Sock orphans are particularly inconvenient in a foreign land. Spacepak Underwear keeps pairs together and unmentionables out of sight at security checkpoints in one tidy valise, with dual front-and-back zippered compartments to keep clean undies away from dirty laundry. Overpackers, rejoice! Garments packed flat undergo double compression, allowing for maximum wardrobe options. Learn more about Spacepak

Features and Benefits:

  • Holds up to 13 pairs of socks and 13 underpants (depending on which style you prefer, of course) 
  • Two sets of one-way metal rivets allow for air compression
  • Weighs 13 ounces

Useful for preventing messes. (Posted on 8/1/2015)
Really does make the suitcase more manageable
Review by JanetB
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. (Posted on 12/17/2014)
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! (Posted on 10/2/2014)
Very Useful
Review by JA
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! (Posted on 1/7/2014)
perfect for small bags
Review by hella alyshia
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. (Posted on 12/30/2013)
A Travel Must
Review by Roxy
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. (Posted on 12/28/2013)
Great product!
Review by PY
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). (Posted on 11/19/2013)
