Arc'Teryx Advanced Composite Construction
Advanced Composite Construction
Advanced Composite Construction features an innovative weatherproof bondable fabric, custom molded components and a compact suspension system. These packs are constructed with ACT420, a unique airtight 420-denier fabric laminate that enables  components to be fused directly to its surface. Leveraging these bondable properties, a foam, plastic and aluminum tri-laminate structure forms a Monoframe backpanel to create a direct link between spine, suspension and bag. These packs are seam-sealed and combined with a roll top closure to provide total weatherproof protection.
