T2 - Ultra 5

Tabisuke Tabizo T2 Ultra 5

The T2 Ultra 5 is a 5-liter running vest engineered for trail running and ultramarathons, built to offer the essential carrying capacity of a compact vest without compromising on stability or freedom of movement. It integrates Tabisuke Tabizo's proprietary T2 High Mount Fit™ 2.0 technology, positioning the load high on the thorax to minimize bounce while allowing natural, unrestricted pelvic movement throughout extended efforts.

The vest's construction distributes weight across the upper back and trapezius region, reducing fatigue during sustained efforts on technical terrain. The main fabric is a high-strength, 4-way stretch lightweight nylon that balances structural integrity with full freedom of movement, while nylon mesh panels are placed strategically across key contact zones to maximize ventilation and prevent heat buildup. A cord-based compression system stabilizes both the main storage and front flask pockets with a single pull, keeping the load secure and centered regardless of terrain.

Key Features

• T2 High Mount Fit™ 2.0
  High-mounted load structure that compresses storage toward the thorax, minimizing bounce and enhancing fit around the trapezius muscles to support sustained performance over long durations.
• BFS (Back Fitting System)
  One-hand adjustable fitting mechanism that enables precise fit adjustments while running, allowing the vest to adapt to shifting terrain and fatigue without requiring a stop.
• Reverse-Slant Main Storage
  The main compartment features a reverse-slant design that prevents gear from sinking downward, maintaining a stable high-mounted load and reducing bounce during movement.
• High Breathability Construction
  The primary fabric is a high-strength, 4-way stretch lightweight nylon offering both durability and unrestricted movement, complemented by strategically placed nylon mesh panels that enhance airflow across key contact areas.
• Flask Pockets with Compression Cord
  Front flask pockets are equipped with a cord-based compression system that reduces bounce and prevents flasks from drooping during running. Each pocket also includes an internal pocket for storing small waste items on the trail.
