The award-winning Alpha series is the pinnacle of design, functionality, and comfort. Now entering its fourth iteration, this pack has had unprecedented amounts of care and attention placed into every square inch. The new larger front pockets which feature a drawstring are perfect for holding any of our bottles. In addition, the Alpha 4.0 can also hold a 2L reservoir in its bladder compartment. The Alpha 4.0 features an insulated layer piece that can help keep your gear dry while it’s in the pack, cool you off, keep your fluids cool or warm, or you can remove the insulated layer altogether. For durability, this pack comes with reinforced bottom double-layer 30D fabrics. Easily access any essentials on the go with large passage pockets or zippered side pockets. Keep your phone safe in the front pocket with the securing strap. Available in three sizes for a more comfortable fit.
