ASSOS MILLE GT Spring Fall LS Jersey C2 — Endurance Thermoregulation

Layerable endurance warmth for cool-weather distance riding.

The MILLE GT Spring Fall LS Jersey C2 is built for the rider who measures days in hours, not laps. Reengineered with increased insulation and a less restrictive cut, it delivers stable thermoregulation across the +12°C to +20°C window — the cool, variable temperatures of spring and autumn endurance days where the weather refuses to commit.

Why riders choose it

• Brushed thermal main fabric (Insulation 3/5) — More heat retention than the EQUIPE R sibling, tuned for steady-state pace, not max efforts. Pain point: pure-race jerseys run cold on long, easy endurance rides. Benefit: consistent warmth from kilometre 5 to kilometre 150.
• Regular endurance fit — Less compressive than blackSeries race cuts, with room for a baselayer or arm warmers underneath. Pain point: race-fit jerseys won't accept a thermal base when the morning starts at 8°C. Benefit: true layering flexibility for long rides where the temperature swings 10°C between dawn and noon.
• Three rear pockets + zipped valuables pocket — Sized for real all-day carrying: bars, a rain shell, a multi-tool and your phone. Pain point: shallow pockets dump contents on rough roads. Benefit: secure storage you don't have to babysit on broken tarmac.
• Drop-tail rear hem with silicone gripper — Extended coverage over the lower back when in the riding position. Pain point: short hems expose the lower back as the ride goes long. Benefit: full coverage and zero ride-up across 4+ hour days.
