To put Deuter’s updated-for-2024 Aircontact Ultra 50+5 ultralight backpack through the paces, I took it on a pair of quite rugged but also quite different backpacking trips this spring: a three-day hike through southern Utah’s Owl and Fish canyons with a max weight of about 30 pounds in the pack, and six days and about 60 miles backpacking the Grand Canyon’s Gems Route, repeatedly carrying extra water—and starting out with more than 40 pounds inside, including over 10 pounds of water and 11 pounds of food. As I expected, those trips revealed much about the Aircontact Ultra backpacks and why they might appeal to lightweight and ultralight backpackers.
