Inov8 says: 

Carry everything you need for shorter training runs and races with the RACEPAC 4. Holding up to four litres of fluid, kit and nutrition, this pack is ideal for shorter trail races up to half marathon distance.

The RACEPAC 4 can comfortably fit two 500ml soft flasks in its front pockets, or a two-litre hydration reservoir in its main rear compartment (flasks and reservoir sold separately). This same rear compartment can hold kit and nutrition too, with or without a reservoir in there.

Keep your valuables and essential kit/fuel to hand with three quick-access pockets on the front of the vest (one of which is zipped). Thoughtfully designed, these pockets allow you to easily get to that gel, or pull your phone out for that summit selfie!

The pack’s breathable air -mesh inner works hard to wick away sweat, keeping you comfortable during your run. All of the main materials of the RACEPAC 4 contained recycled content.

The RACEPAC 4 comes in a single size, with side adjustment straps and a bungee chest strap allowing you to find that perfect, zero-bounce fit. There are also pole attachment straps on the front of the pack, for those hillier runs.

Our Verdict

The Inov8 Racepac 4 Running Vest is a well-designed and functional hydration pack tailored for shorter training runs and races. With a capacity of up to 4 litres, this vest offers ample space to carry fluids, nutrition, and essential gear. The front pockets accommodate two 500ml soft flasks, while the main rear compartment can fit a 2-litre hydration reservoir (sold separately), providing sufficient hydration.

One of the standout features of the Racepac 4 is its thoughtful design that prioritises comfort and convenience—the breathable air-mesh inner works to wick away sweat, keeping you cool and comfortable throughout your run. The three quick-access pockets on the front, including a zipped pocket with a bungee cord for keys and an emergency whistle, allow you to access your essentials easily.

Additionally, the front pole attachment straps make stowing and quickly accessing your poles convenient during technical or hilly runs. At 207g and made of recycled content, this vest balances lightweight performance and sustainability.
