DESCRIPTION
If a chest rig works well in the front, but lacks storage space in the back, the TT Modular Chest Rig Pack is exactly the right solution. It expands the carrying platform with a slim, close-fitting pack featuring three front pockets, a main compartment, and preparation for a hydration system. The volume is variable, allowing you to keep the pack flat when carrying less, or expand it up to 20 liters when needed. Important: It is designed as a system component and should not be confused with a classic hiking backpack.
This IRR version uses coordinated materials and components with defined reflection properties in the near-infrared range. This does not change the basic function of the product, but it is a relevant difference from the standard color version. If you do not specifically require this feature, you can choose based on fit, construction, and color. It is particularly useful when combined with the TT Modular Chest Rig 4xM4, for which this back section was designed.
What is the TT Modular Chest Rig Pack suitable for?
- Expansion of a chest rig: for additional storage space on the back without a separate large backpack.
- Hydration and light extra clothing: Hydration system preparation and variable volume make the pack practical for longer training days.
- Standalone use: the back section can also be worn separately using the included shoulder straps.
- Modular platforms: Adapters for attachment to compatible carrying systems are provided.
Design and practical use: What can the system do?
- Variable volume 12–20 liters: can be adjusted to the actual contents.
- Slim main compartment: keeps the depth on the back relatively low.
- Three zippered front pockets: two with approx. 1.5 liters and one with approx. 1 liter volume.
- Hydration system preparation: for compatible hydration bladders and hose routing.
- Two zippered interior pockets: for smaller items and better organization.
- Daisy chain and name hook-and-loop: additional attachment and identification options.
- System adapters included: for the intended chest rig/carrying platform configurations.
Back sections attached directly to the carrying system sit very close to the body and distribute the load differently than a normal backpack. This is compact, but also means that you cannot easily reach the contents on your back yourself. Therefore, plan to keep frequently needed items in the front or on the sides and use the back section for gear that does not need to be accessed constantly. Also, after loading, check whether the back section pushes upward when sitting or wearing additional outerwear and whether all side connections are tensioned evenly.
Terms explained simply
- Daisy chain: a row of attachment loops for light additional items. It is not a complete replacement for MOLLE.
- Hydration-compatible: means that a hydration bladder and hose routing are provided; the hydration bladder itself is usually not included.
- Back section: a module that can be connected directly to a front carrying platform and therefore does not require classic backpack straps.
- SAPI size M: standardized shape size for a plate insert; a protective plate is not included in the delivery.
Selection note: Is this product suitable for your setup?
The Modular Chest Rig Pack is especially worth it if you already own a compatible TT carrying system or deliberately want to build a system consisting of a front and back section. For normal hiking or EDC, a standalone backpack is usually less complicated because it is easier to put on and take off. Also, plan for access: A back section attached directly to the rig is very close to the body, but cannot be reached as quickly as a shoulder bag without assistance.
