Ultralight and fast, highly weather resistant, alpine strong, and a sterling example of refined, use specific Arc’teryx design, the Alpha FL 30 Backpack is for built for climbers. An intense focus on the realities of moving fast in alpine environments led to this versatile, streamlined pack that combines leading edge, Arc'teryx developed fabric technologies, performance focused design and a confident simplicity. Working together, the highly durable, weather impermeable N400-AC² fabric, taped seams and RollTop™ closure combine to shut out the elements and protect the pack’s contents. With no extraneous materials or aspects, the Alpha FL 30 sheds grams but does not sacrifice necessary features. An external bungee attachment secures tools, crampons, belay parka, helmet or sleeping pad. A simple strap at the top secures a rope, and the unique laminated shoulder strap construction delivers a comfortable carry without unnecessary weight. An external security pocket stores small essentials.
