The Rhake Weatherproof Laptop Backpack from Mission Workshop entered my life during one of the wettest weeks in months, so of course I subjected the 22-liter rolltop bag to a trial by flooding. I tossed in my expensive 15-inch MacBook Pro along with our iPad Pro and another MacBook. Beyond that, I stuffed it with my AirPods, my iPhone, my Bose QuietComfort 35s, a jacket, a book, and even a Satechi keyboard. (I was already impressed that it could hold all this junk.)

In this manner I braved a deluge for several blocks toward the train station, armed with nothing besides the Rhake and a trashy umbrella. Half a mile on, I was soaked. Water seeped into uncomfortable crevasses in my jeans. But when I unrolled the Rhake at home, I found everything inside as dry as a Steven Wright routine. So let’s get that out of the way: If you want a bag that lets MacBooks giggle at hurricanes—this is it, chief. The only catch is that sometimes its design interferes with its convenience.

Shake it off

The Rhake can weather a storm, but with its $365 starting price tagRemove non-product link, you’ll want to make sure your bank account can weather a beating before picking one up. It’s worth it in the right circumstances. So weatherproof is the Rhake’s tough 500d nylon fabric, in fact, that you might think it was crafted from the same tarp used for heavy tents. The model I received was actually the $455 Rhake VX model, which is made from even tougher VX-21 ripstop fabric.

Like a big of chips, it crinkles with every move. When water hits it, it sounds like those rain-at-the-campsite relaxation tracks. Much of the bag has two layers of this stuff, and you’ll find it in all the seven compartments, including the deep main cavity. The exceptions are few, but they include the mesh sleeve that lets you slip the Rhake over your luggage’s extendable handles and the padding for the back and shoulder straps.

The straps feature Mission Workshop’s “Archiv” band that let you attach other accessories if you need more space.

The Rhake’s zeal for weatherproofing extends beyond the exterior. Unravel the rolltop (which you can hold in place with either a velcro panel or a hook for speed), and you’ll see the weatherproof fabric reaching to the depths of the cavernous 25-inch main compartment. It’s kind of thin, but I can stuff so many things in here that I sometimes forget what lies at the bottom, and photographers will like Mission Workshop’s $130 “Capsule” for cameras that neatly fits inside this space. And there’s more! Along the back of this hole waits the holies of holies: a zippered 18-5-inch weatherproof compartment hiding within the weatherproof main cavity. If that doesn’t convince you the Rhake takes its mission seriously, then nothing will.

It’s a big “secret” compartment, too: You can put a 15-inch MacBook Pro in here and still have plenty of room left over.

Plenty of other pockets burrow into the Rhake’s sides, but getting stuff out of them can sometimes be a pain. The main exception is the zippered 10 x 10-inch compartment near the top, which has more than enough room to hold sunglasses, AirPods, chargers, and other items I reach for on a daily basis. If you’re planning on using this bag as a daily carry, you’ll likely use this pocket more than any other.

That’s a 9.7-inch iPad, which fits fine in this upper pocket without a case.

The second handiest compartment is a 16-inch laptop sleeve accessible by a zipper running along Rhake’s left side, which nixes the need to unravel the full Rhake to pull out your MacBook. (You’ll also be grateful for this sleeve in TSA queues.) Toward the bottom on the other side you’ll find another 9-inch zipper that looks like it conceals another pocket, but in truth it’s stuffed with a pouch for holding your water bottle. I love this design. It allows for a popular feature without uglifying the Rhake’s hiking-meets-tacticool aesthetic, and it also keeps the pocket from filling with water when it rains.

The least handy pocket looks as though it should rank higher. It’s a zippered slot that runs along the Rhake’s bottom, and it’s a great space for holding power bricks and items of the sort. Problem is, you’d better hope you packed it before you stuffed the main compartment with clothes, books—or a store’s worth of MacBooks, in my case. If you didn’t, the weight of everything else in the bag smushes this compartment, making it challenging to stuff in items later.
