VGCUB Vacuum Backpack 40 L, Flight Approved, Peacock Blue
The VGCUB Vacuum Backpack 40 L is the largest bag shown here, measuring 40 by 30 by 20 centimetres and rated by the manufacturer at three to five days of clothing. A built-in vacuum system recovers more than half the volume of bulky items, and a padded layer takes a laptop up to 15.6 inches.
What this model is built around
Forty litres is the ceiling for a bag that still has to clear a cabin allowance, and this model sits at it deliberately. Above that figure a backpack stops being hand luggage on most carriers, which is why nothing shown here goes higher. Within it, the volume is what makes a season with bulky clothing workable.
Compression is the reason the capacity goes further than the number suggests. A coat, a fleece and a towel are mostly trapped air; sealed and pumped, they give back more than half the space they occupied. That is the difference between three days and five in a cold month, and it is why the 40-litre model rather than the personal-item one is the answer when bulky items have to travel.

Figures are as published by the manufacturer. Cabin and personal-item allowances differ by carrier and change without notice; treat any airline figure here as typical rather than guaranteed.
What it holds, and what it does not
Three to five days of clothing, per the manufacturer, and more of it in winter than an uncompressed 40-litre bag would take. The water-resistant pocket is the detail that earns its place on a real trip: a damp towel or a worn swimsuit goes in there rather than against clean clothes, which is otherwise the standard way to arrive with a bag that smells.
Cabin fit is quoted for both the overhead bin and under the seat, within the limits most carriers publish. Under-seat space is the tighter of the two and varies by aircraft as much as by airline, so treat published figures as typical rather than guaranteed.
Who it suits
Choose it if
Three to five days away with hand luggage only, especially in a season that needs bulky clothing.
Look elsewhere if
Airlines with a strict personal-item box — at 40 litres this is a cabin bag, not a personal item.
Against the other models
This is the one to reach for on a five-day trip, and the wrong one for a strict personal-item allowance: at 40 litres it is a cabin bag. The 18 by 14 by 8 model is the answer there. Against the 30-litre carry-on it trades the flat 180-degree opening for volume and compression.

Vacuum Backpack 40 L FAQ
How many days does the 40-litre model cover?
Three to five days of clothing, per the manufacturer, and the compression is what stretches that when bulky items are involved.
Does it count as a personal item?
No. At 40 litres it is a cabin bag rather than a personal item. The model built to 18 by 14 by 8 inches is the one sized for a strict personal-item allowance.
How much does vacuum compression actually save?
The manufacturer states more than 50 percent on bulky clothing. The saving comes from lofty items - coats, fleeces, towels - and is close to nothing on dense ones.
What is the water-resistant pocket for?
Damp items: a towel, a swimsuit or clothing worn in the rain, kept away from everything else in the bag.
What size laptop fits?
Up to 15.6 inches, in a padded compartment. Larger 17-inch machines are outside what it is built for.
