REVIEW – Planning for travel can be difficult. Making sure you pack everything, plus making sure that you leave enough room for things you might pick up along the way, can be daunting. We have been on multiple trips where friends we made on the trip ended up buying more luggage to transport their new treasures home. What if there was a way to pack an extra bag – something large enough to carry perhaps 55 liters of additional stuff? But that bag would have to be small enough not to take up any appreciable packing space in your regular luggage. Orbitkey has an answer for that conundrum with the Orbitkey 55L packable duffel. They sent two different colors to check out, plus they thoughtfully sent along an Orbitkey 3L travel sling bag for good measure. Let’s see if these bags can solve some travel problems!

What is it?
The duffel is exactly what the name says – a duffel bag. It has one large interior opening plus a couple of external quick-access pockets. Its secret sauce is that it flips inside-out into one of those pockets, folding up to nearly nothing for stowing in another bag. The travel sling bag is a small bag with a long strap. It is designed to be worn across the body or carried as a pouch. It zips securely and is designed to keep valuables secure against your body. The interior features multiple pockets and tuck areas to organize your daily carry do-dads. To be clear, the travel sling is an extra purchase and does not automatically come with the duffel.

Design and features
Duffel
The duffel arrives folded into itself. Its single pocket doubles as a self-storage pouch.

To understand how small this bag is when folded, I plopped one of my small TV remotes on top for comparison.

The bag is also quite thin when collapsed. You can see that, like most things, you can never repack it as well as it comes from the manufacturer. The black one on the right was repacked by me. The olive one on the left is how it arrived.

Regardless, the bag is still tiny when packed. To use the bag, unzip the zipper and pull the bag out from the pocket.

It unfolds to its full size.

The storage pocket doubles as a small exterior pocket with a water-resistant zipper closure. A second open pocket sits right behind it.

The double top handles snap together with a single snap.

The back has a luggage handle pass-through strap, allowing you to slide this over your suitcase’s handle for easy toting.

Both sides also feature small ribbon-style grab handles.

Everything is sewn together with sturdy thread. The fabric feels tough while still being lightweight and flexible. The zippers are beefy with strong cord pulls.
Duffel bags aren’t known for their pockets and dividers. The Orbitkey 55-liter duffel lives up to that heritage with a single, large opening inside the bag, devoid of pockets and tuck areas.

This isn’t designed to be a primary travel bag. It is an auxiliary bag designed for quick-tote situations, and in that role, it is perfectly suited. When first untucked, the bag is pretty wrinkled. But this isn’t designed to accompany tuxedos and gowns on the red carpet. It is designed to be used when you suddenly need another bag on the road. One thing it doesn’t have is a shoulder strap. That means that if you pack it to its claimed 20kg limit, you’ll be toting that with one hand.
Travel Sling
The travel sling is a small bag designed to be carried either as a pouch or across your body with the included strap.

The back features a single zippered pocket. It is large enough to hold a passport and is RFID-blocking.

It also has a small hand strap that allows you to slide your hand into the strap to hold the bag as a pouch.

The length-adjustable shoulder strap connects to the bag with two custom carabiners.

The loop pulls on the twin top zippers, as well as the exterior pocket zipper, can be locked into the carabiners to effectively lock the sling. With the sling’s zippers locked into the carabiners and the strap securely across your body, this travel sling would be an extremely unattractive target for pickpockets.

The interior is deceptively large. The main compartment would easily swallow a large cell phone.

The interior is divided with thoughtful features on both sides. The front side has a pen loop, a hidden key loop, a zippered pocket, and several elastic mesh pockets.

The back has another RFID-blocking zippered pocket.

The quality materials and construction make this sling bag feel like you could abuse it daily, and it would still be looking good for years.
Performance
Duffel
The duffel performs like a duffel! Toss whatever you want into the cavernous interior, zip it up, and go. We did that for a short overnight trip. Everything my wife and I needed fit inside with room to spare. You could easily carry a pair of shoes, several shirts, a couple of pairs of pants, undergarments, and toiletries, making this an ideal weekend getaway bag. But where this bag really shines is its portability. Here’s a look at the black duffel stuffed full with the olive duffel still folded.

To really get a sense of how small it folds, here is the folded olive bag tucked into the front pocket.

The one thing that is missing is a shoulder strap. This means you’ll be toting this bag with one hand. If you load it up with 20kg of necessities, it will get heavy quickly.
Travel Sling
This was a pleasant surprise. We have been on multiple trips where we wanted to take a few things with us for a long day exploring, but had no practical way to do it. The travel sling gives us a solution where we can carry a cell phone, eye drops, pills, passports, snacks, a pen, room key cards, and other goodies. Being able to wear it close to the body and locking the zipper pulls into the carabiner means our stuff will be secure, even in crowds. Getting the zipper pulls into and out of the carabiner took a little dexterity, but it got easier after several tries.
Final thoughts
There is a lot to like about these two bags from Orbitkey. First, the duffel nearly disappears into your luggage, but when needed, it unfolds into voluminous extra storage. These two will be a permanent addition to our global travel packing list. The travel sling was a pleasant surprise. First, I wasn’t expecting it, so that was a bonus. Second was its thoughtful design with a place to tuck everything you might need for a day out and about. I expect this will be putting on some miles with us as well.
