Inspired and tested while climbing Lassen Peak in Northern California, the Lassen backpack is a MOLLE-compatible and CCW-compatible tactical backpack with 1800 cu. in. / 29L volume. Slightly different from Maxpedition's previous packs, the Lassen backpack uses YKK molded-tooth zippers, made with individually injected self-lubricating elements for low-maintenance, long-lasting use. Each backpack features a rigid frame with a user-configurable aluminum support for extra support. Frame and carrier can be separated and/or removed for significant weight reduction. Expandable bottle holders on both sides can hold hydration or other long/short objects such as tripods. Thoughtful design for comfortable carrying and easy access to your gear. Adjustable, removable waistbelt for added stability for most body sizes. Finally, this Maxpedition backpack features a large external loop field for attaching tape or your favorite patches!
