The 9th collaboration with the fashion brand “White Mountaineering” is here.
Designed for commuting, gym visits, and daily mobility, it uses two water-resistant materials durable enough for outdoor use.
By combining fabrics with different textures, it achieves a rich and varied look even in an all-black color scheme.
From weekdays to weekends. From the city to the suburbs. This collaboration between BRIEFING and White Mountaineering bridges multiple scenes, offering both high functionality and sophisticated design.
【Specifications】
Interior: Medium mesh pocket × 1
Exterior:
Front: Large pocket × 1 (buckle closure, includes small zip pocket × 1 inside)
Large zip pocket × 1
Side: Small pocket × 2
Back: PC sleeve × 1 (with cushioning, fits a laptop up to approx. 16 inches)
【Recommended Points】
- Contrasting textures -
・Base fabric is polyurethane-coated CORDURA® with partial use of water-repellent nylon twill on the left front panel and sections of the shoulder straps.
The CORDURA® base offers a water resistance level of 1,500 mm, withstanding heavy rain — perfect for city walks as well as outdoor and leisure activities.
・The matte, crisp CORDURA® fabric contrasts with the glossy nylon twill, adding depth and presence to the all-black color scheme.
- Special collaboration details -
・The “BLK” line concept phrase “BLACK LAYER KNOWLEDGE” is expressed in jacquard tape, featured as a design accent on the front.
・Signature collaboration name tag incorporating both brands’ logos, unified in black to match the bag body.
