Sidemount Harness Options for Homemade Systems

There are a number of stand-alone sidemount harness options on the market. Whilst not complete sidemount diving systems, they may warrant consideration if building a mixed, or DIY, configuration rig.

You can configure your sidemount harness, then simply add the wing and bungee system of your choice.

‘H’ Style Harness showing custom hardware sidemount harness option
 
Andrew Goring at SUMP UK is well known for his excellent range of custom sidemount hardware – so it’s natural that he should produce a range of sidemount harness options to suit every need.  
 
There isn’t one specific harness option – but rather, you can consult directly with Andrew to specify exactly which design and hardware options you prefer.

Deco Sidemount Harness

Deco Sidemount 2

 

There are two harnesses available;  a traditional harness (shoulder straps to the rear lumbar plate) and an ‘H’ style harness (shoulder straps routed to front of harness via ‘T’ attachments).  Both harnesses are lightweight and minimalist; providing all the functionality that you’d need with zero superfluous clutter.  

Many other types of sidemount wing could be attached to this harness. The harness is supplied with 6ft of 5/16th bungee and two bolt-snaps, so the diver can rig out their own tank bungee method (loop, sliding loop, independent, ‘old school’ etc). Both harnesses include fixed front D-rings and offset (drop) D-rings at the read.

The rear crotch strap D-ring is a dual/double ring design; giving more options for equipment attachment. There is no weighting system included with the harness.  My solution for weighting, on ‘bare’ harnesses like these, has always been to put a couple of stand-alone weight pouches directly onto the spine webbing.  

It works great and keeps things very simple. These would be an extra purchase…  or you could just thread weights directly onto  the spine strap for a more permanent option (less ideal for travelling). The regular harness costs $145.99 and the ‘H’ style harness is $163.99…..  very cheap compared to most on the market.

Santiago Ultimate Harness

Santiago Ultimate Sidemount Harness
 
This Mexican produced sidemount harness follows a common minimalist theme and is designed to provide a mounting option for the Z-Trim and Stealth 2.0 wings.  It features low-profile D-rings and manages to eliminate heavy lumbar/shoulder plates through innovative use of ‘folding-back’ the webbing through weight retainers. It also comes with a double 4.5mm high-strength bungee to provide redundancy.  One very novel feature is the LB-SR (Sliding Ring) System: an adjustable sliding D-ring that allows quick adjustment to precision cylinder trim whilst wearing/diving the rig.
