The other family of three we’re traveling with packed all their luggage in Spacepaks — as a result, they only have half of the take-alongs that we do.
So how to Spacepaks work? The bags feature air-vents that work to remove all excess air from the packs as you add your clothing — similar to vacuum-sealing. Watch the demo below — when packed properly, you can fit up to two weeks worth of clothing, toiletries and even shoes (yes! there’s a Spacepak for shoes that fits two pairs) in a standard carry-on.
