Sidemount BCD IST Bladder (21Lb) SMB21
For low-profile side mount dives in the tightest spots such as wreck or cave exploration, IST’s SMB-21 with 21 lbs of lift fit the profile perfectly. It is a complete integrated system that can be used for warm water diving with wetsuits and aluminum tanks, or cold water diving with drysuits and steel tanks.
New for 2014, these side mount bladders are the result of hundreds of side mount dives in real world conditions by experienced side mount divers and cave explorers. IST’s SMBs are the lowest profile; streamlined buoyancy devices, which provide maximum balance and ideal, trim control. With IST’s bladders, you move through the water easier and more efficiently.
IST’s SMBs are completely scalable from single tank recreational to double tank technical, and have components that are even compatible with back mount diving. The minimalist harnesses also give more chest room for easier access to attachments and better maneuverability underwater. The SMB-21 is constructed of armor- 1680 Denier Nylon with a coating of TPU fully shielding them from abrasions, tears or punctures.
