Spatz Coolr Baselayer

Olympic-Level Thermoregulation. Aero Jersey Integration.

The engineering hallmark of the Spatzwear CoolR Baselayer is its advanced 75% Coolmax™ moisture-channeling knit paired with an ultra-close, zero-crumple aero profile. When riding under relentless summer sun or grinding through stagnant indoor turbo sessions, sweat trapped against the skin leads to rapid overheating and core fatigue. Spatzwear selected a technical multi-filament Coolmax™ blend that pulls moisture away through capillary action, accelerating evaporative cooling while feeling practically weightless against bare skin.

Why the Spatzwear CoolR Belongs in Your Kit Drawer:

• Olympic Champion Proven: Conceived and engineered specifically to meet the high-ventilation demands of Olympic-level road and track athletes.

• Specialized Coolmax™ Fiber Matrix: 75% Coolmax™ PES weave actively wicks sweat from the skin to speed up evaporative cooling and eliminate clammy fabric cling.

• Aero-Jersey Optimized Silhouette: Form-fitting, painted-on race cut lies completely flat under modern, tight-fitting aerodynamic jerseys without crumpling, rolling, or bunching.

• Dropped Rear Tail Hem: Extended lower back panel remains securely tucked inside bib shorts, ensuring complete lumbar coverage while in an aggressive riding position.

• Engineered Multi-Season Versatility: Designed to perform dual duty providing essential evaporative cooling during sweltering outdoor summer climbs and handling heavy sweat volume during brutal indoor trainer sessions.

• Premium Portuguese Craftsmanship: Knitted in Portugal with subtle, in-weave Spatzwear branding and soft-touch flatlock seam construction to prevent chafing during long hours in the saddle.

The Alegro Perspective: In high-heat conditions and indoor trainer workouts, a lot of riders make the mistake of ditching their base layer entirely, thinking one less layer keeps them cooler. In reality, a bare skin-to-jersey interface just traps a layer of boiling sweat. The CoolR acts like an evaporative pump: the Coolmax™ fibers pull moisture away from your body so your jersey actually vents it. It sits razor-flat under tight skinsuits and race jerseys, and it turns brutal indoor turbo intervals into something you can actually push through.
