Vacuum Compression Backpack, Carry- Size Travel Backpack with Vacuum System and Pump, Expands to 55L Packing Capacity, Fits 17" Laptop & 6-7 Days of Clothes, Water-Resistant Compression Backpack

Product description Does the vacuum compression really save space? Yes--when you fold clothes neatly and press out excess air first, the vacuum section can noticeably reduce bulk and help you fit in the same carry- footprint. Results vary by fabric (puffy items compress than jeans). Is this backpack carry- compliant for Spirit/Frontier? The backpack is designed around common carry-/personal-item size expectations and compresses slimmer when vacuumed. Airline size rules can vary by route and fare type, so we recommend checking your airline's current limits and packing accordingly. How do I use the manual pump? Is it hard? It's simple: pack the vacuum compartment, close the airtight zipper fully, press out as much air as possible by hand, attach the pump to the valve and pump until the bag feels firm and compact. It usually takes about 40s depending how full it is. Why is the airtight zipper so tight? The zipper is intentionally snug to maintain a vacuum seal and air leakage. Like sealed zippers, it becomes with regular use. Tip: don't overstuff before zipping--zip first, then compress. Will it fit a 17-inch laptop? Yes, it includes a padded laptop compartment designed to fit up to a 17" laptop in brands. If your laptop is extra thick, measure the device size to be safe. From the brand
