Padded protection for 15” laptop and electronics. Versatile organization for everyday carry (EDC).

The TRIDENT-21™ is a durable and versatile backpack for your everyday carry essentials. Total 21 liters with padded protection for electronics (photo/video cameras, drones, etc.). Thoughtful organization for your daily carry items, the TRIDENT-21 is your on-the-road companion.

You can quickly access the interior from the top or side, and like a sling pack, you can quickly get to your gear by swinging the backpack to your front.

Inside, the high-visibility ripstop nylon interior helps you find things in low-light conditions. A padded main compartment is loop-lined with three adjustable padded dividers to organize and protect your everyday carry items. A padded laptop sleeve holds a 15" laptop/tablet. Total 32 pockets and slots for best organization.


Ergonomic suspension, comfortable carry, hydration support and modular expansion.

With an ergonomic and ventilated air-mesh back panel, padded shoulder straps, and a removable 2" waist strap, you can comfortably carry more gear and heavier loads.

The dual-hydration bladder system (rear pocket plus main compartment) lets you carry up to 5 liters of water at once. The hydration hose can be anchored to the left or right shoulder strap. Also, a collapsible side pocket carries your water bottle.

For external MOLLE expansion, it features low-profile Hypalon MOLLE panels for accessory attachment. For ID/morale patches, a loop-faced MOLLE-Air panel is located at the top and bottom front pockets.


Ultra-durable design with all-weather protection for your everyday adventures & travel.

For the ideal balance of weight and strength, we use ultra-durable CORDURA nylon with DWR (Durable Water Repellent) for exceptional all-weather performance. Premium YKK zippers & ITW/Duraflex hardware all come standard.

The TRIDENT-21 is the most versatile and durable day pack ready to handle any situation you encounter, helping you stay prepared for your everyday adventures.
