Adjustable Torso Height - The X40 features three height options with a vertical adjustment range of approximately 9 cm. This means that the same backpack is suitable for smaller or larger male or female torso sizes, ensuring a customized fit for everyone. Individuals with a larger or broader torso can add a booster kit to extend the fit of the backpack.

Core Unit Modular Camera Insert System - The X40 utilizes the DSLR Core Unit System. Core Units provide shock-resistant protection for mirrorless and DSLR cameras as well as lenses, ensuring that the user never carries more padding and weight than necessary. The X40 v2 can accommodate small, medium, and large DSLR sizes. It can also fit flatter mirrorless models.

Two Laptop/Tablet Sleeves - The padded sleeves on the back and front are suitable for laptops up to 16 inches in size. With two sleeves, you can pack both a tablet and a laptop, providing options for different packing scenarios.

Expandable Roll-Top Access - The Action X series is equipped with a roll-top access feature, allowing the bag to be adjusted to your gear needs while maintaining a snug and compact fit. The roll-top can be expanded by an additional 7 liters. The top also includes an extra YKK SplashGuard zipper for quick access, making it extremely fast and easy to reach your gear, especially in bad weather.

Hidden Tracking Device Sleeve - A hidden sleeve for a personal tracking device, so you always know where your backpack is. Should your backpack ever get lost, a tracker can help locate it and recover your gear. The sleeve is compatible with AirTag and Tile Pro devices.
