This is a Japan-exclusive model, based on the 2016 version with increased strength, and with improved storage capacity. This 20L model was released in the fall of 2017 and quickly sold out. While maintaining the strength of the pack itself, we pursued the ultimate in weight reduction, using ultra-lightweight and durable 60d nylon for the material. Items can be easily accessed thanks to the waterproof center zipper that opens widely vertically, allowing instant access to items inside the pack. This ease of use has gained tremendous support from athletes in races like the TJAR. From there, we actively incorporated feedback from Japanese mountain racers to complete this Laser20 Pro. A lightweight and breathable backpack featuring zippered pockets and adjustable straps. - Color: Black - Design: Zippered pockets, mesh material - Features: Lightweight, breathable straps - Functions: Multi-functional pockets, adjustable straps Thank you for viewing.
