The Osprey Ultralight Drysac 3L is a water and dust proof stuff sack ideal for Cameraâ€™s and other smaller electronic equipment. Different colours for different sizes will also allow you to colour code your contents for even quicker access. Equipped with a fully waterproof roll-top closure, coated fabric and taped seams that keep your gear dry no matter how wet your pack gets. Unlike other drysacks they have a rectangular shape. This results in more efficient packing and when removed from your backpack, theyâ€™re able to stand unaided. An essential piece of kit whether adventuring in the Antarctic or out hiking in a balmy summerâ€™s afternoon.
