The Osprey Archeon 45 Men’s is a 45-liter trekking backpack aimed at overnight or multi-day hikes. It’s built to carry all the essentials you need on the trail while keeping the overall profile and weight in check.
This pack offers adjustable torso sizing—43–53 cm on the S/M frame or 48–58.5 cm on the L/XL frame—so you can customize how it sits on your back and hips. It measures 71 × 38 × 30 cm, giving you a streamlined yet roomy hold for clothing, food and gear. A detachable rain cover stows away neatly until you need it, and with a carry weight of about 2.2 kg you get solid construction without too much extra bulk.
