    Comments about Hollis Gear Hollis Sidemount SMS 50 Sport Harness:

    Nice little Side mount rig. I also have the SMS 100. This harness is good for the diver that does not want to carry a lot of heavy tanks. Just a nice setup. I use with 2 aluminium 80's.

    Questions about this item:

    Shopper  First question I have is the specification of tank I can use. According to the specification, it says "Cylinder Capacity: One Tank at a time". Is this mean it cannot take two tanks for side mount at same time???? It should be able to take 2 AL 80 tanks? Second question I have is if this is a complete set? Do I need something else for two tank sidemount? Thank you, THank you.
    Shuai H  It comes with (2) Tank bungees, (2) SS Cam bands, (4) SS Bolt snaps & line included with kit, so you got complete set for TWO tank setup. And as printed on the Hollis SMS 50 it can carry 2 X 15L tank or a single 20L tank, the aluminum 80 tank is 12L. So yes, you can carry 2AL 80 tanks with SMS 50 Sidemount system out of the box.
    Ken S  What are the differences between the Sport Harness and the Adventure Harness (both SMS 50 of course)?
    Christian R  The Sport Harness has the LP inflator hose and dump valve routed to between the shoulder blades at the top of the wing. On the Adventure Harness, the LP inflator is located at the lower left/left kidney area between the body and the wing for easier streamlining in overhead environments. The benefit to the Adventure Harness is that it is less likely to get snagged on an overhead obstruction.
