Osprey Aether Plus 100 Men's

The Osprey Aether Plus 100 is a full-featured 100-liter expedition pack (98 L main compartment) built for multi-day treks and mountaineering trips that require carrying a large volume of gear. The padded Contact back system sits directly against the back rather than using ventilated mesh, giving better load transfer to the hips under heavy weight at the cost of some breathability. The pack has two ice axe loops, front and side pockets, and an integrated rain cover, built from durable 210D nylon with bluesign approval and PFC-free DWR. At 2892 g for 100 L, that works out to roughly 28.9 g per liter — a reasonable figure at this volume given the sturdier construction needed for heavy expedition loads. It suits mountaineers and long expedition trips that require carrying substantial gear, including technical equipment like an ice axe. For standard lightweight trekking, 100 L is more capacity — and weight — than most hikers need.
