01BACKPACKS
Breathable stability for the long run
The vest sits close to the body, its light grey fabric blending into the early morning mist or the dusty trail. It is designed to disappear against the skin, allowing the athlete to move without distraction.
This hydration pack suits runners, cyclists and hikers who need secure storage for essentials. The adjustable chest system keeps everything in place, whether you are sprinting or cruising.


02MATERIALS
Mesh that breathes with your effort
The rear panel uses a 3D polyester mesh structure, engineered to promote airflow across the back. This prevents the overheating common in solid-backed packs, keeping the wearer cool during sustained exertion. The material choice prioritizes ventilation over bulk, ensuring comfort even in humid conditions.

04FIT
Stability through adjustable tension
An adjustable chest system allows precise control over position and length, preventing bounce during high-impact activities. Reinforced sewing provides load-bearing strength, while flannel edging along the shoulder straps offers a soft, anti-chafe barrier against the skin. The fit remains secure regardless of pace.
05DETAILS
Visibility and safety features
Reflective webbing runs across the light grey exterior, enhancing visibility during night sports. An attached orange emergency whistle serves as a practical safety tool for outdoor excursions. A night warning strip further aids visibility, making this vest suitable for both day trails and evening commutes.
