The new HOG 72in SMB with Low Profile Exhaust and Spool Combo Hi-Vis Orange is a game changer. This SMB is lighter and more compact than any other 72in SMB. And that includes it having a 33' spool. With every method of inflation including inflator hose, manual and bottom feed there is no reason you cannot get this thing inflated. It features a low profile over pressure exhaust built into the inflation tube which took years of R&D to develop. This SMB is smaller, lighter and more streamlined than almost all 3' SMBs on the market.
