Air comes out and STAYS out!
Set name: 10 Medium
I’ve tried so many different versions of these vacuum storage bags over the years, and this company seems to have finally figured it out. They’re absolutely not exaggerating about the 80% space savings. What really impressed me is the pump design — it actually screws onto the bag, so it stays securely attached while removing the air instead of constantly slipping off. It also has a stop valve built in, which prevents air from escaping when you remove the pump to put the cap back on. Such a smart design improvement over other brands I’ve used.
I bought the medium 10-pack to store my winter clothes in two 66-quart storage bins, and they fit surprisingly well. That said, part of me wishes I had also picked up a few of the smaller sizes just because they’d probably make stacking and organizing even easier. Overall though, I’m really impressed with the quality and design.

Great bags!
Set name: 10 Jumbo
These space bags are awesome! The company gives you a hand pump but your vacuum works great. They also give you tabs to slide over the ziplock part which works great. I bought the jumbo bags and I can’t believe what I was able to fit in them. More than one summer king size comforter in a bag, and 1 oversized extra large and thick king size winter comforter with shams and sheets in one bag. Other bags had several queen size quilts or comforters and decorative pillows. I highly recommend these bags. The price is great too.

Space saver for travel
Set name: 20 Combo
So far the bags are working out just fine. There was one bag that does not seal, but I will still use it for storage . They will definitely help save room in my suitcase because I have to transport bulky clothing. It is very easy to pack and seal the bags and I like the variety of sizes.

Great Bags!
Set name: 20 Combo
The bags are perfect for packing clothes for storage. I used them for my babies clothes and they fit great. I love the variety of sizes, and they are very easy to use. The zipper piece is a bit tricky to get on, but the zipper stays locked in place when closed.

Saves space and keeps moisture and bugs out
Set name: 20 Combo
I have never bought these bags before. I went with good reviews. I used to pack my extra curtains in them. I definitely saved a lot of space. I tried using the hand pump, works fine just more effort and time on my part. The sweeper works fast and great.
These are awesome bags. Ordered another box.
