WRAL reporters test vacuum-seal Space Bags with both stuffed animals and clothing. The first bag seals without any problem, but a seam springs a leak after a few minutes, causing the bag to expand. The second bag works better, flattening the contents and remaining sealed. They test out the promise that Space Bags lock out moisture by submerging the second bag in a hot tub, and after a few minutes underwater, the contents were still dry. Space Bags are advertised as being made of nylon, so they're more durable than plastic bags, but the WRAL team found the material to be very thin and susceptible to puncturing. Overall, the WRAL team says that Space Bags could help alleviate some storage issues, but being prone to popped seams and punctures, they may not be worth the cost.
