Buying Guide for Multi Day Hiking Backpacks
Capacity and Size
For multi day hikes, you generally need a pack between 50 and 70 liters. This provides enough space for a tent, sleeping bag, food, water, and clothing without being overly bulky. The Teton 55L Scout falls right in this sweet spot, offering ample room for weekend trips or longer treks if you pack efficiently. For shorter overnights or ultralight setups, a smaller pack like the Lightweight Hydration Backpack (12 liters) may suffice, but it is best for day hikes or minimalists.
Comfort and Fit
A comfortable backpack ensures you can hike longer without pain. Look for adjustable torso lengths, padded hip belts, and breathable back panels. The Teton 55L Scout features a multi position torso adjustment and a durable open cell foam lumbar pad with molded channels for airflow. This design fits medium and tall adventurers well.
