Shelfflex Anti-Theft Crossbody Sling Bag – Waterproof USB Charging

Overview

Whether you're commuting to work, running errands, or heading out on a short trip, this Anti-Theft Crossbody Sling Bag is built to keep your essentials organized, protected, and within easy reach. Made from durable Oxford cloth, it combines a water-resistant build with a combination lock and a built-in USB charging port, making it a practical choice for anyone who wants secure, hands-free carrying.

The anti-theft design centres on a numbered combination lock built into the side panel, which secures the main zipper so the bag cannot simply be opened behind you on a crowded train or busy street. Just below it sits an external USB port wired to the inside of the bag: connect your own power bank inside, and you can charge your phone from the outside without opening anything up.

Inside, the bag has a dedicated mobile phone pocket, document pocket, and computer pocket, giving your devices and paperwork their own protected space instead of getting jumbled together. Its square vertical shape and soft-surface finish give it a clean, structured look, while the single strap and soft handle offer flexible carrying options depending on how you like to wear it.

Key Features

• Combination Lock – A numbered dial lock built into the side panel secures the main zipper against opportunistic opening.
• External USB Charging Port – An outside port wired to an internal connector lets you charge your phone from your own power bank without opening the bag.
• Water-Resistant Oxford Cloth – Durable Oxford fabric designed to resist water, helping protect your belongings in wet weather.
• Organized Interior Layout – Separate mobile phone pocket, document pocket, and computer pocket keep your items sorted and protected.

• Crossbody Sling Design – A single-strap sling design allows for comfortable, hands-free carrying across the chest or shoulder.
• Soft Handle & Medium Hardness – A soft carrying handle paired with a medium-hardness structure balances comfort with shape retention.
• Inner Patch Pocket with Polyester Lining – An additional inner patch pocket adds extra storage and organization inside the main compartment.
• Multiple Colour Options – Available in Black, Army Green, Blue, Camouflage, Grey and New Blue.
