Fit is the most important feature of your pack. After that, it's all personal choice (size, weight, available side pouches, stowage, etc). Selecting the right backpack is vital for a successful Camino journey. Choose a lightweight, durable backpack with a capacity of 30-40 liters, which is sufficient to carry all your essentials without being overly burdensome. Look for a design with adjustable, padded shoulder straps, a hip belt, and a ventilated back panel to ensure comfort and support during long walks. Multiple compartments and external pockets can help keep your gear organized and easily accessible. Features such as a hydration sleeve, rain cover, and attachment points for trekking poles can enhance convenience. Ensure the backpack fits well and distribute weight evenly to prevent strain and discomfort. A well-chosen backpack is your best companion on the Camino.
