ASSOS MILLE GT Women's Indoor Bib Shorts S11

**New ASSOS Fall/Winter 2026 Collection item

ASSOS MILLE GT Women's Indoor Bib Shorts S11 are based on the ASSOS MILLE GT endurance bib short platform, women specific and adapted for indoor training with an ultralight, ultra breathable, fast-drying construction.

The MILLE GT Bib Shorts S11 are rider favorites for a reason. They’re comfortable, they’re breathable, and they last for several annual seasons of long-distance abuse. There is one calendar season where they don’t excel, though: Winter. So we adapted everything that you love about them for indoor training, giving you the ultimate endurance bib shorts to see you through the cold months while spinning in-place on a training app. Though ASSOS is calling them “Indoor,” these bibs also thrive in the hottest summer conditions – in that case,  sunscreen is recommended under the ultralight leg panels. The construction combines the same textile on the standard GT S11, QUARTZ, with targeted panels of the open-structure POLSTAR, which we use on our TACTICA liner shorts. The pair of textiles balance reliability and durability in high contact areas with impossibly lightweight breathability and cooling on the leg panels. The bib straps are also lighter, using a perforated mesh to maximize cooling airflow and the GT S11 insert situates a breathable, cooling Sundeck section up front, where shock-absorbing support isn’t needed but added airflow is more than welcome.

FEATURED FABRICS
The QUARTZ textile is a lightweight, breathable warp knit with permanent odorControl – the same used on our standard, proven GT Bib Shorts S11. The true-black color doesn’t turn white or become transparent while stretching during normal use, and 80% of its content is from pre-consumer recycled polyamide. The legs are wrapped in POLSTAR, a bi-stretch, ultrabreathable cooling mesh with a hydrophobic treatment that pushes moisture to the surface and speeds evaporation.

CONSTRUCTION/FIT
ASSOS streamlined regularFit and body-contoured shaping reduce seams, eliminating friction for total comfort and easy layering.

ENGINEERING
//X-Frame: A suspension design originally engineered for the Racing Series. Limits sag on the lower back, stabilizing the insert and main body panels.
//PILtec Plug-In: A lightweight, ultrabreathable textile band across the leg opening. The microdot silicone treatment is invisible from the outside but stabilizes fit and maintains grip in wet or dry conditions.
//zeroPressure Waist: A soft, highly elastic waist construction that improves comfort and hold at the waist, minus any pressure or pinching.
