STX- STX also makes an excellent line of equipment.  This includes the Shogun Shoulder Pad.  These sport a super-soft liner that feels comfortable while running.  STX also includes rib pads in their lineup.  This includes the new Rival Rib Pads.  This pad specifically protects the hips, ribs, and spine on the lower half of your torso.

Warrior- Warrior makes light-weight, durable pads players of all ages can wear.  These come with a flexible hinge design for less restriction of motion.  Warrior also has an air flow comfort system.  This allows superior air flow through the pads.  The pads are constantly being upgraded to become lighter.  Plastic shoulder caps give you ultimate shoulder protection from attacking opponents.

Gait- Gait equipment is probably the least protective but is still also the lightest.  Some of these pads include the Chaos Liner, which is the least amount of coverage possible, and Insanity Shoulder Pads.  The Insanity Shoulder Pads include a removable rib belt and the whole package is actually 6 pads in one.  The Chaos Liner is coincidentally of a new design called the V-Zone chest pad.

Brine- Brine has a sweet collection of equipment.  This equipment line includes the Element Shoulder Pad, the Spartan Core, the Spartan Shoulder Pad, and the new Matrix Shoulder Pad.  The new Matrix Shoulder Pad includes an internal plate system in high impact zones.  The Element Shoulder Pad has a wrap-around protection advantage which is just like wearing a rib protector.  The Spartan Core covers only the shoulders and chest area.
