Frequently Asked questions (from the seller's page)
Does this bag work for modular packing in a backpack? Yes! Use these bags for all compressible items. First, squeeze the air out, then pack the dry bag into a tight space so it doesn't draw air back in. It works wonders on sleeping bags and insulated clothing.
