Although, this is the first time SOPHNET. and Briefing are working together, it is safe to bet that it won't be their last. These N-1 Tote Bags are the epitome of high quality American manufacturing, utilizing proven military specification parts. Exterior of the bags are made from highly durable 500 denier Cordura nylon materials. This tote bag is designed to be a reversible piece, with acrylic boa material lining the inside. Tow colorways are available in black and khaki, and these are scheduled to drop this Sunday, December 23, at SOPHNET. stores and dealers in Japan, as well as through Isetan Men's in Shinjuku.
