18L Waterproof Packable Backpack
BUILT FOR THIS
Sideways sleet in Iceland. Dusty canyon trails in Utah. The 18L Waterproof Packable Backpack was built to keep your gear dry and your trip dialed, no matter where you land or what the day throws at you.
With sealed seams and a rolltop closure, it earns its keep — then disappears into its own pocket until you call it up again.
see you out there
This bag is amazing. It folds up so small and is the perfect size when in use. We used it to explore Greece and hike all over Crete
Several people borrowed this bag on my scuba trip to the Philippines!! And everyone loved it! Perfect for a day trip out on the boat. Kept towels and clean clothes dry!!
This is a sweet upgrade from my previous packable waterproof backpack. It is very well-designed, and I like that it is made without PFAs. Can't wait to see how it holds up!
This bag is awesome. Very well made
This is a very clever pack. There are many thoughtful design details that show this is the product of many waves of experimentation and real experience traveling. For example the clip straps that allow you to secure tracking poles to the sides of the pack, but there are also little loops where you can clip a water bottle with a carabiner onto it. There’s the small zippered pouch for quick access on the outside of the pack. There’s the welded zipper that help helps improve waterproofing. Love this pack!
This small packable backpack has lots of room! I do like the rolltop closure, as it is very easy to place belongings inside of it. The straps are very comfortable and have great support. I do hikes and in-city walking, so the water bottle pockets are a great addition to this backpack. Folding the backpack can be a little difficult at first. I began to fold the bag into the incorrect pocket at first. This takes some getting used to. I'm excited to use this bag for some upcoming journeys.
I love the quality and function of this bag. It's compact and light. It opens up to a great size that can hold everything you need. Not to mention, it is waterproof! So it's great for our outdoor adventures. Either it's hiking in light rain, or strapping it on your paddleboard, this bag is perfect for your adventures!
I recently took this backpack on a trip through the Faroe Islands and Norway, so it got plenty of use in wet and unpredictable weather. It held up incredibly well and kept everything protected the entire trip. I also love how easily it packs down into such a small pouch, making it really effortless to bring along without taking up much space. I'll definitely be taking on every trip from now on.
The waterproof version is one of the products I’m most excited about in the new lineup. The Garnet color looks incredible, and the waterproof roll-top design makes it feel like the perfect bag for unpredictable weather and outdoor adventures. I can’t wait to put it through its paces on future trips and filming days.
The perfect travel daypack! This bag packs down SO tiny and has been a great addition for when i'm trying to save space when travelling, but still need some sort of hiking pack. Can use it for hiking or just walking around town and don't have to worry about the weather... because it's waterproof!!
Super light, easy to throw in my luggage, and great for day trip adventures. I roll it up and keep it in my daypack and it's come in handy as a personal item or if I overpack at the airport and need an extra way to carry my stuff!

What is the difference between this pack and the standard 18L Packable
Backpack?
The Waterproof version uses sealed seams and a rolltop closure to create a fully waterproof main compartment. The standard version has a conventional zippered opening that is faster to access but weatherproof rather than fully waterproof.

The Matador® 18L Waterproof Packable Backpack is a stowable travel daypack designed for wet-weather trips, urban exploration, and lightweight outdoor excursions. Its 18-liter capacity carries the essentials for a full day, then the backpack packs into its own pocket for compact storage inside larger luggage. It is also sized to meet personal-item requirements on most flights, although limits vary by airline.
The waterproof main compartment combines sealed seams with a rolltop closure to help keep clothing, electronics, and other gear dry during sustained rain. An external zippered pocket provides quick access to smaller essentials, while dual bottle pockets, a high-visibility interior, side compression straps, and a removable sternum strap support practical organization and load stability. Structured LiteCush™ shoulder straps combine padding and breathability with a construction that remains packable. Lockable zipper security loops add theft deterrence, and reflective paracord improves visibility in low-light conditions. Made with 100D recycled nylon that meets Bluesign® criteria, this pack is well suited to travelers who need dependable waterproof storage without carrying a conventional full-size backpack between uses.
