The PRO LT packs are ideal for the hunters looking for the lightest pack possible but unwilling to sacrifice pack organization and durability. PRO LT (Light and Tough) packs leverage a lightweight high-tenacity CORDURA® 330 denier fabric, paired with coated fabric paneling for added water and abrasion resistance.

All PRO LT Packs feature a built-in load sling mode, which expands an extra 2500 cubic inches of storage between the frame and bag for hauling meat or gear. PRO LT Packs are hydration compatible with up to three-liter water reservoirs. Packs are shipped fully assembled in your choice of color, frame size, and waist belt size.

Leveraging our most comfortable and durable suspension set ever, the PRO Suspension features wide and soft shoulder straps, profile-adjustable hip belt, height-adjustable lumbar, and a center-pull belt adjustment system. In addition, an improved odor-resistant and highly durable spacer air mesh is used for ultimate comfort and breathability.

Weighing only 11 ounces, the patented KUIU Carbon Fiber Frame is the weight-bearing backbone of the PRO Pack System—capable of hauling up to 150 pounds. The frame features a four-inch vertical shoulder strap adjustment range and offered in three torso height sizes for a customizable fit.

All PRO LT Packs are made with the gold standard in materials, like high-tenacity CORDURA® 330D fabric, robust YKK® Zippers, Duraflex® Hardware, Hypalon anchored compression straps, and Chomarat® Spread Tow Carbon Fiber.
