Pack Smarter, Travel Lighter

Why You'll Want It

Your gear deserves more than a stuff sack. This system was designed to simplify your loadout, protect your essentials, and make the most of every liter. Whether you're overlanding, traveling, or hitting the trail, the Ultra setup delivers all the function with none of the drag.

  • All-Ultra Build: Constructed entirely from TX50 Ultra™—a 3-layer waterproof fabric that punches way above its weight.
  • Streamlined Packing: Everything fits inside your RUX 70L or 40L. Minimalist design, maximum utility.
  • Built to Organize: Clip, lash, and stack your system however you pack. Your setup, dialed.
  • Tough, Not Bulky: Durable, tear-resistant, and abrasion-tested—without the bulk of traditional gear bags.
