CRAFT IN EVERY DETAIL
More than fabric and thread, these sweats are the result of deliberate choices. Odorblock™ keeps them fresh, and the pre-shrinking process preserves their fit and shape over time. Each treatment is applied with purpose, extending the life of the garment and ensuring they endure season after season.

ATHLETE-LED DESIGN
The Heavyweight Core Sweatpant was shaped by the people who live in them — athletes, adventurers, and everyday grinders. Their input refined the fabric, the fit, the pocketing, and the construction, creating a piece that honors tradition while standing up to modern demands. Every stitch tells the story of refinement, durability, and purpose.
