Hydration Glossary:

Hydration:
The process of adding water or fluids to the body in order to maintain or reestablish correct fluid balance.

Bite Valve:
This is the part of a hydration system that delivers fluids directly to the user's mouth. The valve is sealed until the user bites down on it.

Semi-Rigid:
On backpack hydration systems, the overall shape conforms to your back to create a lightweight, internal "frame". Also, this construction helps to keep the contents from shifting.
 
LIQUIFUSION:
Brand name for our new Personal Hydration System.
 
Reservoir:
Fluid container of a hydration system.
 
Molle:
Stands for Modular Lightweight Load Carrying Equipment. A load-carrying system that's modular, durable, comfortable, and fully integrated. It consists of a butt pack, a main ruck with sustainment pouches and sleeping bag compartment attached to an external frame. There is also a patrol pack, which can be used separately or combined with the main ruck for added load carrying capability. MOLLE can be configured in several different variations to fit the load handling needs of the mission. A connecting device on the vest is designed so that the external frame of the main ruck attaches to the waist belt of the vest to transfer the load from the shoulders and back to the hips where it can be carried much easier with less fatigue.
 
Ergonomic:
Creating products that work with the structure, contours and natural grip of the human hand.
 
Flame Retardant:
Type of fabric that resists igniting when exposed to an open flame. The fabric may still catch on fire and will burn/melt, simply won't ignite with an open flame nearby.
 
Polyester:
Type of man made fiber used in many outdoor soft good products due its excellent performance characteristics.
 
Cargo capacity:
Total amount of space a pack can hold of your gear (expressed in cubic inches or liters).

Quiet, water resistant fabric:
Low noise fabric that withstands water penetration (like rain) for up to several hours. Not meant to be completely water tight or submerged.
