Thirty-two liters, a pump in the box, and a price at the bottom of this group — that's the short answer to why the WONHOX is the pack we tell most people to buy. At 18.5 by 12.2 by 8.66 inches it's built for the personal-item slot rather than the overhead bin, so the compression isn't buying you a bigger bag. It's buying you a free one on the airlines that charge for a carry-on.
The valve design is what keeps bringing us back. The little electric pump pulls the air out quickly, but when the battery is flat you can press the air out by hand and close the valve behind it. That second option matters more than it sounds: a compression pack that only works on a charged pump is a pack that stops compressing on day four.
Inside it's the standard travel-pack layout done properly — a padded sleeve that takes a 15.6-inch laptop, zip pockets for cables and a passport, and a shoe compartment at the base. We'd happily trade that shoe compartment for depth in the main bag; a pair of sneakers in there eats the space the vacuum system just won you, so we keep it for sandals and pack shoes flat in the compression section.
At 1.14 kg empty it disappears on your back, and the water-repellent polyester shrugs off the walk from the terminal to the train. It's also the pack here most likely to slide under the seat in front of you without an argument — the sort of thing you appreciate only when the cabin is full and the bins shut ten minutes ago.
Pros
- Priced with the cheapest packs here, pump included
- Personal-item footprint that fits under most seats
- Manual air release when the pump runs flat
- Light 1.14 kg empty
Cons
- Zippers take the strain when packed to the seams
Our pick for most travelers: a personal-item footprint, a pump that still works when the battery doesn't, and a price at the bottom of this group.
