■ Design
This pack vest is based on archive items owned by Mr. Kobayashi, the designer of MOUNTAIN RESEARCH. It features a unique 3-way design where the vest and backpack are linked, and can be used independently by unbuckling them. Available in two colors: black and burgundy.

■Details
Vest: Equipped with a total of 12 pockets: 10 on the front and 2 on the back. The square flap pockets have hook-and-loop fasteners to prevent items from falling out. Two D-rings are located on the chest. It also features a snap-button fastener that allows for ventilation even when the front zipper is open.

Backpack: Features a classic teardrop shape. The gusset widens from top to bottom, stabilizing the center of gravity when carrying items and supporting a comfortable carrying experience. The main body is fitted with a leather ice axe holder in the shape of the MOUNTAIN RESEARCH 's iconic "Mountain A" mark, specially made for this collaboration.

■Size
The vest portion is available in one size (free size) with ample room. The harness's webbing belts allow for adjustable fit to suit your body type and the volume of your inner layers. The backpack portion has sufficient capacity for everyday use.

■ Material
The vest's outer shell and the backpack's main body are made of tough nylon fabric with the stiffness characteristic of outdoor gear. The vest's lining uses a soft polyester mesh fabric that prioritizes breathability and prevents sticking to the skin, enhancing comfort when worn.
