A versatile layering essential for cool, wet, and variable conditions, updated with a new softshell textile and a body-mapped, highly elastic fit that eliminates flapping material without restrictive pressure.
The GTS Vest S11 unlocks three-season layering versatility. Its breathable construction and targeted protection add warmth to rainy summer rides, and its stormproof and thermoregulating qualities protect against the cool, wet conditions of the shoulder seasons. The new CORE Light softshell situates a waterproof, windproof membrane across the shoulders and chest, supported by the high stretch and midweight insulation of LITHIUM Medium across the belly. The combination yields complete protection on your body’s leading edge with a restriction-free fit across the stomach. Raw-cut cuffs eliminate volume for layering over the GT Spring Fall Jersey C2, and a lightweight, extremely breathable rear panel modulates internal temperature to prevent overheating in variable conditions.
Features
- CORE Light is part of the new CORE softshell family, the successor of our AIRBLOCK-EVO family. It combines a four-way stretch warp-knit, a breathable membrane, and an ECO water-repellent treatment to shield against precipitation and wind while expelling internal moisture with a silky-soft lining. LITHIUM Medium is a highly breathable, highly elastic insulator with a grid texture that actively expels moisture and modulates internal temperature. SENS Air Plus is an ultra-breathable, lightweight warp knit that actively modulates internal temperature.
- Our streamlined regularFit provides comfort for long training rides and cool-weather base miles, with the GTS line increasing aerodynamics for added performance.
- Double Slide Zipper: A two-slider construction that allows easy access to pockets and ventilation from top or bottom.
- Raw Cut: Race-inspired construction that eliminates hems and ridges on the armholes for clean lines, boosted aerodynamics, and low-volume layering.
