Outdoor brand COBMASTER is adding a new item to its lineup: the HUMMING PACK VEST, a vest-style pack that merges backpack storage capacity with the freedom of movement of a running vest. The product is scheduled to go on sale in mid-June 2026.

The HUMMING PACK VEST draws on COBMASTER's experience in bag design to create what the brand describes as a "wearable backpack." Smartphones, drinks, and mobile batteries can be stored in pockets positioned close to the body, allowing quick access without removing the pack — a practical feature during music festivals or outdoor leisure activities.


Product Features
Access Essentials Without Taking It Off
The vest section features 8 pockets that efficiently store smartphones, drinks, mobile batteries, and other everyday essentials. This layout supports smooth, uninterrupted movement at festivals or during outdoor activities.

Approximately 12L Storage Capacity
The back section provides around 12L of storage space. A bungee cord on the base allows towels and rain gear to be secured externally, making the vest suitable for day trips through festival use.

Designed for Active Movement
A mesh panel on the back provides high breathability, while side belts allow for a secure, adjustable fit. The vest can be worn comfortably during active pursuits such as running and cycling.
