Ultralight Comfort for High-Output Pursuits

The Icebreaker 125 Cool-Lite™ Sphere III Tank is a versatile, soft, and highly breathable performance top designed to handle everything from grueling summer climbs to casual forest runs. Engineered with Icebreaker's signature Cool-Lite™ jersey fabric, this tank prioritizes moisture management and airflow, making it the ideal base layer or standalone piece for hot and humid conditions.

The magic of this tank lies in its blend of natural merino wool and TENCEL™ Lyocell. While the merino wool provides natural odor resistance and temperature regulation, the TENCEL™ (sourced from sustainable eucalyptus) significantly increases the cooling effect and speeds up drying time. With its refined fit and thoughtful seam placement, it offers a "barely-there" feel that eliminates chafing over long distances.

Key Features:

• Cool-Lite™ Fabric: A technical blend of 60% TENCEL™ and 40% Merino Wool that keeps you significantly cooler than pure wool or synthetic alternatives.

• Natural Odor Resistance: Merino fibers naturally inhibit the growth of odor-causing bacteria, allowing you to wear it more and wash it less—perfect for multi-day trekking.

• Offset Shoulder Seams: Specifically designed to prevent friction and chafing when wearing a heavy hiking pack or hydration vest.

• Drop-Tail Hem: Provides slightly more coverage in the back, ensuring the tank stays in place during dynamic movements or while bent over handlebars.

• Ultralight 125g Jersey: The thin, airy knit provides maximum breathability without being transparent, making it a staple for high-summer performance.
