7mm Heiwa Smoothskin Open cell

Heiwa is an excellent mid-range, solid, hardy wetsuit that  maintains its thickness well when you dive under and over time. If you're paranoid about your wetsuit compressing over time, and don't mind something a little less flexible (but still great) - Heiwa is great and will last you for years to come

Smoothskin open cells: The warmest, fastest, most comfortable and flexible fit you will ever wear. If you're into competitions - these are the wetsuits you need. However, these wetsuits are very delicate and will need very gentle handling, as well as plenty of lube for getting in and out.

Smoothskin: Glide through the water faster, with lower friction and drag. Warm up quicker as water beads off and evaporates quickly

Open cell: Stay warmer as open cell traps water right next to your skin. You'll need lube to put this on
