• ------------------
• Material Differences (Ultra 200X and UltraGrid)
• Both materials are waterproof
• The Kakwa 55 backpack utilizes Ultra 200X and UltraGrid fabrics from Challenge Outdoor
• The fabric is partially (UltraGrid) or primarily (Ultra 200X) woven from Ultra-High-Molecular-Weight Polyethylene (UHMWPE) fibers, providing strength and abrasion resistance several times greater than traditional nylon backpack fabrics
• Ultra 200X fabric is laminated to a film using an eco-friendly adhesive to form a waterproof layer
• UltraGrid uses a polyurethane (PU) coating for waterproofing
• ------------------
• The Kakwa 55 is our high-end, ultralight multi-day backpack. Its design adheres to the primary principles of load-carrying and ergonomics, delivering exceptional functionality, comfort, and ease of use for an ultralight backpack
• Derived from Dan Durston's obsessive attention to detail and thousands of miles of backpacking experience, the Kakwa 55 boasts top-tier quality, load capacity, materials, and pocket design, all while weighing under 900g
• Super Fabric
• Ultra 200X is primarily woven from Ultra-High-Molecular-Weight Polyethylene (UHMWPE) fibers, offering strength and abrasion resistance multiple times higher than traditional nylon backpack fabrics. This fabric becomes waterproof after lamination. This backpack utilizes the brand-new "X" version, which adds a tougher inner film layer
• Hollow Aluminum Frame
• The inverted U-shaped frame provides both vertical and horizontal structure, while the hollow aluminum tubing makes it lighter than flat frames
• Load Lifters
• Load lifters are often omitted on lightweight backpacks, but they are a key component of the Kakwa's exceptional load-carrying capability
• Ergonomic Shoulder Straps
• The shoulder straps feature an ergonomic S-shape, which fits almost everyone better than straight straps
• Dual-Strap + Reverse-Pull Hip Belt
• The dual-strap hip belt wraps around your hips, while the 2:1 leverage and reverse-pull design make it easy to tighten
• Y-Top Strap
• The Y-top strap allows items like bear canisters and tents to be lashed securely to the top
• Attachments
• There are eight attachment points around the backpack, making it easy to attach various gear
• Hip Belt Pockets
• Dual hip belt pockets come standard and are sophisticatedly designed for easy one-handed operation
• Shoulder Strap Pockets
• Shoulder strap pockets come standard, providing convenient storage for phones, bear spray, sunglasses, and small water bottles
• QuickPocket
• The unique QuickPocket on the left side allows you to access larger items than before on the go, such as hats, gloves, and maps
• Hydration Compatible
• The hydration port makes it compatible with water bladders
• Durable Mesh
• The front pocket uses a durable knit mesh, creating volume through pleats (folds) rather than using less durable stretch mesh
