Description
The Aether Plus 100 is the largest pack Osprey makes, built around a heavier frame for the trips where the load is the problem: winter kit, week-long resupplies, a share of somebody else's tent. It carries 40–70 lb with the weight held tight to your back rather than hanging off it.
The top lid detaches and becomes a DayLid daypack for summit pushes and side trips, and Custom Fit-on-the-Fly adjustment at the shoulders and hips tunes the fit under full load. Two torso sizes, S/M and L/XL.
