Best Backpacks for Thru Hiking the Appalachian Trail 2026: Top Picks
Long days, steep climbs, and changing weather. If you’re planning a thru hike on the Appalachian Trail, you know your backpack matters.
Picking the right pack can feel overwhelming. There are so many sizes, designs, and features. Some are lightweight but lack space, others hold everything but weigh you down. You face choices between comfort and durability, storage and simplicity. Budget packs often skip extras, while premium options can be expensive or overbuilt for some hikers.
This guide will help you see what matters for your hike, so you can find a backpack that fits your journey.
What Actually Matters When Choosing

The products below are grouped to show different types and capacities. Each suits a different kind of hiker. There is no single best—your needs decide what works for you.
