ASSOS builds its RX textile family in several weights, and the DYORA R Spring Fall LS Jersey S11 sits on the midweight rung of that ladder — warmer than a summer jersey, well short of the RX Extreme used in the matching bib shorts.
The chest, shoulders, and arms are wrapped in the midweight RX textile, a soft, brushed insulator with a durable warp-knit construction
. That placement is deliberate: those are the panels taking direct windchill in a race position, so that is where the brushed insulation goes.
Insulation stops where it would become a liability.
OSMOS Medium extends insulation across the stomach with a breathable, warp knit structure that provides compressive support to stimulate blood circulation.
The rear panel switches to lightweight Stabilizator V11, which locks vertical stretch to prevent sagging pockets and expels excess heat.
Two things happen there at once — the back becomes the vent for heat you generate climbing, and the pockets stop dragging the hem down when you load them. Anyone who has finished a cool ride with a loaded jersey hanging off their lower back knows why that matters.
The cut is the race pattern, not a relaxed one.
The AEPD 11 racingFit is a second-skin, aerodynamic silhouette designed to envelope the body in 360-degree compression and stability.
Size accordingly — this is a jersey meant to be worn over a skin layer and nothing bulkier, and if you prefer room to add a mid-layer underneath you will want to look at a regularFit piece instead. The detailing follows the same racing logic.
A zeroPressure waist gives a secure hold without pinching, the lightweight strozzoKragen collar keeps bulk off the throat, and the rear pockets use a perforated stretch fabric that wraps contents tightly and adds breathability.
The collar is meant to let you modulate your own microclimate without unzipping and exposing your throat to cold air.

Where this fits in a wardrobe is genuinely useful to understand.
ASSOS positions the Spring Fall Jersey as a foundational piece of the DYORA R system — worn alone on cool days, or under a rain shell in wet conditions.
The lightweight rear panel is specifically there to prevent overheating when output goes up or the temperature climbs.
For cool, dry conditions, ASSOS suggests layering it over a skin layer and pairing it with the DYORA R Spring Fall Bib Shorts
,
and dropping it under a DYORA RS rain shell when it turns colder or wet.
Those bib shorts use the heavier RX Extreme textile, so the pairing is warmer on the legs than on the torso — which is usually the right distribution once you are moving.
If you already own a summer race jersey and a winter jacket and find yourself caught out on the shoulder days, this is the piece that closes that gap without adding a third full layer to the rotation. It is built for the same intensity as the rest of the DYORA R line —
a blend of thermal textiles maintaining breathable warmth engineered for racing and high-intensity training
— so it holds its shape and its position at speed rather than needing constant adjustment. The blackSeries colorway keeps it pairing with anything else in the drawer.
