Taking full advantage of the Siletz' 35 Liters of water-tight storage is its incredibly versatile suite of complimentary modular accessories. The full range of accessories are organized into two separate, integrated accessory systems that we painstakingly designed to help you seamlessly transition between the various aspects of your life. The components of each system are designed to slide effortlessly into the Siletz and work in unison. The Night Bag/Gear Pouch is part of the Work and Travel System and integrates simultaneously with the Laptop Sleeve and Travel/Photo Insert within the Siletz 35L Waterproof backpack. It also is compatible for simultaneous carry with the Outdoor System’s Cooler Insert and Wet/Dry insert. Designed as a simple and efficient way to carry personal essentials for 3-5 days of travel (or more) the Night Bag is an incredibly utilitarian solution to carry or organize smaller items or toiletries. With stretch mesh internal organization pockets, a key ring, and D-ring handle, it is also equipped with our MOD.U.LOX® storage hardware, so it can be snapped into place within the Siletz 35L for rattle/free storage.
