Rework Gear Toshi Sling V2 (2.5L) Review

We’ve tested other sizes in the Toshi Sling V2 lineup and have consistently come away impressed, so we were curious to see how the smallest version stacks up. At 2.5 liters, this is firmly in minimalist territory, but it doesn’t feel like a stripped-down afterthought. Instead, it carries over much of what we liked from the larger models to a tighter, more compact package.

This is a true essentials-only sling. Phone, wallet, keys, maybe a small book or compact tech—it’s all fair game. The question is whether that smaller footprint sacrifices usability or comfort. After testing, it’s clear that while it makes a few compromises, the overall experience still feels very much in line with the rest of the series.

External Components

The exterior is made of 840D nylon and strikes a nice balance between durability and aesthetics. It feels tough enough for daily use without looking overly rugged, and it holds its shape well for a sling this size.

You’re getting YKK zippers throughout, which is exactly what we want to see. They’re smooth, reliable, and feel appropriately sized for the compartments. The Hypalon pulls add a bit of grip and are easy to use, even in less-than-ideal weather conditions.

Woojin hardware is used across the board, and it performs as expected. It’s dependable, low-profile, and doesn’t get in the way. No complaints here.

There are small side loops on either end of the sling. They’re pretty tight, so attaching gear takes a bit of effort, but it’s doable. You can clip on something like a Bluetooth speaker or carabiner if needed, though we imagine most people will leave these unused.

One of the more interesting features is the bottom compression strap system. When not in use, the straps tuck neatly behind a magnetic flap, keeping the sling looking clean and streamlined. When deployed, you can secure extra gear externally. It’s a feature we appreciated on larger versions, and while it’s a bit more niche here, we still dig having the option. We used the system to attach a mini travel tripod.

Up top, there’s a simple carry handle. There’s no padding or aeration, but it blends in nicely and doesn’t snag on anything. It’s not flashy, but it gets the job done when you need to grab the sling quickly.

Fit Notes

The back panel has no padding, which might sound like a downside, but given the sling’s small size, it’s not a huge issue. That said, there is a semi-hidden back pocket built into this panel, so what you store there matters. Stick to flat items—anything bulky will press into your body and become noticeable.

The strap also skips padding and aeration, but it’s fairly wide, which helps distribute weight better than you might expect. Since you’re not likely to overload a 2.5L sling, comfort holds up reasonably well during testing.

One smart design choice is the placement of the buckle near the sling body. This makes it much more comfortable to wear with a backpack, as you’re not dealing with a bulky buckle digging into your back or shoulder. It’s a small detail, but one that makes a difference when paired with larger travel gear.

Inside The Sling

The interior features a 210D PFAS-free PU-coated ripstop nylon lining that feels durable and easy to work with. It’s lightweight but not flimsy, and it helps maintain the sling’s overall structure.

There’s a semi-hidden pocket that runs the length of the back panel. It’s fairly large for a sling this size and works well for flat items like a phone or a small book. Just keep in mind that you may feel anything bulky when wearing the sling.

The front pocket takes up most of the sling’s footprint and offers a good amount of depth. There’s no built-in organization here, so it’s more of a dump pocket, but that works fine for quick-access items. There’s also a small loop inside where you can attach the modular key leash.

Up top, there’s a long, narrow pocket that’s perfect for sunglasses, pens, pencils, or cables. It’s a natural fit for those longer, skinnier items you don’t want floating around elsewhere.

The main compartment is where most of the organization lives. On the front side, there’s a dedicated tracker pocket, which is a nice addition if you’re using something like an AirTag. It can also double as a spot for other small items.

Along the back wall, there’s a larger sleeve that fits something like an iPad Mini, a phone, or a small book. It adds a bit of structure and separation without taking up too much space.

You’ll also find four stretchy mesh pockets—two medium and two small. The smaller ones are especially useful for items like credit cards or an ID, while the larger ones handle everyday carry gear like travel earbuds or cables.

There’s a small loop inside the main compartment as well, where the included key leash was attached when we got the sling. We ended up moving it to the front pocket for easier access, but either placement works. Where you put it just depends on your preference.

Overall, the internal layout feels well thought out for the size. You’re getting a surprising amount of organization without it feeling cramped, though the limited capacity means you’ll still need to be intentional about what you carry.
