Assos Uma GT Half Shorts S11 Info
The Assos Uma GT Half Shorts S11 are built for the rides where bib straps aren't the answer. Hot days when the sun is relentless, indoor training sessions, or casual coffee shop rides where you want serious chamois performance without the full commitment of bibs — that's the specific territory these shorts own. Assos took the GT insert platform and engineering they're known for and wrapped it in an ultra-minimalist, bib-free design that doesn't compromise on where it counts.
The body is constructed from QUARTZ textile — a lightweight, breathable warp knit that solves one of the persistent problems with black cycling shorts: it maintains a true-black color under stretch and doesn't go white or transparent during normal use. It also carries permanent odorControl treatment and is made from 80% pre-consumer recycled polyamide, which keeps the weight down without sacrificing durability. A band of Sens AIR across the lower stomach adds targeted breathability and stability in the front panel, eliminating pressure when you're in an aggressive position on the bike.
The waist system is where the engineering gets specific. hipClick combines elastic and mesh layers with a high, unrestrictive rise to keep the shorts locked in place and the insert positioned correctly throughout the ride. zeroPressure Waist adds a soft, highly elastic waistband construction that holds securely without pinching. At the leg openings, PILtec Plug-In uses an ultrabreathable textile band with invisible microdot silicone grip that performs the same in wet conditions as dry — meaning the shorts stay put whether you're sweating through a trainer session or pushing into a summer headwind.
The GT S11 insert runs 12mm thick — an endurance-depth platform. The Mono12 Shock-Absorb Damping System uses thermoformed compressive foam layers to reduce ridges and hot spots. The 3D Waffle construction is a patented three-layer perforated foam that increases airflow through the chamois and eliminates excess weight. goldenGate 2.0 provides a free-floating construction that moves with the body rather than against it, with redesigned wing cut-outs that reduce friction across the full pedal stroke. A new ultralight front panel adds additional cooling airflow where heat builds most during hard efforts.
