A backpack designed with expandability in mind, based on the concept of being able to attach gear externally.
Inside, it has a total of five compartments: a main pocket, a PC sleeve, an internal small-item pocket, and two front compression pockets. The PC sleeve fits up to 15 inches.
Drink holders are placed on both sides.
Optional waist bags and hip belts can be attached, allowing for a variety of uses depending on the purpose.
The upper and lower buckles allow external attachment of items such as a dry sack or sleeping mat.
The waist tape, which functions as a simple waist belt when used on its own, also serves as a connection point when attaching the optional hip belt.
Uses Challenge Outdoor’s UltraWeave. Despite being ultra-lightweight, it is made from extremely tough polyethylene fiber, offering 15 times the strength of steel and more than 40% greater strength than aramid fiber on a weight basis. Compared to other ultra-high-molecular-weight polyethylene materials, it is 20% lighter and boasts four times the strength.
It uses a special material that is highly resistant to water, UV rays, and chemicals, and is also used in bulletproof vests.
Two types of fabric are used in different areas depending on the detail: the front compression section uses a fabric with excellent waterproofness and tear strength, while the body uses a fabric with excellent abrasion resistance.
Outer fabric: 100% Polyester / Contrast fabric: 67% Polyethylene, 33% Polyester Capacity: 30L.
