Assos Mille GT Spring/Fall Knickers



Superb fit, comfort and warmth for three-season cycling

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

It's that time of year for covering up the skin to keep warm on chilly rides, and a really good choice for autumn and early winter are three-quarter-length shorts. These Assos Mille GT Spring/Fall Knickers are a really good example of the genre, with a superb fit, warmth and comfort that makes cycling through inclement weather a breeze.

  • Pros: Comfortable, warm, fit,
  • Cons: Not as versatile as bibs and knee warmers

The Mille GT knickers (or three-quarter-lengths – 3/4s – as we prefer to call them around these parts) are based on the bib shorts of the same name, but the fabric extends to below the knee to provide the right protection when it's too warm for tights but too cold for shorts.

I know 3/4s aren't for everyone, some people can't see the point of the halfway house approach, but I know many who favour them over shorts and knee warmers, or even full-length tights unless it's perishingly cold. Personally, I often go straight to leg warmers, such is the unpredictability of our weather, but I've found a new love for 3/4s. Their use can also be extended into three-season wear too, for cooler summer rides.

Assos has long been known for its premium prices, but the Mille GT range is aimed at providing a lower entry point into its clothing. The price is still reassuringly high, though you can pay a lot more, but you're getting a lot of experience and top quality design here. Still, they need to deliver.

And that they do. Comfort, fit and warmth are all first class. In fact, I found the comfort exceptional. Pulling them on really is a luxurious experience, the soft lining feels lovely next to the skin. They feel like they were custom-designed for me.

The fit is perfect, snug everywhere it needs to be but not taut where it doesn't want to be. It's a slightly compressive fit, but more relaxed than Assos racing attire.

Warmth is ideal for current temperatures, though they can deal with sunnier weather too. They're made from two weights of insulated fabrics. RX Heavy does the heavy lifting when it comes to insulation and is used on the front panels, with added water-repellency to protect in showers, while the back is made from RX Light, which helps warm air escape and adds extra stretch for fit and comfort.

The shaped panels and articulated legs ensure the fabric sits very nicely over the knee. There's no restriction when pedalling, no bunching of material, and after a few miles, they fade away. I found it a lot more comfortable than wearing knee warmers with shorts, or the added weight of full-length tights.

The length has been well judged: nicely below the knee to avoid irritation in this area when pedalling, but not so low that you have that weird tiny gap between them and socks. Reflective details have been added to the back of the legs to help you stand out on gloomy training rides or commutes.

Saddle comfort comes from the Assos Mille S7 Evo padded insert. It features a plush 8mm of memory foam with a 3D waffle perforated foam and 'goldenGate', which involves the sides of the pad being detached from the shorts for extra freedom of movement.

It sounds like a complex design but it's stupendously comfortable. The chamois is a big part of the Assos appeal, and – silly names aside – this one delivers comfort for mile after mile. It doesn't feel bulky and stays dry on warmer rides. The pads used to be pink, but they're now black which is a bit more practical.

Wide stretchy bib straps converge into a mesh back panel, and the front of the shorts comes up a little higher than some but still provides easy comfort breaks.

These are great shorts with superb comfort, fit and warmth. They are quite pricey, though, and they lack the versatility of shorts and knee/leg warmer combo and the protection offered by full-length tights. Their window of use during autumn and spring could be long or short depending on the variables of the UK weather, but when the weather window is right, nothing quite beats them.

Durability should be good too. I've got a 10-year-old pair of Assos 3/4s I still wear when the weather suits, which is a good innings. That's good, because they don't come cheap.

There aren't many we've reviewed to compare them with, perhaps showing how out of favour 3/4-length shorts are at the moment, but they are twice the price of the Primal Dawn Men's Bib Knickers, which got a brilliant review last year.

They're also £20 more than Castelli's Sorpassa 2 3/4 bib tights.

Size tested: Medium

Tell us what the product is for

Assos says: "Ideal for those cool fall and spring rides where added knee coverage and a touch of insulation make all the difference, the MILLE GT Spring/Fall Knickers are constructed with a blend of ultrasoft and insulating fabrics, paired with our evolved MILLE GT insert. To make a knicker that would meet the demands of these variable conditions, we added two custom insulated textiles to the design. RX Heavy makes up the majority of the paneling-a beefed-up version of our workhorse RX-featuring an ECO water-repellent treatment for further protection from light precipitation. This fabric ensures the fronts of your legs stay shielded from biting winds and cold air, while the backs of the legs are made up of RX Light for added breathability in this high-flex zone. The fit of the MILLE GT Knickers falls into our regularFit category, which means they're lightly compressive where they need to be, but not as tight as our racingFit apparel. The fabric panels flex with each pedal stroke, as they're both pre-shaped and sewn to fully wrap and support the upper leg muscles, knees, and calves while in motion. The insert is our MILLE EVO, featuring 8mm of plush memory foam for dependable comfort on every ride."
