EQUIPE RS LS Jersey S11

EQUIPE RS LS Jersey S11

Assos's WorldTour-proven race jersey receives long sleeves in the S11 generation for continuous aerodynamics – almost like a skinsuit – and light protection in mild conditions. The sleeves made from 550CX fabric actively direct airflow and thus reduce drag, while the body made from miniCheck Tex delivers ultralight, highly breathable comfort with UPF 25. At the back, the Stabilizer V11 panel provides hyper-cooling; it's so light (UPF 15) that the manufacturer recommends a layer of sun protection underneath for sunny days. The racingFit fits like a second skin, dries quickly and is optimised for use at temperatures above +21 °C – ideal for fast training sessions and races in the Swiss summer as well as mild days in spring and autumn.

• Back panel Stabilizer V11 for hyper-cooling (UPF 15)
• Triple Ramp Pockets with stabilising "Lids"
• PILtec Plug-In hem gripper for secure hold – even when wet
• Raw-cut, bonded hems and zip for clean transitions
• racingFit with compressive, skin-tight fit
• Sizes XS–2XL and multiple colour variants

Technical Details and Features

The long sleeves are made from the newly developed, warp-knitted 550CX material, which fits bi-elastically, wraps around the muscles and channels airflow in a targeted manner with its textured surface. The front uses miniCheck Tex with high elasticity and distinctive ASSOS texture, while Stabilizer V11 at the back stabilises the pockets and allows heat to escape quickly thanks to its extremely low density. Constructionally, raw-cut and bonded finishes are used on sleeves, hem and zip to keep transitions smooth and minimise turbulence. Integrated Triple Ramp Pockets secure nutrition and gilet even during rough riding, and the rear hem is reliably anchored by PILtec Plug-In with silicone micro-dots. Material-wise, the manufacturer specifies 90% polyester/10% elastane at the front and 80% polyester/20% elastane on the sleeves – a mix that balances breathability, support and aerodynamics. Independent tests of the S11 platform jersey confirm the aero-optimised sleeve structure and skin-tight fit for race pace.

Applications and Benefits

This long-sleeve jersey plays to its strengths wherever speed and efficiency count: on fast road bike loops around Lake Zurich and Greifensee, during summer races or on long Alpine passes with intense sun exposure. The full-length sleeves combine aero advantage with additional sun protection, so you can do without arm warmers without sacrificing speed. The racingFit remains stable in every position, while PILtec Plug-In fixes the fit during attacks, sprints and in corners – even when the fabric is damp. Thanks to Triple Ramp Pockets, you stow bars, gels and a light gilet securely without the pockets sagging. For particularly sunny days, some sun protection is recommended under the back panel, as Stabilizer V11 is designed for maximum cooling.

If you value a precise fit, the racingFit offers a very compressive, skin-tight cut that feels perfect on the bike. Sizes range from XS to 2XL; refer to your usual ASSOS size and choose according to desired compression. The jersey is available in various colour variants such as Deep Petrol and Almond Milk as well as occasional special editions (e.g. team designs), which makes coordination with existing RS kit easier. As a retailer, we recommend light base layers underneath for the Swiss summer to further optimise moisture management during high-intensity efforts.
