shape your trip
A checked bag means a line before your flight, a wait at the carousel after it and a fee each way. Then you drag a suitcase over cobblestones and up hotel stairs.
Stand in line to check a bag
Wait around at baggage claim
Drag a suitcase across the city
Caracol bags are sized for the free personal-item slot, carry like a real backpack and open like a suitcase, so one small bag can cover a long weekend or a week.

What travelers are saying
"We used two Underseat Pros as our only luggage for a month across Spain and Morocco. Not one bag fee, and they carried comfortably all day."
Ines and PaulSample review
"I travel for work most weeks. This rides on my roller, holds my laptop where I can reach it, and goes under the seat every time."
Jonah W.Sample review

FAQ
"I flew Frontier there and back with only this bag. It went into the sizer at the gate without a push. Two compression cubes held everything for ten days, including a pair of sneakers."

Will it fit under the seat?
Our personal items are built to published under-seat limits: the Underseat Pro to 18 x 14 x 8 in and the Underseat 20L to 40 x 30 x 20 cm. Seat space varies by aircraft, so check your airline with our fit checker before you fly.
Is it comfortable to carry?
Every Caracol bag has padded shoulder straps, a mesh back panel and a sternum strap. The Overhead 40L adds a padded hip belt for heavier loads.
How much can I fit?
With two compression cubes, travelers typically pack three to seven days of clothes in the Underseat Pro. Our packing guide shows a five-day list item by item.
