Radix 57L Backpack - Men's

What Our Gearhead® Experts Are Saying:

"I grabbed the Radix 57L for a mixed-weather loop and was stoked on how it carries. The removable frame adds real support when I’m hauling a bear can, but I can strip it to go fast and light. The big side pockets swallow bottles, the hipbelt pockets fit phone and snacks, and the off-center zip lets me reach layers without yard-saling my kit."

We load up the Mystery Ranch Radix 57L Backpack when the itinerary calls for long approaches, variable weather, and a clean, efficient carry. Ultra-PE Birdseye panels and recycled Robic ripstop balance low weight with hard-wearing durability, while the removable aluminum frame brings the structure we want for three- to five-day loads.

Thoughtful storage keeps our flow dialed: a roomy lid pocket, a front shove-it for wet layers, deep side stash pockets for bottles or a shelter, and dual hipbelt pockets for on-the-move essentials. Compression straps tame bulk, trekking pole carry keeps our hands free on scrambles, and the adjustable harness fine-tunes fit so miles stay comfortable. Hydration compatibility rounds out this trail-ready hauler for big-mile missions.
