Achieving maximum volume reduction without damaging clothing requires deliberate staging. Tossing random garments into the sack produces hard, lumpy masses that will not sit flush inside a suitcase shell.
Start by folding garments into uniform rectangles that match the footprint of the bag. Lay heavy denim and knitwear at the base, keeping delicate items or collared shirts near the center. Leave at least two inches of clearance below the zipper line; overfilling forces the seal apart under pressure. Run the provided zip slider across the track twice, pressing firmly along the entire edge to confirm full engagement.
Uncap the deflation valve, align the electric mini pump nozzle, and power it on. As the pump draws out air, use flat palms to guide the compressing garments evenly across the base of the bag. This prevents the pack from curling into an awkward cylinder. Once suction stalls, detach the pump, immediately secure the valve cap, and slot the flat package horizontally into your luggage.
