The Mares Flexa 5.4.3. is a Trilastic material wetsuit which means it is composed of varying ultra-stretch neoprene thicknesses. It is designed to protect in key areas and be flexible in others. For example, it has a Thermo Plush lining at the chest to retain your core temperature and an additional neoprene panel to cushion the spine and shoulders (known as a “back protection system”). The 4 and 3mm panels are to provide more flexibility in areas that require more movement such as behind the knees and under the arms.

The Flexa has double glideskin at the ankles, wrist and neck to slow flushing; it has a front entry slightly off-centre zip with neoprene flap which makes it easy to don and doff; the flat lock stitching is designed to be comfortable against bare skin.

There is an optional “Smart” pocket which secures to the thigh with a clip and Velcro. It is strong and stretchy with secure bungees inside for carrying accessories. The suit also has an integrated retaining ring to hold the divers hood and instrument grips at the wrists. This wetsuit is suitable for diving in temperate water.

Features
  • The ultimate expression of trilastic material design
  • Varied thicknesses strategically placed in different areas of the body
  • Soft ergonomic custom closure
  • Back and shoulders comfort system: an additional layer of neoprene stitched in the back for added comfort and protection
  • Front zip with smooth neoprene flap for greater comfort and isolation
  • Integrated buckle on the leg for hood attachment or attachment of the dedicated smart pocket (sold separately)
  • Instrument grips on both wrists

Add Mcnett Neoslix to aid with the donning and doffing of the suit as well as to prolong the life of the seals too.
