced by the Tiburu Gilet and there’s now a really stripped back gilet to partner the Mille GT range in the shape of the Mille GT Gilet. Today I’ll be looking at that combination, the spring fall LS and Gilet.

So, the Mille GT replaces the Tiburu. On the scales it’s lighter. The Tiburu was never a jacket but it was a really good cold condition jersey. Partner it right and you could get away with some pretty cold temps. The Mille GT feels noticeably more lightweight, especially at the rear, which I’ll come back to. So the big question is how well it copes with cold temperatures. Most of the time I have to wait for some to arrive, but it’s got ten progressively colder over the last week so I’ve been able to look at days of 12 degrees right down to morning starts at zero. I won’t be using this combo next week. It’s not really going to be able to deal with the threatened -12 windchill. That’s Mille winter jacket time. I’ve a Fugu Face balaclava coming too.


The Mille GT is a noticeable departure in design style for Assos. Gone are the arm shapes of the Tiburu with something a bit more ‘sobre’ but still with a defining brand aesthetic in the shape of the Assos logo patterned arms. The front of the jersey is made from Assos’s own RX fabric, a fleecy lined thermal fabric. It is a bit more shiny than the Tiburu was and I have to say, I like it a lot. The inner arms are of a more breathable fabric. I spent a while (!) feeling the front of the Tiburu and Mille. There’s not much in it. The Tiburu might be slightly thicker, but I suspect that Assos’ own advances in tech mean the new Mille is just as warm.

The arms are, for want of a better description, normal. There’s nothing all that clever at the termination, it just works. Sleeve tightness is comparative with the overall fit of the jacket, that is to say, bordering on race fit. The cut here is Assos’ Mille regularFit. I’ve said that their Mille range allows me to size down. But, here, Mille regularFit is slightly between the Mille and ‘rest of the range.’ So, with that in mind, I take an XL in this (and the vest later) rather than the L I take in the Mille winter and intermediate jackets. It’s looser than the old Tiburu (in XL) but only slightly so. There is, I feel, more room in the back on the new range.


The back is made of an Assos’ proprietary fabric called Stripe. Essentially a breathable lightweight mesh. This is a departure from the slightly heavier rear of the Tiburu. It’s a lot more breathable overall. The back of each colour (the range is black, blue or red) is all black. That’s a good choice in terms of road grime.


There are reflectives on either side to aid visibility at night. The pockets are a little different to before with Assos saying that ‘our triple ramp’ concept pockets to secure your essentials.’ And, I have to say, they really do. They fall open a little better than before, they are sufficiently deep and you can load them with a lot of stuff.

My first ride in the jersey was with a Craft baselayer and no Vest. Temperatures were about 8 degrees and it performed very well. Clearly, there is no windproofing so you will always feel some cold on your chest on a fast descent. But that’s what the baselayer was there for (it’s windproof). My second ride was at 13 degrees. I got rid of the baselayer to see what it was like in those temps. It was spot on and, I reckon, you could easily wear this sans base layer up to 20 degrees or so. Without a base layer it’s very comfortable. One thing I’d like to really mark out as outstanding is the neck. When shoulder checking in traffic etc it was noticeable how not noticeable the neck was. Zero irritation and perfect height. It’s the little things that stand out. My final ride without the vest was in temperatures of around 5-6 degrees with a slightly warmer base layer and, again, it coped very well with all of that. It won’t do rain, naturally. And if it’s really windy, I’d put something over the top. But, as a lighter replacement for the Tiburu, I reckon it’s a bit of a triumph. And there’s the kicker. Cost. The Tiburu was knocking on the door of £200 RRP. This isn’t. It’s £120. Factor in some discount from ‘your favourite online retailer’ and that might be £110 or £100 or so. It’s a lot, but factor in the build, warranty back up and outright comfort, and this is a very impressive jersey. And yet another example of Assos bringing down their prices to more achievable levels. It’s very very good.


One of the things Assos do so very well is layering. So, even though the ALS moniker has disappeared from the design (Assos layer system) Assos still ensure that their stuff works together. And, if you were in any doubt, here’s the Mille GT Vest on top of the Jersey.


The length, width, height of everything is the same. The overlap of zips is well thought out. The neck section doesn’t feel like too much. Indeed, that comfort of the jersey neck is not diminished in the slightest by the addition of the vest neck. It snaps together beautifully.

This is no Falkenzahn though. It’s definitely been cut down. And that’s not necessarily a bad thing.


The Vest is, pretty much, the Jersey duplicated without sleeves. So you have that fleecy lined front face with the lighter breathable fabric at the rear. The waist gripper locks onto the outside of the jersey and keeps the combo in place. You can’t have your red jersey protruding beneath your black gilet! The colour combos are the same too, red, black and blue. I chose black just in case I got another of the jerseys, and, on that question, I almost certainly will. I suspect it will be really good on cool summer mornings partnered with the GT Summer LS, or SS plus arm warmers. Stowability is average, this is a protector not a lightweight emergency jacket. But it can be folded and stowed.


Round the back sound differences to the Falkenzahn/Tiburu become apparent. There are no pockets, Assos taking the new approach to have openings. That would be doomed to failure if no thought were taken of matching up the lines of the jersey underneath but, of course, they’ve done that. Will it work with all jerseys? It might be less easy but the opening is sufficient stretchy to get into fairly easily. The removal of the pockets makes it lighter, more breathable and lessens the pressure of additional fabric on the lower back. In addition, items are stored ‘internally’ and gain a bit of protection.


The arms are elasticated and should cater for all shapes and sizes. Sizing is identical to the equivalent jersey with perhaps a mm or so additional provision for being ‘over the top.’ The zip is excellent and the design of the shoulders carries forward the sleeve design of the jersey. It’s a fantastically well thought out combo. RRP is £100, which is about half of what the Falkenzahn was and £70 cheaper than the Tiburu Gilet. If you don’t want double layer fabric then a windstopper Mille GT vest is available for £85 with most of the same features.

The combination of jersey, vest and suitable base layer have taken me down to 0 degrees on a fast paced run. I’d not spend 6 hours outside in those temperatures but it’s certainly doable with the right bibtights, gloves and headwear. Each item could also be used as a base layer in its own right underneath the Habu or, heaven forbid, Mille winter jacket. If you were doing the latter, it may be an idea just to stay indoors.

To my mind the Intermediate S7, Tiburu and Falkenzahn were real gems. They were all something different. But they were never cheap. And these ‘replacements’ in the Mille Intermediate, Mille GT Spring Fall jersey and vest, could hardly be called budget. But you could have each of them in two colours for the price of the old holy trinity. Comfortable, hard wearing, superb warranty back up, stylish, reasonably priced. Choose 5.
