MILLE GTS 2/3 Vest C2

Assos MILLE GTS 2/3 Vest C2

The Assos MILLE GTS 2/3 Vest C2 – also referred to by Assos as the “Spring Fall Vest C2” – is a windproof and water‑repellent shell vest for cool, damp and windy conditions between summer and winter. At its core is the new AIRBLOCK.888 membrane on the front and sides, combined with a highly breathable VENTAMESH back for a stable personal microclimate on the road bike or gravel bike. The sleek regularFit provides secure coverage without unnecessary bulk and makes the vest especially layer‑friendly over a jersey or midlayer. Designed for the 2/3 (Spring‑Fall) period in the Assos layering system, it is perfectly suited to typical Swiss transition weather – from morning chill to the bise in the afternoon.

Technical Details and Features

The AIRBLOCK.888 membrane is an Assos‑developed, mid‑weight 3‑layer membrane that blocks wind and water while remaining elastic and maintaining breathability – ideal when the weather changes on a pass or across the Swiss Plateau. The VENTAMESH back offers bi‑directional stretch, lies smooth against the body and promotes air exchange so excess heat can escape quickly. The regularFit is constructed from highly stretchable fabrics and comes without bulky waist elastics or finished arm hems, which reduces chafing and simplifies layering. Details like raw‑cut arm openings and a reflective hem on the back increase comfort and visibility in diffuse light. The fabric blend of 53% Polyamid, 34% Polyester and 13% Elastan strikes the balance between protection, stretch and durability.

Use Cases and Benefits

This vest plays to its strengths on long descents, in changeable spring/fall weather or during short showers – classically over a summer jersey or as an outer layer over a thermo jersey. In the city it makes commuting around Zurich or Basel more pleasant; on the road bike it keeps the core reliably protected on Jura ridges and Alpine passes. The combination of front protection and an open back avoids heat buildup during intervals or climbs while still providing effective weather protection on flat terrain. Specialist media generally praise Assos’ Spring‑Fall concept as a successful mix of wind protection and high breathability, underlining its everyday usability in variable conditions. For wet, cold days it pairs sensibly with a baselayer and a long‑sleeve Spring‑Fall top.

Fit, Sizes and Layering Tips

The regularFit silhouette is designed for endurance rides: close to the body but not as tight as a race cut, so there’s room for additional layers underneath. Thanks to the elastic construction the vest sits without flapping and avoids pressure points even in dynamic positions on the drop bars. It is available in XS to 3XL, providing clean coverage for larger riders as well; the sleeveless raw‑cut edges make it easy to put on and take off over sleeves. In the Assos 2/3 (Spring‑Fall) system it works excellently over a lightweight baselayer and jersey; on cool, damp days many riders combine it with a thinly insulated Longsleeve. This keeps the core warm without overheating during efforts.
