One of The North Face's most popular dayhiking packs, the Angstrom 30 is an ultralight, versatile pack that is comfortable on the trail, but can be used everyday around town as well. As compared to normal daypacks the Angstrom 30 has a more advanced shoulder harness, padded hipbelt, and lumbar padding. The Angstrom 30 is also hydration compatible, there are water bottle pockets, and it comes with a zippered rain cover pocket with rain cover included. The sternum strap helps secure the pack on variable terrain and The North Face has built a safety whistle into the buckle.
