Important Notes
A hydration bladder is not included—only the internal sleeve for up to 2L capacity. The backpack is made from durable, water-resistant materials but is not fully waterproof; it protects against light rain and splashes only. Reinforced stress points enhance long-term durability, and zippers are rigorously tested for reliability. Care should be taken to avoid abrasion with sharp objects to maintain performance over time.
