Limited first production run · Launching this month · Shipped by Amazon UK
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 at the top of a climb because you couldn't find the bite valve.
Tested on long Peak District loops, South Downs trails, and everything a British trail weekend throws at it.
02 · Fit & stability
Zero bounce. Even full.
Dual chest 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 on descents. No sway on flats.
Front soft-stretch pockets hold your phone where you can see it. 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 litres. Seven pockets. Safety whistle. Reflective trim. We left the brand markup at the door.
Front
Soft-stretch bottle/phone pockets, bite-valve routing, dual adjustable chest straps, safety whistle.
Back
1.5L bladder sleeve, layer storage for a shell or mid-layer, reflective trim for low-light trails.
03 · Trail-ready
Prepared for the unexpected.
Integrated safety whistle. Reflective trim for dawn and dusk starts. Built for remote trails, exposed ridgelines, and the reality of British weather turning on you three kilometres from the car.
Serious trail runners prepare for every condition. This vest assumes you do too.
