Gear Review: Kakwa 55 Ultra200X Backpack by Durston Gear
Looking for a tough, ultralight backpack that can handle alpine missions and desert hikes alike? The Kakwa 55 Ultra200X by Durston Gear delivers big-mile comfort, bomber materials, and minimalist design that works. Here’s why it’s my go-to for serious trips.
Some gear changes how you move through the mountains. The Kakwa 55 Ultra200X Backpack by Durston Gear is one of those rare pieces that works with no fuss, no frills, and no question that it's built by someone who gets it! And that would be Mr. Dan Durston.
I’ve hauled this pack up steep 14ers in the Sangres, through blowdowns in the San Juans, and along hot canyon routes in Utah. Every trip it’s proven itself to be not only ultralight but quite comfortable and reliable.
Standout Features
- Ultra200X fabric – lighter and stronger than traditional Dyneema
- Full internal frame – provides real support even when fully loaded
- Streamlined design – no unnecessary extras, just trail-ready function
- Exceptional weight-to-performance ratio – under 1.9 lbs for a medium
I was skeptical at first, as so many ultralight packs sacrifice comfort for ounces. Especially when they're loaded up with lots of gear. But this one carries my full setup well. The load transfer is solid, the back panel breathes pretty well, and the wide shoulder straps are a win for longer days. It’s one of the few truly ultralight packs I’ve used that can comfortably carry 35+ pounds.
Whether I’m scrambling through talus or picking my way down loose desert slopes, the Kakwa stays put and keeps things stable. This backpack has a tapered shape, where the bottom of the pack is more narrow than the top. This is a unique design that helps to keep your load balanced out on your back.
What It’s Best For
- Long-distance backpacking
- Ultralight but rugged alpine missions
- Desert trips and hot-weather hikes
- People who want structure and real durability in an ultralight package
