XDeep SMB 140cm Closed can be inflated using a low-pressure inflator hose. It comes complete with an over-pressure dump valve.

Ingeniously, the closed SMB can be transformed into a makeshift life ring using a double-ended bolt snap. Clip one end to the small loop at the top of the SMB and the other to the strap at the bottom, thus creating a ring.

XDeep SMB’s are made from Nylon 240 dTEX, a high-quality material made in the USA and specifically designed for use in maritime signalling equipment and life jackets.

The reflective strip uses 3M Scotchlite reflective tape, which carries a Solas maritime visibility certificate.

A clear plastic tube is fitted to the side of the XDeep SMB to provide a place for small notes or a glow stick.

A big sling underneath makes attaching a spool or reel easy and filling the bag a breeze. A small loop of bungee keeps the SMB neat and tidy in storage.
