Zeagle Hollis SMS 75 Side-Mount System BCD - BCD351 02-SM/MD
The Hollis Side-Mount SMS75 is an evolution from years of side-mount development, which started with the SMS100. The Hollis Side-Mount System is 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 the building blocks this new harness. While it caters more to hardcore cave divers, SMS75 was created to handle all environments. Proper trim is key in side-mount diving and the wing is designed with a trapezoid shape 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 with cam slots for single tank and grommets at 11" (27.9cm) for banded doubles and reversible inflator positions.
