The Osprey Aether Pro 75L Backpack is made for those who give multi-day timeframes for when they'll return and need to haul plenty of gear wherever they're headed. The pack is built to withstand harsh, rugged conditions, from glacial stream crossings to technical ascents up rock and ice. The durable NanoFly fabric is reinforced with a triple-grid UHMWPE ripstop to power through scrapes and scratches while keeping our gear safe. The suspension is built to be fully customizable, ensuring we're comfortable as we methodically work our way up prominent peaks and across vast stretches of unforgiving terrain. The versatile design lets us strip the top lid, hip belt pockets, and side compression straps for a fully optimized pack ready to take on whatever adventure awaits.
