Flight 001 Grey 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.
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
