Any runner who has struggled with a hand-held bottle or worn a bulky pack that throws off their stride knows the issue: staying hydrated on a long run or trail shouldn't slow you down or weigh you down. This 5L running vest hugs the body, spreads weight evenly, and keeps your essentials within reach without bouncing or restricting movement — so you can run further and more comfortably.

Why It Stands Out

✓ 5L capacity — enough space for a hydration bladder, snacks, phone, keys, and small trail essentials without the bulk of a full backpack.

✓ Compatible with hydration systems — accommodates a 2L hydration bladder (included with the Camelbak variant); the water bag outlet and kettle position allow easy drinking on the move.

✓ Mesh strap system — padded, adjustable shoulder straps with mesh panels promote airflow and conform to the body for a secure, comfortable fit on long runs.

✓ Multi-compartment design — front strap pockets provide quick access to snacks, a phone, or gels without stopping or taking off the vest.
✓ Reflective strips — built-in reflective elements keep you visible in low-light conditions during early morning or evening runs.

✓ Lightweight at 250 g — ultra-light construction means the vest is barely noticeable during a run, even over longer distances.

✓ Unisex fit — adjustable waist strap fits a waist circumference of 66 to 144 cm, suiting a wide range of body types.

Where It Fits Best

On trail runs and ultramarathons, the vest keeps hydration and nutrition within reach without breaking stride. For road runners training over longer distances, it removes the need for hand-held bottles while carrying more than a basic arm band allows. Hikers who prefer a fast-and-light approach benefit from the 5L capacity without the structure of a traditional hiking pack. Cyclists use it on longer rides where jersey pockets aren't sufficient. It also works well for outdoor races, cycling events, mountaineering approaches, and multi-sport events where weight and freedom of movement are priorities.

How the Vest and Hydration System Work

The vest body is made from lightweight polyester with a hexagonal mesh pattern on the shoulder straps for ventilation. The main compartment holds a 2L hydration bladder (included with the Camelbak variant); the water bag outlet at the shoulder directs the drinking tube for easy access while running. A separate kettle pocket on the front strap holds a soft flask or small bottle upright. The waist strap adjusts through side buckles to fine-tune the fit and minimise bounce. The 2L bladder included with the Camelbak variant is TPU construction, 100% BPA and PVC free, with a silicone nozzle rated for water temperatures of 0–40°C.

Comparison Table

Setup and Fitting

Put the vest on and tighten the shoulder straps until the pack sits firmly against your back without sagging. Adjust the waist strap using the side buckles to your waist circumference (66–144 cm) to minimise bounce. If using the hydration bladder, slide it into the main compartment and thread the drinking tube through the shoulder strap outlet. Fill the bladder with water at 0–40°C. Load the front strap pockets with gels, a phone, or small items for quick access. Make sure all buckles are fastened before setting off.

Cleaning and Care

Hand wash the vest in cool water with a mild detergent and hang to air dry. Do not machine wash, tumble dry, or iron. Empty and rinse the hydration bladder after every use and let it dry fully before storing to prevent mould. The bladder can be rinsed with clean water; avoid using detergents inside the bladder as they may affect the taste. Store the vest uncompressed in a dry location.
