Hollis SMS Katana
Sidemount System
Honed by extensive testing and refinement, the Hollis SMS Katana, designed by Nick Hollis in partnership with leading cave diving instructors, is a cutting edge cave penetration tool without equal. The SMS Katana design builds on the proven SMS100 and SMS75 sidemount systems but was further streamlined to reduce drag and allow for easier movement in confined spaces providing optimal performance in the warm water cenotes and caves of northern Florida and Mexico.

Hollis SMS 75
Sidemount System
Hollis has become a leader in the sidemount market. It is not just a fad and not just a tool for cavers, it’s here to stay and is growing. The SMS75 is an evolution from years of sidemount development, which started with the SMS100. A product that has been copied, modified and a benchmark for technical sidemount for years. Even more popular has been the lightweight SMS50 line. These two have taken sidemount mainstream and the building blocks this new harness. While it will cater more to hardcore cave divers, SMS75 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 SMS75 will also support rear mounted tanks and reversible inflator positions
