ALTUS Fire Backpack 18L: Your Agile Partner for Vertical Pursuits

Engineered for the modern climber and avid hiker, the ALTUS Fire Backpack 18L is a masterpiece of lightweight efficiency and streamlined design. This frameless 18-liter pack is purpose-built to move with you, providing unrestricted freedom on multi-pitch sport routes, classic climbs, and challenging hiking trails. Designed for both men and women, its compact, adult-sized form factor in the 11-20 L category ensures it never gets in the way, allowing you to focus purely on the ascent and the adventure ahead. Its frameless construction provides maximum flexibility and a close-to-body fit, essential for dynamic movements.

Experience unparalleled convenience with the Fire´s innovative access systems. The top quick release and an opposing opening strap allow for effortless entry into the main compartment, a crucial advantage when you´re on a small ledge or need gear in a hurry. Externally, the adjustable strap for a helmet and rope keeper lets you securely carry your most critical equipment, maximizing internal space and keeping you organized from the car to the crag. Two side compression straps pull the load tight against your back, ensuring a stable, no-bounce carry that is essential for maintaining balance on delicate moves.

Stay organized and prepared with thoughtfully placed storage. Three zipped pockets secure your valuables, while an external quick-access mesh pocket is perfect for stashing a water bottle, snacks, or a guidebook. For long days, the dedicated compartment for a hydration pack allows for easy, on-the-move hydration. The fit is fully customizable thanks to adjustable chest and waist straps, including a chest buckle with an integrated safety whistle for an added layer of security. The waist strap is also retractable, allowing it to be tucked away neatly when wearing a climbing harness, demonstrating its thoughtful, activity-specific design.

I'm super happy with it. It's very light and comfortable despite not having a padded waist. Perfect for climbing, as it opens from the top unlike other backpacks. The elastic front fabric is super useful for storing anything while you're going from one place to another. I'm really happy with it.
