Packs Down Very Small

Carry-on space is finite, and every item competes with the one beside it.

Comes Out Wrinkle-Free

Hotel rooms rarely have an iron, and a creased shirt shows in every photo.

Dries Overnight in a Room

Washing in a sink only works if the item is wearable by morning.

Wearable Several Days

Fewer items in the bag means each one has to survive back-to-back wearing.

Does More Than One Job

A layer that works as a pillow, a blanket, or a jacket replaces two packed items.
