GF23 – Lightweight Performance Tank

GF23 – Lightweight Performance Tank

Size

Designed for movement, breathability, and everyday performance.

A clean, technical tank top built for active use, training, and warm-weather movement.

GF23 is made from Polartec® Power Wool™ lightweight fabric, combining the natural performance of merino wool with advanced synthetic fibers. The result is a tank that feels light on the body, never restricts movement, and performs exceptionally well during both high-intensity activity and everyday wear.

This model is designed to disappear on the body — no distractions, no excess weight, just pure function.

Designed for comfort and freedom of movement

The classic tank silhouette allows full range of motion for shoulders and upper body. The fabric stretches naturally with movement while remaining stable and shape-retentive over time. Ideal for training, travel, or layered use.
