Overview
35L Clamshell Backpack
Open it. See what you need. Sentry is a 35-liter backpack that opens fully to expose the main compartment. Designed to accommodate CORE-01, it gives you straightforward access to organized equipment and the personal essentials packed around it.
Access
Unzip Sentry and fold the front panel away to reveal the interior. The full clamshell opening lets you arrange your gear, check your packing, and reach into the compartment without working down through a narrow top opening. It’s a practical layout for equipment you expect to use and put away throughout the day. Open the bag, reach the area you need, and return items to their places.
Organization
With CORE-01 inside, emergency equipment stays grouped by purpose on its removable panel. Sentry provides access to the compartment; CORE-01 maintains the arrangement of the supplies within it.
The 35-liter capacity gives you room to plan around both emergency equipment and personal gear. Use it for day trips, travel, or keeping supplies ready to carry from home or a vehicle.
Attachments
External PALS webbing provides an attachment grid for compatible MOLLE pouches and accessories. Add external organization where it serves your packing needs, while keeping the main compartment available for larger items.
