Round two of our cult-favorite Spider Bag sees refinements throughout, most notably in the form of more weatherproof fabrics and increased functionality. The bag was originally unveiled as a stripped-down, aerodynamic backpack for urban commuters, but moto riders soon adopted it, along with a core group of road cyclists who started using it to supplement their jersey pockets for mammoth training rides in the mountains. There's truly nothing quite like the Spider Bag out there, as its barely-there design is suspended by a harness made with raw-cut, super flexible straps that disappear against your outer layer for maximum comfort and flexibility. The main 3-liter pocket itself is now constructed with our rain-jacket-proven Schloss Tex and NEOS Mild, locking out the weather with its 3L waterproof softshell. We've also included an internal Ramp Pocket and key clip for added organization, a reflective zipper for increased visibility, and a 3D Net back panel for boosted ventilation.
