For my more regular adventures, the LiteAF 35L Frameless Ultralight Backpack has become my go-to choice. Clocking in at just the right size, this pack accommodates my ultralight gear setup effortlessly. Its durability has been put to the test on the Appalachian Trail and various other trails, covering over 500 miles, and it has exceeded my expectations.
The LiteAF 35L stands out for its simplicity and functionality. The frameless design maintains a feather-light feel while ensuring that essential features aren’t sacrificed. The pack fits like a glove, offering both comfort and freedom of movement on the trail. Whether navigating winding paths or traversing challenging terrain, the LiteAF 35L has proven to be a reliable companion.

It seems to hold about 50L. I am 180cm tall and size medium. It was perfectly waterproof and well made. It’s sturdy and lightweight.

Love this pack. I already had a 40L dyneema curve from a few years back and wanted to get one of the new ultra 200 packs with the ungraded hip belt style. I’m a big guy and the fit of this pack is perfect. I love the ultra fabric. It feels incredibly substantial yet flexible. I’ve only put it through a few days on trail but it feels like it will hold up for the long haul. I can’t speak enough about the fit. I’m a big fan of how the load sits, it all but disappears. If your a fan of compact and lightweight gear, this frameless pack is right for you. If you’ve been wanting to try out an ultralight pack, don’t hesitate!
