Every question.
One place.

Our Pro Series bags are guaranteed airtight for 18 months under normal storage conditions. The Triple-Lock valve mechanism is designed to hold without re-pumping — a feature unique to Hobby-Sparks. Many customers report seals lasting 24+ months, especially when stored away from direct sunlight and sharp objects.

No. Our bags are compatible with all standard household vacuum cleaners — upright, canister, cordless, and handheld models. Every bag ships with a hand pump adapter as well, so if you're packing a suitcase before a flight, no vacuum is needed at all.

For most fabrics: no. Natural fibres (cotton, linen, wool, down) compress and recover without damage. We advise against long-term compression of high-end suits, structured jackets, or delicate knitwear — use our garment bags or closet organizers for those. Always fold, never stuff, to avoid permanent crease marks.
