BUILT TO BREATHE. ENGINEERED TO MOVE.

The FERAL Core Performance Tee is a lightweight endurance top engineered around airflow, moisture movement, anatomical fit, and unrestricted upper-body motion.

Strategic ventilation zones, low-profile seams, four-way stretch performance fabric, and movement-focused patterning create a technical running layer designed for sustained output across road, trail, and race conditions.

A performance tee should disappear during movement.

The Core Performance Tee was built around that objective.

FERAL developed the U-CPT as the lightweight upper-body layer within the broader endurance system, balancing airflow, sweat transport, fit stability, shoulder mobility, and repetitive-motion comfort.

The body uses a lightweight stretch performance fabric developed to move naturally through running mechanics without creating unnecessary fabric drag.

Rather than treating ventilation as a surface graphic, the Mapped Ventilation System™ places higher-airflow zones where heat and moisture accumulation are most likely. Primary ventilation areas include the upper back and selected torso regions, with the exact construction method subject to final production testing.

The upper-body pattern is shaped around the mechanics of arm drive. Raglan or anatomically curved shoulder construction reduces the dependence on a conventional shoulder seam and allows the sleeve and torso to move as one connected system.

Across the garment, seams remain low profile and strategically routed away from high-friction regions.

The Core Performance Tee is intentionally visually restrained. Subtle structural lines, tonal material transitions, and ventilation geometry communicate the engineering without turning the shirt into a graphic-heavy garment.

It is designed to work independently or as part of the FERAL system.

Lightweight where possible. Structured where necessary.

ENGINEERED FEATURES

MAPPED VENTILATION SYSTEM™

Strategically positioned ventilation zones are integrated into high-heat regions including the upper back, center back, upper chest, side torso, and underarm transition zones. The final method may use engineered knit, mesh, perforation, or laser-cut construction depending on production validation.

ANATOMICAL 3D PATTERNING

The garment is shaped around upper-body movement rather than constructed as a flat generic T-shirt block. Patterning supports arm drive, shoulder movement, torso rotation, running posture, and repetitive endurance motion.

MOBILITY-FOCUSED SHOULDER ARCHITECTURE

Raglan, hybrid raglan, or anatomically curved shoulder geometry reduces bulky seam stacks directly across high-motion shoulder zones.

RAPID-DRY FABRIC SYSTEM

The primary textile prioritizes moisture transport, rapid drying, lightweight hand feel, breathability, four-way movement, and wet-state comfort.

LOW-PROFILE SEAM CONSTRUCTION

Flatlock or similarly low-profile seam architecture is used where appropriate. Repetitive-motion comfort is prioritized at the underarm, side body, shoulder, neck, and sleeve interface.

LIGHTWEIGHT PERFORMANCE FIT

The silhouette sits close enough to reduce excess fabric movement without becoming compression tight. The tee reads as a technical endurance garment.

TONAL ENGINEERING LANGUAGE

Subtle structural paneling and material transitions visually connect the tee to the broader FERAL system. The visual language remains lighter than the compression products.

MATERIAL ARCHITECTURE

Primary Body

Lightweight nylon/elastane or polyester/elastane performance stretch textile. Designed for lightweight feel, four-way movement, moisture transport, rapid drying, breathability, soft skin contact, and dimensional recovery.

Ventilation Zones

Engineered mesh, perforated stretch material, laser-cut construction, or high-airflow knit. Final method remains subject to prototype and wash testing.

Shoulder / Mobility Zones

Stretch architecture designed to support unrestricted arm drive and shoulder movement.

Seam Construction

Flatlock or other low-profile performance seam construction where appropriate.

Branding

Tonal graphite or metallic-silver FERAL branding.

Final material specifications remain subject to sourcing, prototype development, wash testing, wear trials, and production validation.

FIT

• Fit: Performance / Athletic

• Gender: Unisex

• Sleeve: Short Sleeve

• Sizes: XS / S / M / L / XL / XXL

Designed to follow the body without creating a compression fit. The silhouette provides enough ease for unrestricted movement while remaining close enough to reduce unnecessary fabric movement during running.

Final consumer measurements and size guidance will be published following grading and wear testing.

COLOR

Carbon Black

A matte Carbon Black performance textile with tonal graphite panel transitions and restrained metallic-silver FERAL branding. Ventilation zones remain black or graphite.

BUILT AS A SYSTEM

The Core Performance Tee is the lightweight upper-body layer of the FERAL endurance system.

Ventilation manages heat. Anatomical patterning preserves movement. Low-profile seams reduce unnecessary bulk. The shoulder architecture follows arm drive. The lightweight chassis layers cleanly with the rest of the system.
