Vacuum Backpack 

This collection of vacuum backpack is equipped with a fully detachable airtight vacuum pouch as its core design. The independent airtight bag can be quickly separated from the main backpack shell for separate use, cleaning and storage. Built with air-sealed waterproof seams and one-way air exhaust valve, it supports manual or electric vacuum pumping to squeeze out excess air inside, greatly compressing the volume of contents and eliminating air expansion. The fully sealed air barrier effectively blocks air, moisture, dust, mildew and peculiar odors, keeping stored items dry, fresh and odor-free for long-term transport and storage.
