Rebreather, extended range, and sidemount divers have different requirements for a DSMB than recreational divers. From the heavy-duty 420D nylon fabric to the over-sized stainless attachment D-ring on the bottom, this DSMB is a quality product purposefully designed with the technical diver in mind.

• Closed bottom design - 45 in (114 cm) length x 10 in (25.4 cm) circumference

• The stainless steel tipped inflator allows oral or QD hose inflation

• 2 in (5 cm) wide SOLAS reflector tape all the way around

• 2 x 4 in (5 x 10 cm) white panel at the top to write on with a permanent marker

• 1.5 in (38 mm) over-pressure valve with pull cord for easy deflation and roll-up

• 1 in (25 mm) plastic attachment D-ring at the top
