BLK White Mountaineering®︎ 3WAY DUFFLE

The 11th collaboration with White Mountaineering introduces a refined collection designed for both outdoor functionality and urban sophistication.
Combining eco leather and nylon selected exclusively for this collaboration, the material contrast adds depth to the clean silhouette while maintaining durability suited for active environments.

Inspired by White Mountaineering’s SS26 theme “Evolution theory,” the design balances toughness for outdoor fields with a polished aesthetic that blends naturally into city life.

Black hardware throughout the bag enhances a calm and modern presence while reinforcing functional performance.
A jacquard tape featuring the BLK concept phrase “BLACK LAYER KNOWLEDGE” is placed on the front as a subtle design accent.

The collaboration is completed with a dual name tag representing both brands. Finished in deep black, it quietly reflects the identity of BRIEFING and White Mountaineering while maintaining an understated and intelligent look.

This piece expresses the evolution of function and fashion through White Mountaineering’s distinctive design philosophy.
