New British brand · Performance hydration
The hydration vest built for serious runners.
1.5L bladder. 340g total. Zero bounce, whatever the distance.
01 · Hydration
Drink without breaking your stride.
A 1.5L bladder with secure hose routing keeps water within reach for the full run. No stopping. No fumbling. No pace lost mid-stride because you couldn't find the bite valve.
Tested on long training loops, road and off-road, and everything a serious runner's week throws at it.
02 · Fit & stability
Zero bounce. Even full.
Adjustable side straps and balanced weight distribution keep the vest locked in place — whether you're carrying a full bladder, a layer, your phone, gels and a whistle. No ride-up. No sway, whatever the pace.
The waterproof front pocket keeps your phone protected and visible through wind, rain and sweat — touchscreen works right through the seal. Shoulder storage keeps smaller essentials — gels, keys, a gel wrapper you'll pack out — exactly where you need them.
Inside the vest
Built to the same spec as vests twice the price.
340 grams. 1.5-litre bladder included. Six compartments. Waterproof phone pocket. 2 LED safety lights. Multi-tool clip. Reflective trim. We left the brand markup at the door.

1.5L bladder compartment with secure hose routing. Reflective trim across chest and back. 2 clip-on LED safety lights for dawn starts and dusk finishes.
03 · Run-ready
Prepared for the unexpected.
Integrated safety whistle. Two clip-on LED lights for low-visibility starts. A multi-tool clip with compass, carabiner, bottle opener and fire striker. Reflective trim. Built for long runs, early starts, and the reality of weather turning on you a few kilometres from home.
Serious runners prepare for every condition. This vest assumes you do too.
