You train heavier and run safer with a 5–10 kg adjustable vest engineered for balanced muscle loading and all‑day comfort.
- Fill the internal chamber with dense iron sand until you reach your preferred 5–10 kg load, then fasten the back and chest buckles to eliminate shifting during burpees and trail runs.
- Direct resistance evenly along your spine with true 50/50 front‑to‑back distribution that preserves natural posture when you push past your limits.
- Carry your phone, keys, and energy gels in the deep rear sleeve, shoulder arm pouch, and elastic mesh front panel so nothing breaks your rhythm.
- You stay dry and highly visible wearing moisture‑wicking Lycra and SBR backing with thick shoulder pads that disperse strain, while reflective trim improves visibility during dawn sessions.
