The 10 best ultralight hiking backpacks that won’t stress your back

If you’re a seasoned trekker, I’m sure you’ve had your share of aches, pains, and “holy crap I’m dying” moments while hauling your jumbo hiking backpack into the woods. Today, we’ll look at how you can ditch those pains with an ultralight backpack.

Back in the day, ultralight backpacking simply meant “toss a tarp and some hardy snacks in a bag and get ‘er done.” That’s no longer the case because ultralight backpacks allow you to carry your creature comforts to remote locations — without going full Bear Grylls.

So how do you find the best pack for your trail-traversing tendencies? Of course, the most important factor is weight, but other considerations include capacity, comfort, and durability. Let’s break it all down so you can climb some mountains without breaking your back.

Traditional hiking backpacks usually come with a full frame (external or internal), multiple compartments, and lots of pockets, zippers, padding, and heavy fabrics. It can be difficult to lighten your load with traditional packs since they already weigh several pounds while empty. Plus, all the extra pockets and compartments make it easier to overpack.

Ultralight backpacks only include features with an intentional purpose. Though these backpacks cut down on zippers, straps, and compartments, what you’re left with will serve you much better on the trail. That’s why ultralight packs weigh around two pounds or less, but still stand up against long journeys. They’re constructed from modern laminate fabrics, like Dyneema and Tyvek, that offer the durability of heavier fabrics without adding weight.

You’ll find ultralight backpacks are full of thoughtful features catered to adventurers, and still provide extreme durability and comfort. Just keep this in mind: most ultralight backpacks perform best with a maximum load of 35 pounds or less.
