【Design】
This backpack adopts a roll-top structure that allows flexible capacity adjustment according to the amount of luggage. This structure emphasizes capacity variability rather than waterproofing, and its greatest feature is the side zipper that allows direct access to PCs and the like, which is rare in roll-top bags. This enables smooth in and out access without opening the main compartment, dramatically improving convenience for everyday use. The interior has a minimal structure with minimal partitions, allowing you to pack your belongings freely and without waste. Furthermore, the front open pocket and the bottle pockets on both sides feature gussets that vary according to storage volume, creating a meticulous design that fits every scene from urban use to travel.

【Material Texture】
The body material uses the special fabric "UltraWeave," which boasts astonishing strength while being ultra-lightweight. This polyethylene fiber has overwhelming strength, being 15 times stronger than steel and over 40% stronger than aramid fiber by weight comparison, and it is 20% lighter and four times stronger than other high molecular weight polyethylene materials. It also offers excellent durability against water, UV rays, and chemicals, and because of its high reliability, it is also adopted as material for bulletproof vests. It is truly a next-generation functional material that combines lightweight and robustness―two contradictory elements―at an extremely high level.

■ Usage season guideline
Due to the nature of the material, it can be used all year round regardless of season. The ultra-light and tough material allows you to use it confidently in active scenes without worrying about the weather.
