Key Details

|---|---|
| Vest | Black running vest made from nylon mesh, weighing around 250 g. |
| Storage | One 5 L main rear compartment and multiple pockets with zips and fasteners. The 5 L figure applies to the main compartment, not necessarily the vest’s total storage. |
| Included hydration | One 0.5 L collapsible soft bottle. |
| Bladder provision | Integrated sleeve and hanging hook; stated to accommodate bladders up to 3 L. The bladder is not included, and capacity alone does not establish fit or connection compatibility. |

| Fit adjustment | Adjustable chest and side straps; no wearer measurement range is specified. |
What to Compare Before Buying
Check whether the 5 L rear compartment and smaller pockets suit the items you intend to carry. The stated 5 L applies to the main compartment, not necessarily the vest’s total storage capacity.
If choosing a hydration bladder, check its dimensions and connections against the vest and your preferred drinking setup. The stated maximum is 3 L, but capacity alone does not establish that every bladder will fit or connect.
The vest has reflective strips and LED lights, but no visibility distance or light performance is specified. Check the lights’ power source and how they attach, and do not treat these features as a guarantee of visibility in every condition.
Compatibility, Size and Fit
Adjust the chest and side straps to check the vest sits as you prefer when loaded. No measurement range is given, so do not assume the adjustable straps will provide a suitable fit for every wearer. Check how the filled bottle or a bladder affects the fit and access to pockets.
What Is Included
The bundle is described as including the vest, one 0.5 L soft bottle and a pair of LED lights. A hydration bladder is not included. No further contents are specified.
Prepare a Run Load-Out
Before heading out, lay out what you plan to carry and assign it to the rear compartment and smaller pockets. Check that items you may need during a run are reachable with the vest adjusted, and that the soft bottle is easy to remove and replace. If using a bladder instead, confirm its fit and drinking connection beforehand. Check how the supplied lights are powered and fitted, and confirm they are working before setting out.
Before You Decide
Check the adjustable fit, whether the 5 L main compartment meets your storage needs, and whether you plan to use the included 0.5 L bottle or source a compatible bladder separately. Also check the LED lights’ power and attachment details.
