This S11 version is more form-fitting, more breathable, and just as protective, the ALLEYCAT S11 is high level race-day weather protection. For the S11 generation, ASSOS upgraded every textile, re-oriented the seams, and created a sleeker fit. The result is a more aerodynamic silhouette that’s proven on the WorldTour and packs down to the size of a fist, ideal for variable conditions in spring and fall or as a final protective layer in winter. The ALLEYCAT leads into the elements with a windproof, waterproof, and breathable 2L membrane across the chest, shoulders, and upper back. That protection is supported by an ultralight, ultra-elastic, water-repellent panel wrapping the stomach and lower back, maintaining protection while eliminating restriction in aggressive, aerodynamic positions.

Technology overview | The finer details
FEATURED FABRICS:
Diamond ULTRA is a highly breathable, water-repellent, and windproof 2L softshell engineered with a body-mapping four-way stretch to maintain aerodynamics. Lower sleeves of 575CX reinforce breathability and a second-skin fit, and a band of the ultralight woven textile MIG across the stomach and lower back sheds water, increases aerodynamics and reduces volume and weight.

CONSTRUCTION/FIT:
ASSOS AEPD 11 racingFit is a second-skin, aerodynamic silhouette designed with WorldTour proteam feedback to envelope the body in 360-degree compression and stability.
