5L Hydration Running Vest Backpack - Lightweight Reflective Trail Hiking Pack, Black
Return & Refund Policy

5L Hydration Running Vest Backpack - Lightweight Reflective Trail Hiking Pack
There is a moment on every long run where the pack you chose either disappears or ruins the day. This 5-litre hydration running vest is built to disappear. It hugs the torso like a second layer rather than swinging off your shoulders, so the rhythm you worked hard to find stays unbroken from the first kilometre to the last. Air-padded mesh shoulder panels breathe against the skin, the X-buckle chest straps pull the load in tight, and twin stretch pockets keep bottles exactly where your hands already expect to find them. Pull it on for a dawn trail loop, a half marathon, a cycling commute or a day hike, and it simply gets on with the job.
Finished in matte black with bright reflective panels and a bold JUST RUN print, it is made from lightweight, breathable polyester fibre that shrugs off trail dust and sweat. At only 280 g empty, it carries a phone, keys, gels, a light shell and your hydration without ever feeling like cargo.

Frequently Asked Questions
Does this vest include a water bladder?
No. This version is supplied as the black vest without a water bag. The twin front pockets hold soft flasks or bottles, and the pack is routed for a hydration tube if you add your own reservoir.
Will it bounce while I run?
The two X-buckle sternum straps adjust independently and cinch the vest against the torso, which is what stops the bounce. Tighten the upper strap first, then the lower one.
Is it suitable for both men and women?
Yes. It is a unisex design in one adjustable size covering an underarm circumference of 79-119 cm (31-47 in).
Is it safe for running at night?
Reflective strips run across the chest, shoulders and back so headlights pick you up in low light. It is a visibility aid, not a substitute for a head torch on unlit trails.
How long does delivery take to Canada and the USA?
Free shipping on orders over $25 to Canada & USA - delivered in 6-12 business days, with expedited delivery in 5-9 business days.
