@macrumors: This is the peak design 2-1 backpack. It’s literally TWO backpacks zipped together to form one mega backpack and it’s incredibly useful for mini trips where you need to pack a ton but don’t wanna bring larger luggage. Check it out here - https://peakdesign.kickbooster.me/boost/peak-design-travel-line This is NOT sponsored. Just really like the bag and what Peak Design does. They did provide this bag for me to check out but not required for me to post anything and all thoughts and opinions are my own
