What to Compare Before Buying
- Capacity: This model is stated as 40 litres. Compare that with the amount of food, drink and accessories you need to carry.

- Storage space: The stated maximum dimensions are 31 x 20 x 64 cm. Compare that with the space you have at home, in a car or in luggage.
- Carry style: The backpack format, padded shoulder strap and chest strap matter if you plan to carry the load by hand-free transport rather than by handle.
- Leakproof and waterproof features: The bag is described with both leakproof and waterproof features, so compare those details with the sort of contents you plan to carry.
Before You Decide
Check that the 40 litre size, the expandable top section and the backpack format match the way you plan to carry food and drinks. If the bag must fit a particular storage space, compare the stated dimensions before choosing.
