ALSEYE 21L Gravestone Backpack 2 in 1 accessory

SKU CH-HGFZ-Z5JED

A 21-litre water-resistant backpack with a laptop sleeve and separate shoe compartment

  • 21 L capacity fits gym gear and laptop
  • dedicated laptop sleeve protects device on the move
  • separate shoe compartment keeps footwear away from clean items
  • water-resistant 900D TPU-coated polyester shields contents from rain
  • 100 % polyester construction delivers lightweight durability

Everyday Carry Backpack

The ALSEYE 21L Gravestone Backpack is a 2-in-1 accessory built for daily transport and gym use. It combines a 21-litre main volume with a dedicated laptop sleeve so work devices and training gear stay together. Water-resistant 900D TPU-coated polyester protects contents from rain and moisture. The design suits commuters, athletes and travellers who want one bag for multiple scenarios.

Organised Storage Layout

A separate shoe compartment keeps footwear isolated from clean clothing and electronics. Quick-access pockets place frequently used items within reach without opening the main compartment. Internal compartmentalisation prevents gear from shifting during movement. Buyers who need a dedicated camera cube or a hydration bladder sleeve will not find those provisions here.

Build And Carry Implications

Premium 100% polyester construction with TPU coating resists abrasion and repels water in daily exposure. The 21-litre capacity fits within typical carry-on limits for light travel. Padded laptop sleeve positions the device close to the back for balanced weight distribution. Users who require external MOLLE webbing or a rigid frame sheet will need a different pack.

Questions about this item

Will the water-resistant coating on the 900D TPU polyester need reapplication?

The 900D TPU coated 100% polyester fabric provides built-in water resistance that does not require separate reproofing treatments.

What limits how much gear the 21-liter main compartment can hold during extended trips?

The 21-liter capacity sets the hard volume limit; the internal compartments and shoe pocket help organise contents within that space.

Does the water-resistant material trap heat when the backpack is worn all day?

The 900D TPU coated polyester shell is designed for weather protection; ventilation depends on the back-panel padding and strap design rather than the fabric itself.
