Security backpack with hidden zippers | Kalsten

The hand in the pocket – and the wallet is gone.

Anyone who travels daily by train or walks through busy city centers knows the uneasy feeling in the crowd: A brief moment of inattention, and important things disappear unnoticed. This backpack secures its main compartments against the back – the zippers are located on the back, directly at the wearer's back, completely inaccessible to outsiders. Laptop, wallet, and documents stay exactly where they belong.

Advantages

• No more grabbing possible: Since the zippers are hidden at the back, pickpockets can't reach into the main compartment unnoticed – even in the densest crowd.
• No more packing and unpacking: The padded laptop compartment safely holds laptops up to 15 inches, so no separate carrying bag or additional protection is necessary.
• No more worries about wet contents: The water-repellent polyester keeps rain out, so laptops, documents, and electronics remain dry even in bad weather.

Specifications

• Material: Water-repellent polyester
• Laptop compartment: Padded, for laptops up to 15 inches
• Colors: Black, Blue, Black Brown
• Carrying style: Backpack or Sling Bag
• Special feature: Hidden zippers on the back

Application

1. Packing: Place the laptop in the padded compartment and sort cards and phone into the inner pockets.
2. Wearing: Wear the backpack with the hidden zippers towards the center of your body – the compartments will then be against your back and inaccessible from the outside.
3. On the go: On the train, at markets, or in busy places, simply leave the backpack on – no need to turn around or hold on.

Pro Tip: If you wear the backpack as a sling bag, turn the main compartment towards the front of your body – this way, the contents are always in view, even in very crowded areas.
