Simple, Rugged and Minimalist. The ST System combines Hollis's most popular single tank components into one, both including the Solo harness for the ultimate in simplicity and streamlining. This kit is preassembled from the factory and includes unique components. For warm water and travel destinations Hollis has the ST Travel, which includes the ST22 wing, Aluminum backplate 2.0, Delrin cam bands and Backplate Back Pad 2.0.

The Hollis Solo Harness System is designed to meet all the needs of demanding technical divers. The Solo Harness System is clean, simple, and foolproof! The Solo's streamlined design enhances comfort with less drag. The Solo's continuous one-piece harness webbing system limits failure potential. Harness is equipped with stainless-steel D-rings with four-pre-bent on the shoulders, two on the waist strap and one on the crotch strap. The Hollis Solo Harness System has removable shoulder pads that accept additional stainless-steel D-rings. Harness has a stainless-steel latch-style waist buckle. All hardware is manufactured from 316-marine-grade stainless-steel. The Solo Harness System weighs 16 oz. (450 g).

The Hollis ST line of wings are a series for single tank diving. The design features a 360 Degree tapered profile, to increase lift towards the hips, promoting better horizontal trim in dive position while still allowing perfect surface floatation. Tank slots and tank cradle are included on both models, which allows you to connect your wing and backplate without the need for a single tank adapter plate. This reduces weight and unnecessary accessories while traveling.

The bladder is a two-piece design, with a rugged 1680 Cordura nylon outer shell to prevent abrasion and punctures, and a 420-denier nylon internally urethane laminated with radio frequency (RF) welded seam inner bladder to maintain the buoyancy. The lower OPV is easy to reach for venting gas while horizontal or heads down, and the inflator design is a K style with a rugged crushproof rubber hose for easy positioning and oral inflation should you need to. Both ST wings come standard with 3/8" threaded quick disconnect inflator hose. Welded flange and one-piece retainer for servicing without the need for tools. Elbow offset to avoid tank valve/regulator interference and streamlined hose routing. The ST22 provides 22 lbs. (10 kg) of lift.

The Hollis 2.0 Backplate Line is the foundation for the new Hollis technical harness systems. They feature improved ergonomics for a more comfortable fit, but are still short enough to fit smaller frame divers. The aluminum version weighs in at 1.5 lbs. (680 g), it is laser cut and CNC bent, which give this awesome new appearance. The Aluminum backplate is laser cut from EN AW 6061 aluminum and hard anodized in black for a marine grade finish. Geometry of the webbing slots is similar to Hollis prior design to ensure reverse compatibility for all Hollis buoyancy accessories, so if you have a current Hollis harness, wing or weight system, this new plate will fit. Aluminum plate is 0.12" (3mm) thick.

Being a technical diver does not mean you have to uncomfortable when you are diving. Add some cushion and comfortable support to your back plate with this Hollis Back Plate Back Pad. The Hollis Backplate Back Pad 2.0 is a comfortable two-piece design with added lumbar support, which easily pivots out of the way of your doubles tank bolts and cam bands when assembly or disassembly as needed. Sold as an accessory but also included with Hollis new Technical Harness systems. Note: Is not compatible with previous generation Hollis's back plates.
