KUIU Carbon Fiber Frame | Carbon Fiber

As the weight-bearing backbone of our modular pack system, the KUIU Carbon Fiber Frame connects the PRO Suspension to your choice of any PRO or PRO LT pack bags. The Frame is available in three different sizes: Reg 22u2033 | Tall 24u2033 | Xtra Tall 26u2033. Reference the size guide to determine your correct size. Each size of frame has 4u2033 of vertical shoulder strap adjustment, ensuring a perfect fit. The internal structure of the KUIU Carbon Fiber Frame has changed significantly with the introduction of Spread Tow technology. Traditional carbon construction uses woven strands of round carbon fibers, however, this process uses less carbon and more resin than what's ideal. With Spread Tow technology, the carbon fibers are flattened and stitched together, giving increased strength by eliminating pockets of weaker resin material. Spread Tow sheet angles are also offset to change the frame's rigidity and performance. The patented molded KUIU Carbon Fiber Frame includes a complex internal structure of foam core, offset and straight Spread Tow layers, with stacked truss supports to optimize strength and flex as needed throughout the frame.
