A week of gear, zero checked bags. The Ultrahauler™ Backpack maxes out international carry-on limits, so everything you need comes with you, no gate-checking or baggage-carousel waiting. It keeps the clean stuff clean and the dirty stuff separate: muddy shoes get their own waterproof-lined pocket, and the MegaMouth exterior pocket swallows sweaty layers and last-minute grabs on the way out the door. Passport and sunnies live up top where you can easily reach them. Land, unpack a daypack (the Revy, if you’ve got it), and go find the trail.

Feature Highlights

Maxed Out Carry-On Capacity

Think of it as a portable closet for a week's worth of gear. It pushes the boundary of international carry-on limits at 42 liters, but maxes out at 50L when you need to haul even more.

For All Forecasts

The integrated rain cover deploys quickly from the back slash pocket and stows easily into its designated mesh divider. An oversized reflective screenprint logo keeps you visible when the conditions turn.

Keep it Separated

A designated, side-access padded laptop sleeve can accommodate multiple devices up to 16”.

Mudroom on the Go

A separate waterproof-lined shoe pocket keeps muddy or wet shoes from dirtying up the rest of your packed gear. Sized to fit two pairs of shoes for sizes below M's 9.5/W's 11, and one pair up to M's 15.

Adapts to the Pursuit

The MegaMouth pocket, an oversized external drop-in, can swallow a wide range of gear: stash a light daypack, down puffer, sweaty clothes, or even a helmet. Reinforced vent holes prevent stink when tossing in those dirty layers or extra shoes.

Check & Stow

The articulated, padded back panel opens to secure the adjustable chest straps for compact packing or checking, and hides a secret passport/AirTag pocket.

Two Halves of a Whole

The clamshell-style opening allows the bag to lie flat when unzipped for intuitive organization, while the equal depth of the two sides ensures you can fit most packing cubes in either volume.

Built to Last

Durable, high-abrasion, and weather-resistant materials are designed to take a beating and clean up easily after travels.

Field Team Says >>

“The only travel bag you'll ever need! Janji thought of everything. Clamshell design allows for multiple compartments on the right and left. Zipper pockets make organization easy and sensible for quick overnight trips in a camper van or a multi-week trip overseas.”

The rare bag that can keep up with all my adventures (and all the sh*t that goes with them!)

After months of training + prepping to summit Mt. Kilimanjaro, I’ve accumulated a LOT of gear ... and I finally found one bag that can handle the training, travel and everything in between. It’s so good, I'm bringing it all the way to Africa with me.

I somehow fit a few days of clothes for two people: two pairs of shoes, laptop + chargers, book, notebook, snacks, water bottle, travel docs AND an entire second daypack inside this thing - with room to spare. 🤯 But the best part might be the absurd number of compartments. Everything has a place instead of disappearing into one giant 42L black hole.

This pack is technical enough to haul gear from home to the trailhead, but sleek enough that I happily carry it to work + around the city. Airport, road trip, trail, coffee shop, Africa - this thing is down for pretty much whatever you're getting into. Pretty sure Janji just solved my four-bag problem. This thing is about to see a LOT of miles. ✈️

One bag for any race, any sport

Overall, an impressive bag that reveals more capacity and function the deeper you get into it. They've thought of everything.

The front pocket is large and expands to fit tons of gear, even a cycling helmet. The straps tuck flat against the back panel so the bag slides through airport security without snagging, and the integrated rain fly keeps everything dry (no one wants wet gear). The clamshell setup keeps your smelly race gear separated from your clean clothes. There's even a padded laptop compartment, though race weekend is probably the one trip where it's smart to leave the laptop at home.

It needs one more thing

Compression straps, go look at the Patagonia black hole 45 MLC and learn.

This bag has been the perfect travel bag- it is

This bag has been the perfect travel bag- it is roomy enough, with enough organization, to keep a week’s worth of clothes, toiletries, and laptops/ipads organized- to also being compact enough for a few nights in the van, when space is at a premium.
It is a really well-made high quality bag, easily adjustable, and fits perfectly on top of a roller bag when you aren’t carrying it on your back.

Perfect for all-things ultra organization!

I'm a big fan of this backpack for all things ultramarathon organization! It's an excellent tool to use when planning for any style of race or adventure. I have found it especially helpful for backyard-style events...Your entire aid station can fit in here!

Key for travel organization!

I used this bag for a three-day, 200-mile running relay, where I was essentially living out of the back of a truck. It kept things really simple and organized even when the exchanges got hectic and everything got covered in dust. If I somehow stayed organized, then this really is the perfect travel bag!

The shoe pouch was such a game changer rather than being part of the other seven people always looking for their shoes for their segments, I could always have mine in the same spot

The only travel bag you'll need.

The only travel bag you'll ever need!

They thought of everything. Clamshell design allows for multiple compartments on the right and left. Zipper pockets for easy and sensible organization for a quick overnight trip in the camper van to a multi-week trip overseas.

I particularly like the stinky shoe pouch on the outside of the bag to keep those stinky shoes away from my clean-ish clothes on the inside.

The shoulder straps are super comfortable and adjustable and when you don't need them, they can be hidden away to make the bag a more standard travel bag.
