Spigen Running Hydration Vest – Dynamic Shield A721
Guaranteed Safe Checkout
Spigen Dynamic Shield A721 is a running hydration vest with an included 500 mL flask and a multi-pocket layout for a phone, fuel and small essentials. The Active Black design adds rear storage and adjustable chest and waist fastenings. Choose the size that matches your chest measurement for a closer, more stable fit.
Key Features
- 500 mL flask included: A dedicated front pocket keeps the supplied flask within reach.
- 3 L rear compartment: Carry a light layer or use a compatible hydration bladder up to 2 L, sold separately.
- Adjustable body fit: Two chest buckles and two waist adjustment straps help position the load against the body.
- Organised pockets: Front and side storage separates a phone, energy gels, keys and other small items.
- Outdoor details: Trekking-pole holders, reflective accents and a built-in whistle support the running setup.
Organised hydration and storage for longer outings
The A721 has a different pocket and hydration layout from the A720. Use the front storage for items you need frequently and the rear compartment for a light layer or compatible bladder. Dual compression cords help secure the rear load. Check the closures and adjust the load distribution before starting your route.
Choose M–L for a chest circumference of approximately 77–95 cm, or L–XL for approximately 90–110 cm. Removable chest buckles allow their position to be adjusted. Measure over the clothing you intend to wear and leave enough room to breathe and move comfortably. Tightening straps cannot make the wrong size fit every body shape.
Zoned mesh supports ventilation across the back, chest and front storage areas. The vest weighs approximately 172 g in M–L and 186 g in L–XL before adding your contents. These weights do not represent the total carried load. Clean and dry the flask and vest according to their care instructions; reflective details and the whistle complement, rather than replace, suitable route planning and safety equipment.
Compatibility
- M–L: chest approximately 77–95 cm / 30–37 inches.
- L–XL: chest approximately 90–110 cm / 36–43 inches.
- Rear compartment supports a compatible hydration bladder up to 2 L; bladder not included.
Package Includes
- 1 × Spigen Dynamic Shield A721 vest in the selected size.
- 1 × 500 mL flask.
- Phone, hydration bladder, trekking poles and other demonstration items are not included.
