Arc'teryx Internal Frame Backpacks

Types of packs

Backpacking packs can be 30 to 70-plus liters. To choose the right capacity, consider trip duration and the gear you’ll bring.

Backpack features
Think about the frame type, location of important pockets, padding and ventilation, among other things.

Backpack fit
Your pack should be correctly sized for your torso length (not overall height) and hip circumference. A fit-expert at an REI store can help.

By Activity

• Hiking: can hold a water reservoir and available in different torso sizes for right fit
• Climbing: narrow profile, abrasion-resistant reinforcements
• Traveling: pockets or compartments for organization, carry-on size

Capacity

• Packs that hold 20L or less are best for runs, day hikes, mountain biking or short trips.
• Packs between 20–35L are great for longer day hikes and as a travel carry-on.
• Packs holding 35–50L work for extended trips and mountaineering or climbing that calls for extra equipment.

Fit

The right daypack fit offers:

• A size appropriate for your torso length (not your overall height)
• A comfortably snug grip on your hips
