So you're on a longish holiday living out of a backpack or suitcase where packing space is at a premium so you don't want to take another rucksack. You're also doing side trips where you return to the same place that night but obviously don't want to take your backpack/suitcase along. Here's the solution, a 20 litre sack that will hold everything you need for a day, but folds down to the size of your hand when you don't need it. A great idea.

• Folds into its own pocket
• 210D ripstop nylon
• Highly water resistant
• 20 litres capacity
• 17 x 13cm packed size
