Gear Institute awarded the Lutsen 45 Best in Class for overnight backpacks (20-45L). All of the packs tested were taken on 2-3 night backpacking trips or 3-hour training missions in hot conditions and on rocky terrain. Each pack that went through testing was loaded up with 25 lbs worth of gear to simulate a weekend long trip and was evaluated for comfort/fit, stability, storage and durability.
