There’s probably no official definition for a lightweight or ultralight backpack. If there was, it would likely change as backpacking gear get lighter. What used to be lightweight 10 years ago might be too heavy for today’s standard.
Until recently, I thought the lightest internal frame backpack you can find today was Lowe Alpine’s Zepton 50XL at just 2 lbs 10 oz but it looks like Jason Klass, a backpacking gear fanatic, knew others that are much lighter. Three of the Top 5 are internal frame bacpacks (Catalyst, Mariposa Plus, Mountainsmith Ghost).
It’s not just about weight though. Features play a big role in getting these lightweight backpacks into the Top 5.
