What to know before buying

Listing details to confirm

The listing specifies water resistance, while promotional text also calls the pack waterproof. Treat the stronger waterproof claim as unconfirmed, and verify which claim applies to the selected listing. The listed maximum device size of 22 inches is not a stated laptop-compartment measurement, so check fit against your device dimensions.

Frequently asked questions

How much can the Maelstrom Mslptbp13 hold?

The listing gives its capacity as 40 liters and describes four compartments and 20 pockets. Those figures describe the claimed configuration, not how much a particular load will weigh or fit.

Is this backpack waterproof?

The product details say water resistant, but promotional copy also uses waterproof. The stronger waterproof claim is not confirmed, so do not assume the pack protects contents in heavy rain or immersion.

Can I attach extra pouches?

The listing describes a front MOLLE mounting panel for compatible add-on pouches. It does not identify pouches as included.

Will a 22-inch laptop fit?

A maximum compatible device size of 22 inches is listed, and the pack is described as a laptop backpack. The actual laptop-compartment dimensions are not provided, so check the compartment fit before buying.
