A middle-size expandable travel backpack for 2-3 days trips.

Expandable backpack: expandable capacity from 23 L - 39 L to accommodate enough room for a full change of clothes for 2 - 4 days, and also has enough room for your entire shower and grooming kit. It is equivalent to a 20" trolley case.

This backpack can be opened 180 degrees like a suitcase. Besides, a fully pull zipper design, a velcro opening structure could adjust the opening angle. To people who travel a lot, it is a boon to put a backpack 180 degrees open on the hotel floor or bed at any time.

Plenty of pockets and compartments: there are several exterior pockets and interior pockets to keep your accessories separate and organized. Including an anti-theft back pocket, a 15.6" laptop compartment, a dry wet storage pocket for your entire shower and grooming kit, etc.

A carry-on sized travel backpack: its dimensions are 16.5"×12.2"×6.3" for maxing out most airlines carry on limits, (small than airlines allow carry-on luggage that measures up to a maximum of 22" × 14" × 9").

TSA-friendly design with lay-flat capability, so it lays flat while it goes through security, making it easier to see and scan.

Designed with a gap in the middle of the back pad, you could fix the backpack to rolling luggage to reduce the burden on your back when you travel abroad.

A USB charge port is integrated on the side of the backpack, making it possible to charge your phone while on the go without opening your backpack. However, you will need to purchase a separate battery pack to use for charging your devices.

The exteriors use a durable and waterproof high-density Oxford fabric so that this backpack will stand the test of time.

Ergonomic airflow back design, with an adjustable anti-slip chest belt and quick-release shoulder strap, thick but soft multi-panel ventilated padding for added support and comfort, decreasing the pressure on the shoulder and neck.

A convertible travel backpack can be convertible into a handbag.

It is the absolute perfect travel companion for business travel trips, or weekend getaways when you need to haul your entire electronic life with you, and still have enough storage space for your clothes and gear.
