Ventilated Reflective Running Hydration Vest

At just 280 g and measuring 30 x 20 x 8 cm, this hydration vest uses lightweight neoprene with triple-sized ventilation holes and a ventilated mesh back panel to optimise breathability and heat dissipation. Adjustable shoulder straps ensure a secure, gender-inclusive fit. Storage configuration includes: a main internal compartment (bladder-compatible), right-side external pocket for small water bottles, left-side smartphone pocket (designed for devices up to 6.7 inches), and a large central pocket secured by cross elastic cord. Front and back reflective trim enhances visibility in low-light conditions, and included strap clips prevent dangling webbing. The vest’s engineering focuses on kinetic efficiency: the low centre of gravity minimises inertia during arm swing, the contoured neckline avoids collarbone pressure, and the flat-locked seams eliminate friction hotspots. The neoprene/mesh hybrid fabric manages moisture both internally (wicking) and externally (evaporative cooling), while maintaining structural resilience against repeated folding and packing. Tested across London parkruns, Peak District trails and Thames Cycle Superhighway commutes, it delivers consistent performance in variable urban and rural environments. It bridges the gap between specialist race vests and general-purpose hiking packs — offering hydration readiness, tech accessibility and safety compliance in one cohesive, field-proven design.
