Ultra lightweight backpack

The goal of ultralight backpacking is to reduce the weight of your basic persistent stuff to under 10 pounds (4.5 kg). For hiking, the lighter your load, the more enjoyment. A key component to bringing the weight down is a super lightweight backpack. One of the lightest functional packs is the Zpack Nero 38 Liter, the one I use, which weighs 10.5 ounces (under 300 g). It’s a dry bag so no rain shell is needed. Empty, it will fold into a gallon Ziplock bag. — KK
