The Lightning Waist Pack is a streamlined, high-performance 2-liter belt engineered for long-distance efforts where efficiency and durability matter. Built with our EnduraMesh LT™, an ultralight 80% nylon / 20% UHMWPE blend featuring fibers stronger than steel, it offers exceptional abrasion resistance without added bulk.

Designed on our ErgoFit Waist™ foundation, its conical shape (wider at the bottom, narrower at the top) allows the belt to sit naturally on the hips with minimal movement. Six total pockets provide intuitive access: a front zip pocket for essentials, a rear quick-grab pocket behind the light-mount area, and a large main compartment that houses the included 625 mL Softflask with a low-profile 28mm locking cap to reduce body contact and prevent leaks.

Compatible with the UltrAspire Light Bracket for seamless use with the Lumen 600 5.0, Lumen 850 Duo, or Lumen 400z 3.0, the Lightning also features a toggle-controlled compression system to stabilize your load. Dedicated rear Z-pole attachments provide optional trekking-pole carry when the terrain demands it. It’s the ideal companion to larger packs like the Zygos 6.0, Traverse, or Purist. Available in three sizes. Includes a 625 mL Softflask. Light Bracket not included.

Available in three sizes for a secure fit. Sizing is based on waist measurements. Small (28–32"), Medium (29–33"), Large (31–36")
