In September 2019, Assos adds a piece to the Mille GT line that many cyclists will use more than any other: the Airblock Vest. A vest for transitional weather — spring and autumn, when conditions change every 20 minutes.
The material
The front is made from NEOS MILD, a proprietary 3-layer softshell with PU membrane. 100% windproof, water-repellent, highly breathable. Numbers: 260 g/m², MVP 20,000 g/m²/24h, water column over 10,000 mm, 4-way stretch. These aren’t catalogue values — NEOS MILD is a material Assos developed in-house.
The back uses VENTAMESH — a breathable mesh that dissipates heat when you’re working on a climb. In between, in the belly and upper back area, brushed RX material provides light insulation.
A clever detail
The Rear Pocket Slots are two openings at the back that let you access the pockets of the jersey or jacket underneath. It sounds simple but solves a real problem: anyone wearing a vest over their jersey normally can’t reach their bars and phone. With the Airblock, you can.
Assessment
The Airblock Vest isn’t a racing piece — it belongs to the Mille GT line with regularFit, less compression, more comfort. But that’s exactly what makes it an everyday product. A vest you put on at eight in the morning, stuff into your jersey pocket at noon and pull back on in the evening. That’s what it’s built for.
