Yes, it’s Bag Week, where we celebrate all the best bags of the year here at TechCrunch. And there is little more satisfying than finding a basic black one that’s functional, stylish and unique. Luckily, Canadian urban athletic apparel maker RYU makes three such bags, and while each one has its own particular appeal depending on what you’re looking for in a backpack, they’re also all winners that elevate the basic black backpack to new heights.

Quick Pack Lux 18L ($185)

RYU’s “just right” offering for me is the Quick Pack Lux 18L capacity bag that’s pretty much perfect as a general-use day pack in terms of cargo space, and that can also serve well for a one or two-night trip, depending on how lightly you pack.

The RYU’s signature feature, and what makes it my favorite day pack in terms of everyday use around the city, is its profile — a silhouette that is made all the better because RYU uses an internal molded shell to ensure that it never flattens down or loses its shape, regardless of how full or empty the bag actually is. This is actually a huge selling point for me, and one that makes the RYU Quick Pack Lux 18L almost certain to become my go-to daily bag. Inside, there are a few pockets, including a laptop sleeve that can fit up to a 15-inch MacBook Pro — another rarity in a day pack this low-profile.

In addition to the integrated frame, the Quick Pack Lux is kitted out with premium materials, like the leather accent patch on the top flap, leather shoulder straps, an outer layer of poly-cotton blend that covers a wax-treated canvas and nylon interior for water resistance and durability. The materials definitely feel premium, though the outermost layer resembles kind of a yoga pant material, and in my house definitely attracts and picks up my dog’s easily shed white hairs with reckless abandon. I’m more than happy to get out the lint roller once and a while as a trade-off for just how good looking the bag is, however.

It wears slightly long, but tight to the back (for reference when sizing up the photos above, I’m 6’2″ and quite a bit of that is torso). The removable chest strap helps keeps the profile pretty seamless, and there’s a handle on top for easy carrying when not on the back.

Another unique feature of the Quick Pack Lux is that it opens from the front, with the flap at the top unbuckling to reveal two zippers that run the length of the bag. Undo these, and you get basically a duffel-style cargo loading method, which is great for arranging your stuff without having to layer or dig down as you would in a top-loading pack.

Locker Pack Lux 24L ($215)

The Locker Pack Lux 24L is the more spacious version of the Quick Pack Lux, with 6L extra volume for packing your gear. It’s designed more for those overnights or two-day trips, and yet it doesn’t really add that much in the way of bulk if you’re looking for something that can serve flexibly as both day pack and weekender.

The Locker Pack Lux has the same materials combination as the Quick Pack, but is a bit longer and so is probably better suited for taller people. It still offers a very slim profile, and has the same internal structural components, which means it’ll keep its shape, but it has a bit more leeway for expansion, too, letting you pack in a surprising amount of stuff via the front-loading, double zipper stowage and packing flap.

Unlike the Quick Pack Lux, you also get external access to the laptop compartment in the Locker Pack, which gives you an easy way to get at up to a 15-inch notebook. The leather-accented top flap closes down over this compartment, too, to give you some protection against the elements in the case of light showers (RYU also sells a dedicated rain hood separately).

Express Pack 15L ($90)

The Express Pack is the smallest of these RYU backpacks in terms of packing volume, but it’s also probably the best option when it comes to an all-around city day pack that will fit you regardless of height and frame. The extremely minimal aesthetic is great for the city, especially with the polyurethane outer coating that wraps a middle canvas layer for the bag’s body.

This is a very lightweight bag, but the internal pocket can actually fit a lot of stuff when needed, and there’s a single woven pocket on one side of the exterior for stowing a water bottle. This adds an asymmetrical look, which is also pretty cool looking. Inside, there’s a zippered mesh block and a fully zippered front pocket for separating your sweaty gym gear, plus a laptop compartment that can fit a full, 15-inch MacBook Pro without issue.

The bag is comfortable to wear, but doesn’t have the internal structure of the other two, so if it’s empty it’ll hug a lot closer to the body. If there’s one thing I’d change about it, it’s the RYU branding — but it does actually recede to being barely visible in less direct lighting, and is more subtle overall than it looks here.

Overall, RYU’s bag lineup is impressive, and offers something for everyone. The Vancouver-based company has done a great job of delivering highly functional designs that also offer great style with pretty much universal appeal. The company also offers non-Lux versions of both the Quick Pack and the Locker Pack, which drop the leather accents and embedded waxed canvas, but which also offer some decent discounts if the prices above strike you as too high.
