I don’t often get exactly what I was expecting when it comes to testing gear, but it was a little bit different when I received the Hollis STS. Being both a backplate/wing (BPW) diver and knowing that Hollis makes high-quality diving equipment I knew I could expect—and would get—a fun test run.
I’ll give you a brief rundown if you’re not familiar with BPW diving. Like the name implies, the setup comes with a backplate—the two most common being stainless steel and aluminum—and a wing, or internal bladder, encased in a nylon donut shape. These two components are held together by a harness that can either be adjustable or made of a continuous weave.
BPW setups are generally heavier than traditional jacket-style BCDs, making them difficult to travel with. The tradeoff is that you don’t need much, if any, additional weight. For instance, I can dive in a BPW with a steel tank and a 5mm wetsuit and I don’t need any additional lead.
Another benefit of diving with a BPW is greatly improved trim, as the entire setup is on your back. Thus, you don’t have any bulky pockets or a side bladder encumbering your movements. You also develop better buoyancy control, since all the air is directly behind you. There is no trapped air stuck at your sides.
When it came to testing, the STS performed exactly as I imagined. I maintained great trim and great buoyancy control. The Hollis power inflator made it easy to inject the exact amount of air that I needed into my wing. And not only did the STS perform great, it was comfortable as well.
Some, but not all, backplates are just stainless steel with wing nuts jabbing you in the back, but with the STS you don’t have to worry about that. It comes with lower and upper back pads that keep the hard metal from digging in, which means your time out of the water is just as comfortable as time in the water.
The wing has 35 pounds of lift, so it’s beefy enough to keep you secure at the surface, even with a steel tank. That does make the wing a little wider than its competitors, but this is a small complaint.
I absolutely loved the numerous D-rings for attaching gear to my specific configuration. Four of the eight come pre-bent, meaning no awkward twisting to clip gear on. And two of the eight are attached to the crotch strap, which is a great place to clip on my wet notes.
I had a blast testing the Hollis STS, and I think it’s a great setup for anybody looking to transition to BPW diving or for divers looking to upgrade their current setup.
