This is how a lot of people actually get into ultralight
I love talking about this pack because it represents something good happening in the gear world. Ultralight used to be gatekept by price. You wanted a light setup, you paid premium money, end of conversation. The Qi Dian Pro is part of the wave that broke that open, and I'm genuinely glad about it.
The headline feature is 46+10L expandable capacity in a lightweight, frameless-oriented design. The advantage is obvious ā you carry less pack weight, so more of your allowance goes to things you actually use. The benefit is the one nobody mentions until they've felt it: a lighter pack changes what a day feels like at mile fourteen, not mile two.
The roll-top closure does the compression work. Cinch it down as your food bag empties and the pack tightens with the load instead of flapping around half-full. Add external compression straps and you've got a bag that rides as a single stable mass, which is most of what stability under load actually means. Storage is the trail-first arrangement I'd want. A large front mesh pocket for the wet fly, the shed layer, the rubbish you're packing out. Oversized side pockets that take full bottles you can reach without taking the pack off. And a deliberately minimal internal structure, because every internal divider is fabric, and fabric is weight.
The wide padded hip belt is the part I'd underline, because a lot of budget ultralight packs skimp exactly here. A proper wide belt is what lets a frameless-oriented pack carry a resupply-day load without folding into your lower back. It's not a premium suspension system and I won't pretend it is ā but it's meaningfully better than the token webbing you find at this price point.
Ripstop technical fabric handles the abrasion of a real trail. Here's my repair-minded note: ripstop is called that because a tear stops at the grid rather than running. Carry a few inches of gear tape and you can field-fix almost anything on this pack in five minutes. That's a real advantage of simple construction ā there's less to go wrong, and what does go wrong, you can fix yourself at camp.
The honest limit: frameless-oriented means your base weight has to be reasonable. Load this thing like a traditional 50L pack and you'll have a bad time, and that's true of every pack in the category regardless of price.
But if you've been curious about going lighter and the cost was the wall ā the wall's gone. Grab it, cut your base weight, and go find out how far you can walk when your pack stops fighting you.
