Pre-Order

With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!

Pre-Launch

With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

Estimated Delivery & Collection Dates are given on Pre-Order and Pre-Launch products. They are for indication purposes only and can change at any time without notice.

The dates we provide are based on indications given by our suppliers. Whenever we get updated information from our suppliers we will endeavour to update the Estimated Delivery & Collection Dates provided on product pages.

We estimate this will be ready for despatch to you or collection via Click & Collect on Undetermined

Assos Mille Gt Road Cycling Jersey S11 Evo in Deep Petrol

Season:2026

Brand:Assos

Code:11.20.432.2W

The latest GT Jersey is an everyday staple, engineered to keep you cool, dry, and well supplied on every ride – day after day, season after season. The body textile, AirCell, is the same as the previous generation, but the sleeves now feature Eclipse, a new, impossibly light, and highly elastic textile that wraps your arms in soft, cooling support. The simplified pocket construction still features our cargo-securing ramp design, but the lines are cleaner and the seam count is reduced. In addition to the new spectrum of colorways, the GT S11 EVO also inherits an updated ASSOS logo, first debuted on the Racing Series. Please note: The GT Jersey S11 EVO is so lightweight that we recommend sunscreen beneath the body panels.

The finer details
FEATURED FABRICSThe main body textile is AirCell, an ultralight circular knit with an open hexagon pattern for extreme cooling breathability. AirCell’s bistretch qualities provide elastic, body-wrapping stretch and support, and engineered odorControl maintains freshness during high-intensity efforts. The sleeves feature a new textile, Eclipse, a lightweight warp knit with ultrasoft skin feel and UPF 50+. The ultralight Stabilizer V11 back panel reduces pocket sag, even when fully loaded.

CONSTRUCTION/FIT
Our streamlined regularFit and body-contoured shaping reduce seams, eliminating friction for total comfort and easy layering.
ENGINEERING
Raw Cut:
The sleeves feature a lie-flat construction adapted from the Racing Series for an ultra-low profile that enhances aerodynamics.

Triple Ramp Pockets:
Flexible fabric panels create “lids,” securing and stabilizing pocket contents.
