Thermal Barrier 2.4 Men's Thermal Cycling Vest Thermal Barrier 2.4 Men's Thermal Cycling Vest

Why wear this garment

Because it is the result of applying molecular physics principles to thermal design. Its Tek Series® membrane works like an intelligent filter that distinguishes between vapor and liquid: the smaller, more energetically active sweat molecules pass through the microporous structure through osmotic diffusion, while cold air and water are

blocked outside.

This means a dry body, a stable internal temperature and zero feeling of humidity, even during prolonged ascents or on cold and windy descents.

Its ultra-low weight, its high level of elasticity and its Race Fit fit make this vest a second aerodynamic barrier that protects without penalizing performance or generating flare. Ideal for athletes looking for thermal efficiency and real energy savings on every pedal stroke

.

Technology

• Tek Series® bilayer membrane: regulates heat exchange through osmotic diffusion through a vapor pressure gradient.
• Active osmotic management: stabilizes the internal microclimate and prevents condensation.
• High density elastic structure: 73% polyester | 26% polyurethane | 1% spandex; maximum elastic memory and lightness.
• Multilayer functional design: designed to be worn on a jersey that promotes the diffusion of moisture to the membrane.
• Repellent treatment (DWR): keeps the surface dry to preserve osmotic performance.

Technical characteristics

• Weight: 96 g (size M).
• Recommended thermal range: 4 °C to 10 °C (extendable to 2 °C depending on the combination of layers).
• Construction: ultra-light and elastic Tek Series® bilayer.
• Zipper: YKK Vislon double slider with internal windproof protector.
• Double collar with inner strap that prevents contact of the membrane with the skin.
• Self-packing inner pocket for compact storage.
• Armholes with anatomical elastic for perfect fit.
• Race Fit: snug, aerodynamic and flame-free.
• Extended back to prevent splashing.
• Elastic bottom with anti-slip gel.
• Three strategic reflective inserts for low visibility.

Performance-enhancing benefits

• Thermal regulation by osmotic gradient: keeps the temperature stable without internal humidity.
• Weightless thermal protection: only 96 g, ideal for multilayer systems.
• Full elasticity: freedom of movement and precise fit.
• Watt savings and aerodynamic efficiency: tight cut and smooth surface to overcome air resistance.
• Advanced comfort: double collar, soft finishes and internal flap for maximum protection.

More details that make the difference

• It is stored in its own internal pocket.
• Extended back with continuous design.
• Part of Suarez's Thermal Technology multilayer technology, optimized for different cold intensities.
