POSO Vacuum Compression Backpack with 17.3-Inch Laptop Sleeve

For a trip where clothing takes up more room than the rest of your gear, this backpack adds a vacuum-compression compartment to a travel-friendly layout. The included pump is intended to reduce the bulk of packed clothes, while separate sections keep a laptop, shoes, and smaller items apart. That setup is more involved than a basic backpack, but it may help if you want to carry a larger load without switching to a suitcase. One detail needs attention before choosing: the product name says 60L, while the description gives a capacity range of 35L to 50L.

Technical details

The bag is described as expandable from 35L to 50L, with a vacuum compartment and an included pump. The maker claims clothing volume can be reduced by up to 50%, that figure is a stated claim, not a guarantee for every load. There are three main compartments, a padded laptop sleeve listed for laptops up to 17.3 inches, organizer pockets, and a wet/dry pocket for shoes or gym gear. A built-in TSA-approved lock and a hidden pocket are also listed.

The stated carry-on dimensions are 20 × 12 × 7.8 inches, and the listing says the backpack fits most airline carry-on size limits. Airline rules vary, so the claim should not be treated as universal, particularly when the bag is expanded or fully packed. The capacity figures also conflict with the 60L product name, leaving the exact usable volume unclear.

What it works with

Its layout suits clothes, a laptop, and travel accessories in one bag. For example, on a short work trip, you could compress a change of clothes, place a laptop in its padded sleeve, and keep sneakers in the separate wet/dry pocket rather than mixing them with clean items. It is also presented for weekend travel, commuting, gym use, and outdoor trips, though the information does not establish weather protection for the whole backpack.

Compared with a conventional travel backpack, the pump and compression compartment offer a way to reduce clothing bulk, a simpler bag may be easier if you do not need that feature. It suits you if you want separate storage for clothing, a laptop, and shoes. Not the best choice if you need a clearly confirmed capacity or a guaranteed fit under every airline’s carry-on rules.

Usage tips

Pack the compression section with clothing rather than treating the whole bag as a vacuum-sealed space. Use the pump as directed, and leave room for the other compartments if you plan to carry a laptop and shoes as well. The listing notes that the high-density zipper may feel tight at first and recommends holding the bag firmly and unzipping with steady force. That is worth knowing when opening a packed bag in a crowded terminal: avoid yanking the zipper if it resists.

Practical doubts

Does it include the vacuum pump? Yes. The product description lists a pump in the package.

What size laptop does the sleeve fit? It is listed for laptops up to 17.3 inches, no further device dimensions are provided.

Is the whole backpack waterproof? The description specifies a waterproof wet/dry pocket, but does not say that the entire backpack is waterproof.

Is it worth it?

This design makes most sense for travelers who value compressing clothes and separating shoes, work gear, and small essentials in one carry. The pump adds a useful packing option, but also means more steps than simply loading a standard backpack. The unclear 60L versus 35L-to-50L capacity is the main reason to be cautious: if you need a dependable volume figure for a particular trip, this listing does not settle it. Choose it for the compression setup and compartment layout, skip it if exact capacity or assured airline fit matters more than those features.
