The Hollis SMS75 Complete Side Mount System is an evolution from years of side mount development, which started with the SMS100. A product that has been copied, modified, and a benchmark for technical side mount for years. Even more popular has been the lightweight SMS50 line.

These two have taken side mount mainstream and are the building blocks of this new harness. While it will cater more to hardcore cave divers, the Hollis SMS75 Complete Side Mount System was created to handle all environments. Proper trim is key and the wing is designed to promote horizontal diving with increased lift towards the hips where it’s needed most and without modification. The Hollis SMS75 Complete Side Mount System will also support rear-mounted tanks and reversible inflator positions.


  • Trapezoid shape to promote horizontal trim
  • Adjustable and removable wing bungee
  • Designed for cave or open water side mount
  • Cam slots for single tank and grommets at 11” for banded doubles
  • Reversible Inflator & Dump assembly
  • Rigging kit included: Tank bungees, SS Cam bands, SS Bolt snaps & nylon line
  • Includes sternum strap & crotch strap
  • Inner located elbow to avoid overhead interference
