Best overall
Sleeping bag dry, clothes sorted, one bag for the wet things
Sea to Summit Lightweight Dry Sack (set)
Siliconised nylon, 4 L / 8 L / 13 L
Colour-coded bags turn a duffel from a heap into something you can find things in at 5 a.m., and they keep your down dry when the duffel spends four hours on a bus roof in rain — they are not submersion-proof, so a river crossing still needs care.
Finding things in the dark stops being a fight
Real protection against a wet bus roof
Weigh almost nothing
Not submersion-rated despite the name
Silicone coating eventually delaminates
Expensive against a bin liner
Not for you if: Anyone on a tight budget. Two heavy-duty bin liners do eighty per cent of this for nothing.
