What fits inside

The sling bag holds a main compartment with layered partitions, a dedicated foam sleeve for an 8.5 inch tablet, a headphone holder, a retractable keychain and individual slots for wallet, pen and power bank. Its 4.7 litre volume can carry two 650 ml bottles while weighing 1.3 lb. The 12 by 6.68 by 3.5 in frame keeps daily essentials organised without bulk.

Built-in charging convenience

A hidden USB 3.0 connector on the side creates a pass-through link between a power bank stored inside and a phone outside, letting you charge on the move without exposing cables. The dustproof and waterproof port cover protects the contact when not in use, and the wrapped rear structure adds a concealed pocket for valuables.

Weather-resistant polyester shell

The outer material uses a multi-layer wear-resistant construction that repels water and absorbs shock, protecting electronics from rain and knocks. The crossbody strap distributes weight across the chest or back, and the compact 3.5 in depth keeps the bag close to the body for stable carry during travel or commuting.

The bag holds up to 4.7 L total volume, including space for two 650 ml bottles, an 8.5 inch tablet sleeve and organised pockets for wallet, power bank and keys.
