Being jammed in confined spaces for hours is an unfortunate part of the business for many professionals we serve. Whether it's a military unit in a personnel carrier, a pilot in a cockpit, drivers in a HumVee, or a journalist in the back of a goat truck, they all have to bring their gear, and all may need to 'relocate' in a hurry. This is the environment for which our Evac(TM) line of sling-packs has been developed. Slim shaped, for fast manoeuvering in crowds, they can be stored in vehicles/lockers, and are quick to take on or off. They are also ambidextrous, and unlike others in this class, are actually comfortable to wear. The main padded strap is cocked at either the right or left lower corner, so the pad aligns ergonomically in the correct body-hugging direction. There is no slack, or gapping away from the body as is typical with similar single shoulder packs. The bag can be rotated to the chest for on-the-go access, and all pockets are designed to face the user in this mode on either the right or left side. This means the user can go from wearing the pack on his back, to driving a vehicle with it on his chest in just a few seconds. One-strap also makes shouldering a long-gun natural - unlike a regular backpack.
