What to Pack
Prioritize: phone, wallet, keys, medications, and any electronics. A 10L bag fits a phone, wallet, keys, and a light jacket. A 20L bag adds a change of clothes and snacks. A 40L bag works as a full day pack.
How to Seal It
Roll the top down at least 3 times — 4 or 5 rolls is better. Then clip the buckle. A properly sealed dry bag will keep contents dry even if the bag is fully submerged for several minutes.
