Fabric Systems
Built for Resistance. Engineered for Performance.
Every piece within the PREFRD performance line is built on a foundation - the Core Fabric System.
Each fabric was developed with a specific purpose: to support movement, regulate performance, and eliminate distraction under pressure. From ultra-lightweight output layers to structured training garments, every material serves a defined role within the athlete’s environment.
This system was created to perform when resistance is present - when fatigue sets in, when conditions shift, and when discipline becomes the deciding factor. Every fiber, every blend, and every construction choice exists to support the athlete through sustained effort and repeated use.
Nothing unnecessary. Nothing without purpose.
Endure to Evolve.
CoreLite™ Fabric System
Engineered for unrestricted performance. Built for relentless output.
CoreLite™ is a precision-engineered performance fabric developed to move without resistance and perform under pressure. Constructed from a technical Nylon, Spandex, and Polyester blend, it delivers the perfect balance of breathability, stretch, and durability - allowing you to train harder, longer, and without distraction.
Designed specifically for high-output training environments, CoreLite™ maintains a weightless feel while providing the structural integrity required for repeated wear. Its advanced moisture management system actively pulls heat and sweat away from the body, keeping you cool, dry, and fully focused through every phase of movement.
This is not just lightweight. This is controlled performance.
CoreLite™ Key Features
• Ultra-Lightweight Construction
Minimizes restriction and eliminates excess weight, allowing full freedom of movement in every direction.
• Advanced Breathability System
Promotes constant airflow to regulate body temperature during intense training and high-output sessions.
• Dynamic 4-Way Stretch Performance
Adapts to your movement naturally, maintaining comfort and mobility without losing shape.
• Moisture-Wicking Technology
Pulls sweat away from the skin to accelerate evaporation and maintain dryness.
• Precision Recovery Structure
Retains its original fit and form after repeated wear, training, and washing cycles.
• Soft Technical Hand Feel
Smooth against the skin while maintaining a durable, performance-ready exterior.

CoreGrid™ Fabric System
Engineered for regulation. Built to maintain readiness.
CoreGrid™ is a structured performance fabric designed to stabilize the athlete between phases of effort. Defined by its precision grid-knit construction, it creates controlled airflow channels while preserving the structural integrity required to maintain form, temperature, and composure.
Unlike lightweight output fabrics, CoreGrid™ is engineered to regulate rather than release. Its grid framework traps and releases heat strategically, preventing rapid temperature shifts while allowing excess heat to escape when needed. This creates a stable internal environment, allowing the athlete to remain prepared before, during, and after performance.
The fabric holds its structure without stiffness, moving naturally with the body while maintaining its engineered foundation. CoreGrid™ does not collapse under fatigue or lose its form through repeated use. It remains consistent, controlled, and dependable under sustained resistance.
This is not built for output. This is built for control.
CoreGrid™ Key Features
• Engineered Grid Regulation System
Grid-knit structure stabilizes temperature by balancing heat retention and release.
• Structural Performance Framework
Maintains garment integrity and form through repeated wear and movement.
• Thermal Stability Control
Prevents overheating and rapid cooling by regulating airflow precisely.
• Adaptive Layering Performance
Designed to function as a performance layer without restricting mobility.
• Durable Structural Integrity
Retains shape, structure, and performance over time.
• Balanced Performance Weight
Substantial enough to regulate temperature while remaining comfortable and mobile.

CoreTrain™ Fabric System
Engineered for durability. Built to endure repeated resistance.
CoreTrain™ is a structured performance fabric developed to withstand the demands of consistent training while maintaining unrestricted mobility. Built using a precision French terry construction, it delivers the durability required for repeated wear without sacrificing comfort, movement, or fit integrity.
Unlike lightweight output fabrics, CoreTrain™ is engineered to provide a stable performance foundation. Its structured composition allows the garment to hold its form through dynamic movement, maintaining a clean silhouette while adapting naturally to the athlete’s body.
The interior terry knit promotes breathability and temperature balance, preventing overheating while providing a substantial, controlled feel. This allows CoreTrain™ to perform in training environments while remaining durable enough to endure the stress of daily wear.
This is not built for temporary performance. This is built to last through it.
CoreTrain™ Key Features
• Structured French Terry Framework
Engineered to provide durability and stability while maintaining natural flexibility.
• Performance-Driven Mobility
Moves with the body without restriction, allowing full range of motion during training.
• Shape Retention System
Maintains original form and fit through repeated wear, washing, and performance cycles.
• Durable Performance Construction
Built to withstand consistent stress without breakdown, deformation, or loss of integrity.
• Breathable Interior Terry Knit
Promotes airflow and temperature balance while maintaining structural stability.
• Precision Fit Integrity
Designed to maintain its intended silhouette while adapting to movement.

CoreFlow™ Fabric System
Engineered for natural movement. Built to perform without disruption.
CoreFlow™ is a performance-engineered cotton stretch fabric designed to deliver unrestricted mobility while maintaining a natural, grounded feel. Constructed from a precision 95% Cotton and 5% Spandex blend, it combines the softness of premium cotton with the adaptive stretch required for sustained movement.
Unlike purely synthetic performance fabrics, CoreFlow™ was developed to create a more natural performance environment — allowing the athlete to move freely while maintaining comfort, breathability, and structural integrity. Its cotton foundation provides a soft, controlled hand feel, while the integrated stretch fibers ensure the fabric adapts to motion without losing its form.
CoreFlow™ balances comfort and performance, allowing it to function seamlessly in both training environments and everyday wear. It maintains its shape, softness, and structural stability through repeated use, ensuring consistent performance over time.
This is not built to feel synthetic. This is built to move naturally under resistance.
CoreFlow™ Key Features
• Premium Cotton Stretch Construction
Combines the natural softness of cotton with engineered stretch for unrestricted mobility.
