Product Description
Crux RK30
■Manufacturer's Description
A lightweight, fully waterproof alpine backpack that has continued to evolve since CRUX's founding
RK series [ロールトップタイプ]
The roll-top style without a top lid allows quick access to the main compartment, with a large opening that makes it easy to see inside and retrieve what you need.
Additionally, the lightweight nature due to the simple structure is a major appeal.
"Two Assurances"
・Fully Waterproof
Being fully waterproof provides peace of mind against water during rainy mountain trips, stream climbing, alpine climbing, etc. The roll-top part is made of flexible material, enhancing airtightness and achieving full waterproofness.
・High Durability
Made from durable Kevlar material, it offers reassurance against damage on rocky areas, walls, streams, ice core routes, and itineraries.
[防水性] The Kevlar is coated on the inside with a water pressure resistance of 10,000mm. Furthermore, the fabric seams are welded to prevent water intrusion.
[耐久性] The main body fabric Kevlar is a material that withstands strong contact or pressure from rocks, ice, branches, route structures, and gear such as axes and ski edges.
[シンプル性] By designing the structure simply, it minimizes exposure to damage or troubles during routes, multi-day mountain trips, and long-term trips.
[リペア] Spare parts are prepared for many components, allowing for replacement. Also, repairs are performed as much as possible at the factory where it was produced, establishing a system for long-term use of a single backpack.
