POWER KING 30L to 40L Expandable Hiking Backpack, Brown, Roll Top, Fits 15.6-inch Laptop

Expandable roll-top hiking backpack for day trips and longer outings

A lightweight roll-top hiking backpack that expands from 30L to 40L, with multiple pockets, a breathable back panel and water-resistant X-PAC fabric.

The POWER KING hiking backpack is designed to give you a bit more room when you need it, with a roll-top build that expands from 30L to 40L. In the current listing, it is described as suitable for 3 to 4 day trips and as fitting a 15.6-inch laptop, so it works as a practical carry option for hiking, camping and travel.

Space that adjusts to the trip

The main compartment is paired with multiple pockets, which makes it easier to keep smaller items organised and close to hand. The roll-up top lets you change the capacity depending on what you are carrying, rather than committing to one fixed size.

• 30L capacity that expands to 40L
• Main compartment with multiple pockets
• Secure zip closure
• Fits a 15.6-inch laptop according to the listing

Built for carrying comfort

The backpack is described with a breathable back panel, adjustable shoulder straps, a chest strap and a waist belt. Those details suggest a design aimed at spreading weight more evenly across the body, which is useful on longer walks and full days out.

Materials and outdoor use

The listing says the bag is made from X-PAC diamond mesh composite fabric and describes it as water-resistant and scratch-resistant. It is presented as a backpack for hiking, camping and travel, with a maximum load capacity stated as 50L in the source content.

• Water-resistant according to the listing
• Scratch-resistant according to the listing
• Roll-top design with fastening buckle
• Brown colour

The stated unfolded size is 48 x 32 x 12 cm. Because the source information is limited, the most reliable way to judge it is by the listed capacity, the roll-top expansion, and whether the pocket layout suits the kit you normally carry.
