Assos Mille GT Ultraz Winter Jacket S11 EVO

The Assos Mille GT Ultraz Winter Jacket S11 EVO is Assos's top-tier answer to riding through genuinely harsh winter conditions, built as the flagship piece in the Mille GT Ultraz lineup. Where a standard winter jacket asks you to compromise between warmth, wind protection, and breathability, the Ultraz EVO applies three different weights of Assos's NEOS softshell textile across the jacket, mapped to where the body actually needs protection on the bike. It's available through RA Cycles in Golden Yellow and Blackseries.

The front and upper-back panels use a NEOS Light plus RX Heavy double-layer twinDeck construction — a 3-layer windproof, breathable softshell with a PU-bonded membrane for water-repellency — placed where wind and road spray hit hardest. The sleeves step up to NEOS Ultra plus 652.RX for maximum protection in the most exposed position on the bike, while the back panel runs a lighter NEOS Medium softshell, since the back needs less wind-blocking and more breathability once you're generating heat on a climb. The result is a jacket that concentrates its heaviest, warmest material only where it's earning its weight, rather than applying one uniform fabric everywhere.

The cut is Assos's regularFit — trim through the body but roomy enough to layer a base layer or light insulation underneath for the coldest days. Raglan-cut sleeves merge into a stitch line that runs up to the neck, keeping the shoulders and neck free to move through a full range of motion in the riding position instead of binding up on the drops. At the waist, Assos uses a 2W waistWave stitch construction that preserves the natural stretch of the front panel's fabric without relying on elastic, so the fit holds through a ride rather than sagging or riding up.

At $460, this is a serious investment in cold-weather riding rather than a jacket for the occasional chilly commute — it's built for the rider who's still logging real miles once temperatures drop into genuinely uncomfortable territory and needs a shell that performs the whole way through winter instead of just looking the part.
