Was so impressed with the quality of the 3 piece set and the 2 piece starter set, we ordered 2 more of these individual bags for our carry-ons. Love these bags!

Absolutely Worth the Money

I first took this Spacepak to a two week trip through New York, Boston, and Philadelphia. It really is worth the money when it comes to keeping you organized and clean. What separates most Spacepaks from other packing aids is the double sided laundry/clean feature that completely solves the problem of packing your suitcase and keeping your clean clothes apart from your laundry when you have to pack for a trip through multiple destinations like I have. I especially love the Underwear Spacepak because I'm very particular with keeping my undergarments separate from the rest of my clothes. The only qualm is that a Spacepak may not be compatible with every suitcase, I suggest you take measurements to make sure it works for you.

I bought the Yellow (Underwear) , Blue (Clothes) and Purple (Lingerie) a while ago.
I remember looking on the website and really going back and forward for weeks. (It is kind of an investment, am I right?!) Then I saw them "in real life" in a little travelshop near me and bought them instantly!
Let me say I have not regretted it for one single second.
Before I had those mesh-type kind of luggage deviders. The Spacepack is a little bit more heavier, but are soooooo much better thanks to the "laundry side" of the pack (and the handle).
You do not lose any space due to your laundry. Just throw the used clothes in there and since they'll be in the same bag as you packed them, it's lots easier to have an overview of all your stuff.
When I return back home, I know precisely what I used and... what I didn't use! Every trip I take, my packing gets better and lighter. (Learning curve!)
Recently, my boyfriend and I took a 10-day long vacation. Normally I would have thought to need 2 big suitcases to check-in (with probably an extra carry-on)... Now, he used 1 blue and 1 yellow pack. I used 1 blue, 1 yellow and 1 purple pack. As simple as that! We could of have fitted in 2 cary-ons, but we used one check-in suitcase and one carry-on (to have some place for souvenirs).

Size wise, I'm in looove with the yellow pack. If you only can get one pack, believe me: you got to go YELLOW ! In my experience, it's the most handy size. It's perfect for a weekend or overnight stay. All of my clothes fit and I keep a lot of space in your carry-on for my beautycase, my shoes,... ! (Since it's for 2 to 3 days, I really don't mind that my underwear is mixed with my clothes.)
And if you leave for an extended trip, you could easily get away by using 2 yellow packs :)

Flight changing!

I love this little pack! Bought it on a whim just before I set off for a three month trip with a backpack. This fit inside my backpack perfectly and allowed me to take about two week's worth of clothes and undies with me. I've since taken it on countless other trips overseas and domestically.

Useful for preventing messes.

Really does make the suitcase more manageable

Used this on a one-day trip. It really is a lot easier being able to just lift the bag of clothes out of the suitcase rather than rummaging around in my carry on looking for stuff. This is a nice size for a carry on bag.

Not just for undies!

Review by Brenna

It's a shame the spacepak series is labeled for specific use — the underwear pak with the underwear illustrations, clean/dirty and so on... I use the undie pak as the main pak in my carryon. I roll up tops and undies in the one side, pants and rolled up sock on the other. Such a space saver, it's all I ever use! I had more than enough to wear on a 12-day trip to two climates, three foreign countries, all in my carryon!

Very Useful

This kept all my first layers, undies and pj's in one handy place, and separate from all my day wear clothing, so if I needed an item, I didn't have to dig for it in the other spacepak or loose in luggage. Love the clean/laundry divider, especially for stinky socks!

perfect for small bags

This is the perfect size for packing a ton of shirts and shorts into my duffel bag (breaking the rules, I know!) This really helps to maximize space.

I love all of the spacepak items. It makes packing and unpacking so much less overwhelming and actually kind of enjoyable since everything is so organized and easy to manage.

Great product!

I love my Spacepaks! The quality of the bags is top notch. The idea of clean & laundry sides is ingenious (especially for the underwear & socks).

I have used mesh style packing cubes for travel for years and they keep all my clothes so nice, wrinkle-free and compact. This cube is quite large so I used it for shirts and sweaters and a smaller one for undergarments. I do like the separation between dirty and clean as you travel but I do like my previous cubes that are mesh as you can see the clothing. The colors of these cubes are cute. They are very useful to organize clothing. <akes it easy to unpack the suitcase as I leave the clothing in the cube and easy to repack as everything just needs to be zipped up. All about organization. Highly recommend!

Best Travel Companion

I have several spacepak compression bags and I never travel without them. The are easy to care for and provide the best organization for clean to dirty clothes. I often travel for scuba diving and these are great to pack up damp items when in a rush to get to the next destination and keep them separate from you clean and dry clothes. Also the different colors and patterns are good to identify what is mine versus my husbands.

Love it!

I love the underwear spacepak - it holds so many pair of underwear, undershirts, tank tops, bras, socks, etc... and keeps the clean ones separate, and organized!

Great Item!

This was a perfect product for a recent 14 day vacation, with a lot of changes in hotels and moving around, for keeping track of both clean and dirty items. Just purchased one for my husband for our next long trip!

Great invention

I haven't used my undergarment bag yet, but I know how wonderfully well my other spacepac works. All of my shirts and tops came out of my pac without a wrinkle on a recent trip to Europe. Unbelievable. I've recommended them to my friends. They love them as well.
