TT Modular Combat Pack 24 SL – Small backpack with adjustable back system

This article was sponsored by Tasmanian Tiger. A small tactical daypack with excellent organizational features, it stands out for its adjustable back system. Unlike many small backpacks, which often come with a fixed back length, this one offers a customizable fit.

Data

The backpack has a sleek look with its three attached pockets and allows for efficient organization of the contents.

Main Compartment

The main compartment is equipped with a thick zipper that has two sliders. The main compartment can be folded open completely. At the top of the lid, there is a small zippered pocket. It only extends to the seam that is visible on the surface. On the sides, there are small mesh pockets with elastic edges, and toward the back, there are hook-and-loop panels with MOLLE loops for additional attachment options. Inside, you also have access to the compartment for the back plate. At the top, there’s a Velcro strap that allows you to secure a hydration bladder in place. These side slip pockets help prevent items from getting lost in the main compartment of the backpack. They are great for storing small bottles, optics, pens, or other small gear.

External Compartments

The three attached exterior pockets give the backpack its distinctive look. On the outside, there are laser-cut MOLLE slots and vertical webbing, which can also be threaded with shock cord for additional gear attachment or compression options. The upper 2-liter pocket has a familiar layout, seen in other TT backpacks. Toward the back, there are two open slip pockets, a Velcro-closed pocket, and a strip of loop panel for attaching optional pouches, such as one from the Mesh Pocket Set VL. On the opposite side, there’s a zippered mesh pocket for additional storage. In the corners, there are D-rings where you can secure the contents. The middle pocket has a 1-liter volume and features loops on the back, where you can directly hang items. You can also enhance it by threading elastic cord through the loops for added versatility. The lower pocket has a 2-liter capacity and features vertical micro-webbing and two strips of loop panel on the back. Toward the front, there’s a zippered pocket with transparent mesh for easy visibility and organization.

The Y2 Back System

Now, the standout feature of this 24-liter backpack: the highly adjustable Y2 back system. The back is padded with spacer mesh and foam for enhanced comfort and airflow. Inside, there is a removable plastic frame with molded reinforcements for added structure and support. The height adjustment is reminiscent of the adjustment systems found in larger backpacks, allowing for a customized fit and improved comfort. There’s simply a small Velcro flap at the bottom holding the system in place. Both shoulder straps are connected in a reinforced Y-shape. A webbing strap runs from the Y through the shoulder pads to a ladder buckle, and from there, as a load control strap, to another ladder buckle above the back system. This allows for further adjustment of the shoulder strap length and the position of the padding in a different way. When adjusting the system, you can still comfortably use the load control straps to ensure the weight stays close to the body. This provides extra comfort, especially for people with shorter torsos. Even my fairly tall wife finds the backpack more comfortable with this setting compared to the regular Modular Combat Pack. I’m 1.92m tall and adjusted the backpack to the maximum back length. The Y sticks out a bit at the top, but the backpack is still comfortable to wear. However, it’s probably set too long for me. The shoulder straps are equipped with an adjustable chest strap. The quick-release buckles under the arms can be covered with elastic bands and allow for easy removal of the backpack in almost any situation. The shoulder straps come with D-Rings. The dual-adjustable hip belt is made from 40mm webbing and features elastic loops to secure any excess length. The hip fins on the waist belt feature integrated zippered pockets. You can remove the hip fins thanks to the Velcro fasteners. However, the channel in the back system is not continuous, so it only accommodates two-part waist belts.

Further Features

On the top there is a carry handle. Below that is the port for the hydration tube. The side compression straps allow for attaching additional gear or compressing the backpack. The straps are quite long, making them suitable for securing foam sleeping mats or even a tripod. With the black hook buckle and two loops, you can choose whether to keep the zipper inside or outside the compression. If the zipper is included in the strap, the strap serves as a limit to the opening width of the compartment. Or you can remove the straps. However, the female buckle near the back system is securely sewn in place! Additionally, there are laser-cut MOLLE loops on the sides for extra attachment options. The zippers come with paracord pull tabs and metal grommets. Re-threading them can help reduce noise a bit 😉 On the bottom there are no features.

Conclusion

Purpose
This tactical backpack, with a total of 24 liters of storage, is designed as a combat pack and is perfect for carrying extra ammunition, a cleaning kit, a rain jacket, a day’s rations, and other gear. The easily accessible external pockets are also a great feature, making it simple to organize and find items quickly (“It’s in the middle pocket.”). For bushcrafting, the backpack stands out, like almost every other TT pack, with its color, craftsmanship, and rugged construction. I can also see this backpack working well as a bug-out bag. To use it as a medic backpack, however, I find the lack of internal hook-and-loop panels limiting—but TT does have better options for that purpose 😉
In winter, it’s worth noting that the 19-liter main compartment is somewhat limited in space. With items like rain pants, winter and rain jackets, you’ll need to pack carefully to make everything fit.
Back System
The system is not specifically designed for women. However, for those with shorter torsos or smaller individuals, it helps optimize carrying comfort and fit. The compatibility with thick protective vests is supposedly better, but I still need to check that.
Summary
I’ve been using this backpack for months now, primarily for short day trips, and I’ve really come to appreciate the convenient organization. For my wife, the adjustable back system is fantastic, as she finally has a small backpack that fits her and matches my style. This backpack is now our go-to for travel, hiking, and day trips. I have no real complaints. Tasmanian Tiger offers so many different backpacks that there’s something for almost everyone. Similar backpacks to this one include the Modular Combat Pack with 22 liters or the larger Modular Trooper Pack with 55 liters of volume.
