From Tethrd:

Not only does the Ultralock revolutionize comfort in a saddle, but our new oversized Ultralock Haulers with integrated skeleton frame make frustrating gear access a thing of the past. Finally, our new bomb proof yoke system means you can load up your Ultralock and not worry about keeping it in place.

The biggest complaint with pleated saddles is the inability to close the pleat while in transport mode moving to and from your hunting area. They tend to open at the wrong time and flop around. Pleated saddles all suffer from this issue and can lead to an annoying user experience. We re-engineered the concept and created an Expandable Saddle Body to work hand-in-hand with our Ultralock Link system to solve this issue. Our Expandable Saddle Body allows the saddle to move with you while walking, climbing, and hunting. The Ultralock Links are removable, adjustable, and user replaceable. 

With IFS, gear management becomes so much easier. Ultralock Haulers work like a dream by providing an incredibly simple one-handed operation. We also made the Ultralock haulers plenty big for those who like to carry lots of gear. We doubled the volume compared to our original SYS Haulers, while reducing the exterior profile to make the Ultralock even more sleek. They
