Assos Mille GT Spring/Fall Long Sleeve Jersey S11

The Assos Mille GT Spring/Fall Long Sleeve Jersey S11 is a midweight cycling jersey for the in-between months, when a summer jersey is too little and a full winter jacket is too much. Assos builds it from a fleece-backed RX thermal fabric, listed at 250g/m² on the front, that is meant to hold warmth while still breathing on climbs and harder efforts.

The Mille GT line is Assos's endurance range, aimed at long days rather than race starts. The S11 update adds room through the chest, which makes the jersey more comfortable in an upright, all-day riding position while keeping a streamlined shape rather than a loose, flapping one. The cut is a regular fit, so it works on its own on a mild day or as a base layer under a gilet or cycling jacket when temperatures drop.

Sleeves are raw-cut, which removes the bulk of a stitched cuff and sits comfortably whether you ride with gloves or without. The fabric is described as fast drying and abrasion resistant, with 360-degree stretch so the jersey moves with you in the saddle. Retailer listings also cite UPF 50 sun protection.

Sizing runs from XS to 3XL, with chest measurements from 88-91cm in the XS to 122-129cm in the 3XL. The jersey comes in five colors: Golden Yellow, Mulberry Brown, Almond Milk, Blackseries and Deep Petrol. It suits long weekend rides, gran fondos and commutes in spring and fall, and works as a mid-layer when the weather turns colder.
