Took 25l backpack into store and tried this. seemed too small, but fitted well, if tight, which i guess is what you want.

Needed a waterproof cover for a merlin 35l back pack amd to fit my bike back pack, this does both. ideal.

Can't see it fitting a 30l one though.

Recently visited austria, loads of rain in the mountains and the cover performed really well at keeping rucksack contents dry. also finding this cover very useful when using the cycle, gives rain protection and good visibility
