Bag protector

Quick delivery, good communication. Product works brilliantly on a rainy day to protect bag and belongings. Easy to store in bag for another rainy day.

Rucksack cover

Seem good quality at very reasonable price, even better as they were on deal (although that wasn’t clear). Sizing was a bit iffy, went for medium which fits fine on normal sized back packs. Haven’t tried in the rain yet!
