Conquering steep rocky pitches on day two of your solo-backpacking trip into the Cascades might be daunting to some, but with your know-how, strength, and Osprey Aether Pro 70 Backpack you feel downright unstoppable. This pack falls as far into the "featherweight" category as a 70-liter can, weighing in under 4lbs (size medium), so you can pack in all of your necessities without being weighed down. It features the newly reworked back panel and Lightwire Suspension system that makes heavy loads feel more manageable while you dive deeper into the backcountry by using a lightweight aluminum frame to transfer your load to your hip belt, alleviating pressure on your shoulders and back while you pick your way through overgrown trails to the next valley where you'll spend the night. To make sure you're fully prepared for whatever adventure you choose, the pack is equipped with ample straps for carrying sleeping pads, trekking poles, and ice tools, so you're not limited with your choices. An internal pocket offers space to add up to a 3-liter reservoir for added hydration, and pockets at the hip belt give you quick access to your maps and snacks. On back you can add an additional Osprey Daylite pack or Alpine Pocket, so you can go for quick out-and-back day hikes once you've set up your base camp, without the need for lugging your whole pack along on the trip. If you're going for streamlined, the Aether has the answer for you with a removable top lid, removable ice tool loops, removable side compression straps, and removable sleeping pad straps, so you can shed weight as needed, while still carrying the gear you need for an overnighter or weekend expedition.
