The Ariel has become almost the benchmark for backpacks over the years. It is comfortable to carry and a popular choice for hiking and trekking! Ospreys carry system offers the right balance of flexibility while still allowing the load to be effectively transferred to the hip belt. The mens equivalent is the Aether, which features a carry system optimized for men and different color options. The lid of the backpack can be detached and used as a small daypack, perfect for short excursions like climbing to the top of a mountain near camp. The main compartment can be accessed from the top, through a front panel zipper, or via the sleeping bag compartment zipper. Extended Fit: longer hip belt (maxing out at 178 cm) and shoulder straps than in the base model. Osprey Extended Fit packs are the right choice if your apparel size is usually XXL or bigger. - Compatible with hydration systems, featuring hose ports - Rain cover included - Two ice axe loops - Zippered hip belt pockets
