Assos Mille GT Indoor Bib Shorts S11 Black Series women’s

The Assos Mille GT Indoor Bib Shorts S11 is the Mille GT endurance platform adapted for indoor training. Indoors the riding wind that normally cools you disappears, so sweat becomes the biggest comfort problem. That is what this bibshort is built around: ultra-light, extremely breathable and fast-drying, with an anatomically shaped pad.

The quoted range sits above 21 degrees, which means the shorts also work outdoors on the warmest summer days.

Assos Mille GT Indoor Bib Shorts S11 at a glance

• Breathability 5 out of 5: the highest score Assos gives, exactly what you need without riding wind to cool you.
• QUARTZ main fabric: light, breathable knit with permanent odorControl against musty smells after sweaty sessions.
• POLSTAR cooling mesh on the legs: bi-stretch mesh with a water-repellent treatment that pushes moisture to the surface and lets it evaporate faster.
• GT S11 pad with Sundeck: a breathable, cooling section in the pad that carries heat away where it builds up fastest.
• Fast drying 5 out of 5: dry again quickly after a session, even if you are on the trainer day after day.
• X-Frame suspension: stops the back panel from sagging and keeps the pad stable in place.
• zeroPressure waistband: soft and very elastic, so no pressure points on your stomach in the upright position you take on the trainer.
• PILtec leg finish: light band with silicone micro-dots that keeps the leg in place, even when the fabric is wet.

Built for training without riding wind

Outdoors the riding wind cools you continuously. Indoors it disappears and your clothing decides how much heat and moisture you lose. That is why the QUARTZ fabric is as light and open as possible, with POLSTAR cooling mesh on the leg panels: bi-stretch mesh with a water-repellent treatment that pushes sweat outwards instead of holding on to it. During an hour-long interval block that is the difference between shorts that turn clammy and heavy and shorts that do not.

Comfort on the trainer

On a trainer you barely shift on your saddle, so you keep loading the same points. The GT S11 pad is designed for that, with a Sundeck section that breathes and cools instead of trapping heat. The goldenGate 2.0 construction lets the pad move freely with your pedal stroke, so no fixed folds form that start to chafe.

Fit and finish

The regularFit is body-hugging and meant to be worn for hours at a time. The zeroPressure waistband spreads pressure across a wide area, which is welcome in the upright position you often take on the trainer. The PILtec leg finish keeps the legs stable without squeezing.

Good to know

This is a summer and indoor short: insulation scores 1 out of 5 and there is no wind or water protection. For outdoor rides below 21 degrees, choose a short with more insulation or a bibtight. The QUARTZ fabric is colour-stable, which is useful because an indoor short goes through a lot of wash cycles.

Material composition: front panel, back panel and gusset 84% polyamide, 16% elastane; legs 77% polyamide, 23% elastane; pad 85% polyester, 15% elastane.

Frequently asked questions about the Assos Mille GT Indoor Bib Shorts S11

What makes this an indoor short?

The fabrics and the ventilation. The main fabric is lighter and more open than on a normal summer short and the leg panels are made of cooling mesh, because indoors there is no riding wind to cool you. Breathability and drying speed both score 5 out of 5. Outdoors in the heat the shorts work well too, but on cooler rides you will miss the insulation.

At what temperatures can I wear them outdoors?

Assos quotes above 21 degrees. That is genuine summer weather, because insulation scores 1 out of 5 and you cool down quickly, certainly on a descent. For spring and autumn, a short with more insulation is the better choice.

What makes the pad different from that of a normal bibshort?

The GT S11 pad has its own shape and a Sundeck section that adds breathability and cooling, exactly where heat builds up fastest. The pattern is anatomically built, so the straps and the waistband fall in the right places. That matters more on the trainer than outdoors, because you barely change position there.

Will the shorts smell after hard training?

The QUARTZ fabric has a permanent odorControl treatment that sits in the fibre and does not wash out. That helps most indoors, where you leave more sweat in the fabric than you do outside. Washing is still needed, but the shorts are less prone to musty smells.

Can I use them outdoors as well?

Yes, above 21 degrees. They are then an outright warm-weather short that lets a lot of air through. Bear in mind that there is no protection against wind or rain, so for changeable weather you are better off with another short from the Mille GT line.
