Highly Water Resistant

Versatile Roll-Top Closure

Secure Front Pocket

Interior Laptop Compartment

Shoulder Strap Pockets

Features:

  • Zippered Front Pocket with Brightly Colored Lining

    Thru-hikers may prefer open, mesh front pockets, but a pack intended for a multitude of use-cases needs a secure pocket. Bright lining aids visibility of stored items.

  • Shoulder Strap Pockets

    Keep essentials near. Phone, sunglasses, keys—poop bags.

  • Roll Top

    Variable volume main compartment. Buckles aid a slim profile while carrying a light load. The long top strap secures contents when carrying a larger load.

  • Adjustable Sternum Strap

    Walking from the grocery store or walking through the mountains, sometimes the situation calls for a more secure fit.

  • Large Main Compartment with Laptop Sleeve

    A padded divider organizes, a computer, folders, or notebooks.

  • UltraStretch Side Pockets

    Super durable mix of UHMWPE and quality Nylon 6 Lycra for storing bottles, bike locks, or baguettes.
