T2 - Ultra 5

Tabisuke Tabizo T2 Ultra 5

The T2 Ultra 5 is a 5-liter running vest engineered for trail running and ultramarathons, offering a compact, high-performance carry solution for runners who prioritize efficiency and freedom of movement over extended efforts. Built around Tabisuke Tabizo's proprietary T2 High Mount Fit™ 2.0 technology, it positions the load high on the thorax to minimize bounce while preserving natural pelvic movement, making it equally suited to fast efforts and long technical days on trail.

The vest is constructed from a high-strength, 4-way stretch lightweight nylon that balances durability with unrestricted mobility across all planes of movement. Nylon mesh panels are integrated throughout critical contact zones to promote active ventilation, managing heat and moisture during sustained output. The overall architecture keeps weight distributed across the upper back and trapezius area, reducing cumulative fatigue and preventing the downward load shift that compromises posture and efficiency on long climbs and descents.

Key Features

• T2 High Mount Fit™ 2.0
  A proprietary load-positioning system that compresses storage upward toward the thorax, minimizing bounce and enhancing fit around the trapezius muscles to support sustained performance over long durations.
• BFS (Back Fitting System)
  A one-hand adjustable fitting mechanism that enables precise fit calibration while running, allowing the vest to adapt to changing terrain and fatigue without requiring a stop.
• Reverse-Slant Main Storage
  The main compartment features a reverse-slant orientation that prevents gear from sinking downward during movement, maintaining a stable high-mounted load position and reducing bounce throughout the effort.
• High Breathability Construction
  The primary fabric combines high-strength 4-way stretch nylon with strategically placed nylon mesh panels across key ventilation zones, promoting airflow and moisture management during high-intensity efforts.
• Flask Pockets with Compression Cord
  Front flask pockets are equipped with a cord-based compression system that actively reduces bounce and prevents flasks from drooping during movement; each pocket also includes an internal trash pocket for nutrition waste management on course.
