Scream 55L Backpack

Whether you're fast-packing through Colorado's Front Range or trekking the section of the Appalachian Trail from Falls Village, CT to the Massachusetts-Vermont state line, the Mountainsmith Scream 55 Backpack offers lightweight performance and just enough room for the necessities. Ideal for fast-paced backpacking trips that require a light load, the Scream 55 is outfitted with a myriad of packing-friendly features ranging from its removable, foam suspension sheet to the lightweight and durable Robic fabric.

Weighing in at under three pounds, the Scream features lightly padded shoulder straps and load lifter adjustment points that ensure a fine-tuned fit, while the padded, forward-pull waist belt further alleviates your load. Additionally, the waist belt boasts dual-zipper pockets that are smartphone friendly. An internal hydration sleeve is designed to accommodate a three-liter reservoir, and the roll-top closure makes it easy to access gear in a hurry. Not to mention, the two front storage pockets fit a minimalist tent, and the side mesh pockets store most 32oz water bottles so you can stay properly hydrated.
