A 50L Tactical Pack Built Around Function
The Op's 50L is designed around practical carrying capacity, load support and modular organisation. It is suited to people who need more from a backpack than a basic daypack can provide.
50L Capacity
Generous storage for equipment, clothing, tools and supplies without moving into the size of a full expedition rucksack.
Structured Carry System
The Bio-form air mesh harness, internal aluminium stay, padded hip belt and sternum strap provide support when carrying heavier loads.
Modular MOLLE System
MOLLE-compatible webbing allows compatible pouches and accessories to be attached and the pack configured around your equipment.
Hydration Compatible
The pack is designed to accommodate a 2L or 3L hydration reservoir, making it practical for extended outdoor activities.
Designed to Carry Heavier Loads Comfortably

Bio-form Air Mesh Harness
A 50L pack is capable of carrying considerably more equipment than a typical daypack, so the carrying system matters. The Op's 50L uses a Bio-form air mesh harness with an internal aluminium stay to provide structure and support.
A padded adjustable hip belt and sternum strap help distribute the load and keep the pack stable while you're moving.
This makes the Op's 50L a practical option for extended hikes, field work and outdoor activities where carrying comfort becomes increasingly important as the load increases.
50L of Capacity with Practical Organisation
The Op's 50L combines a generous main capacity with multiple storage areas, helping keep frequently used equipment accessible rather than buried at the bottom of the pack.
Front Organiser Panel
Provides a dedicated area for smaller items and equipment that you want to keep organised and easy to access.
External Storage
External storage areas provide additional space for equipment that needs to remain accessible while you're on the move.
MOLLE Webbing
The MOLLE system provides attachment points for compatible pouches and accessories, allowing you to configure the pack around your requirements.
Velcro ID Panels
Velcro ID areas provide a practical location for identification labels, name patches or other compatible patches.
Hydration Ready for Extended Outdoor Use
Staying hydrated becomes increasingly important during long hikes, field work and extended outdoor activities.
The Op's 50L is compatible with 2L and 3L hydration reservoirs, allowing you to carry your water supply inside the pack and drink while moving.
Pair the pack with a Caribee hydration reservoir for a practical hands-free hydration setup.

Hiking & Outdoor Adventure

MOLLE webbing, Velcro ID panels and the structured harness make the pack particularly suited to users who value modular organisation and tactical styling.
