What Features Should I Focus on when Choosing the Best Backpack for Appalachian Trail thru-hiking?

Hikers on trail

Pack Weight

Your pack will be one of the heaviest, and most necessary items you carry. Choose carefully.

Your pack is one item where you can easily shave some weight.

Those who have lighter packs put less stress on their bodies and are more efficient, enabling them to hike the same distance in less time.

Because the Appalachian trail has resupply points every 3 to 6 days, you should not have to pack as much food and other supplies as you would on other thru-hike trails.

It is common for new hikers to begin to ditch gear in the first week and wish they had chosen lighter packs.

Backpack Frame

The vast majority of backpackers successfully thru-hiking the Appalachian trail do so using internal frame packs.

Those who start with external frames often switch to internal frames at some point.

Those who use frameless packs usually have ultralight packs and gear.

You don’ want to waste money and resources by switching packs, so consider your options realistically and carefully.

Pack Durability

The Appalachian Trail includes a variety of terrain and you will find yourself climbing boulders, using branches, tree limbs and roots to ascend and descend, encounter wet weather and possibly freezing conditions.

While an inexpensive hiking pack saves money up front, a pack that gets damaged or torn will need repair or replacement and can end up costing more over the span of the hike.

The best backpack for Appalachian trail thru-hiking is one that will last the nearly 2,200 miles without needing repair or replacement.

hiking trail and mountains


In recent years, the trail has been warmer, which may mean you can pack lighter, but this has led to water being somewhat less abundant.

So you need to consider how you will stay hydrated and how much water you will need for food.

Most folks who thru-hike head north on the trail starting in Georgia and finishing in Maine.

This allows them to follow the warm weather as they head north. It also means that if they plan their trip right they may be able to get away with packing lighter, needing fewer layers and using a summer sleeping bag for some of the trips.

As summer nears and weather warms up, you may be able to shed extra clothing and cold weather supplies.

The best backpack for hiking the Appalachian trail is one that is light enough to be comfortable, but roomy enough to carry necessities like water and supplies for colder weather.

Hauling Food

The Appalachian Trail has many re-supply points and you should only need to carry around three days to six days worth of food with you in your pack at one time.

Over packing is the number one mistake made by novice thru-hikers and the Appalachian trail has conditions that make it easier to carry less.

In the event you do forget something or decide you want to pick up supplies you should reach an outfitter about every 7 to 14 days. By hauling less, you will have a lighter more comfortable pack, and you will not need a huge pack.

The best backpack for Appalachian trail thru-hiking is the smallest one you can carry while still packing the necessities.


The pack should be able to adjust to you and your capacity needs. Many hikers lose weight while on the thru-hike so the adjustment straps need to be comfortable and adjustable.

Appetites also change and hikers find they want to carry more food so being able to expand the pack might be something you want to do.

At some point you may also want to decrease the capacity so a pack with compression straps and other size adjustments will help.

Osprey Men’s Levity 60 Backpack

It’s hard to get away from these Osprey packs! They are just so reliable and hard to beat.

And, now that ultralight hiking is becoming more popular, being seen by some as the only way to go, it makes sense that Osprey would be starting to introduce its own range of ultralight packs.

The Levity is the latest Men’s ultralight pack to be released by Osprey (the Lumina is the women’s version).

Essentially a lighter version of the Exos, weighing in at just 1 lb 13 oz, the Levity is an ideal ultralight thru-hiking backpack.

A reliable lightweight option for AT thru-hikers who want to take the ultralight approach.

Gregory Mountain Products Men’s Baltoro 65 Backpack

Designed for heavy loads, the Baltoro 65 is fitted with a heavy duty suspension and padding.

  • Comes with an integrated rain cover.
  • Has more pockets that you would know how to fill and generally excellent gear organization.

Likely to be too heavy for most thru-hikers, it may suit you if you’re looking to complete the AT over a slightly longer time period and want to carry more gear than the ultralight movement would have you packing.
