Travel bags
Size: 12 Combo Travel Size
Perfect packing bags. I’m using them for a trip to Alaska. The pump works easily . I tested them out and the air retention is perfect.? They are not too thick and will not take up space. The material seems like it will hold up without ripping. I will be using them often. They come in different sizes which work perfectly with different items.

These are a travel must!
Size: 15 Combo Travel Size
We recently took a trip to Japan and South Korea with our 3 kids, and needed to bring all their clothes for 2 weeks, with as few suitcases as possible.
These bags were a life saver!
We were able to fit so much more stuff in our suitcases with these bags. I don’t know how we would have brought everything without them. We would have had to bring at least one, probably two suitcases more.
Easy to use - the vacuum is compact so you can bring it with you, but super powerful and works quickly. Remember to charge it after you use it for when you pack back up. But, you can manually push out the air as well if you’re in a pinch.

More pros than cons, very convenient, but durability is an issue.
Size: 15 Combo Travel Size
Pros: I think that this is a good product. I've had it for several weeks and travel every week for work. It's a good design and the vacuum pump is ergonomic and reliable, in my experience. Charges relatively quickly at home and I'm not sure how long the charge lasts, because it's convenient with a USB-C port, so I charged whenever the charge got to 3 bars. My experience is that dress shirts maintain the pressing if folded and packed neatly. They're creased, but hang them in the hotel bathroom and the steam from a shower loosens the wrinkles nicely.
Cons: durability. The bags are pretty thin and after 3 or 4 trips the seal in the bag(s) can become compromised. I suspect the leaks are tiny and in the actual bag vs. the seal. With regular use, this was in only two of the fifteen bags. The double zip lock is really durable.
FOR CAMPING: they were great for motorcycle camping, however the durability became an issue. I was camping along a lake and took some care with the bags, but admittedly was a little harder on them than I could have been. I took extra bags just in case, and am glad I did. Three of the 6 bags I took slowly lost the vacuum. If you're using them for camping, pack extras. They're inexpensive enough to continue to buy replacements periodically and you do get a lot.
TIPS: pack the vacuum in the suitcase with the bags. Pack the bags with a complete outfit for each day. The temptation is to pack shirts in one bag, socks/underwear in the other, etc. It's more difficult to repack dirty clothes that way, but if you have each day in its own bag you just use each one for a dirty laundry bag.

Over packer approved! GOODBYE checked bag fees!!
Size: 9 Combo Travel Size
These were incredible for our recent flight to Tampa. I’m an overpacker by nature, and we normally have to check at least one bag, but these completely changed that. We were able to fit everything into our carry-ons and backpacks with room to spare, which even saved us from paying a checked bag fee.
The vacuum came already charged, and I still haven’t needed to recharge it, which was a nice bonus. It also comes with a small travel bag to keep the charging cord together, which made it easy to stay organized. The suction is strong and works quickly. I packed one bag completely full and it compressed it down to about half the size.
The bags are durable and easy to seal, even without using the plastic zipper clips. As long as they’re fully sealed, they stay compressed and don’t slowly let air back in. We unpacked everything at the hotel and stored the empty bags in our suitcases, then reused them to pack for the trip home with no issues.
The vacuum isn’t silent, but it’s not overly loud either. I’d compare it to being quieter than a typical hair dryer.
This is such a game changer for travel and saving space. I’ll definitely be using these for every trip.

Extremely well made travel vacuum bags
Size: 9 Combo Travel Size
These are great kits for Travel and storage.
I now have two sets.
The pump works very well. Small enough for carry on.
One very small dislike, There are small clips that slide across the top closer. But nothing to stop them either end. So may fall off.
But I would highly recommend them. 9 out of 10 for me.
