7mm Heiwa Nylon 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

Lined outside and open cell inside: The best combination for spearfishing and recreational freediving use. Warm and hardy, you'll love this wetsuit for years to come. Downside? You won't be gliding as quickly in the water, and it won't dry as quickly as smoothskins - but who cares, as you'll be loving ever moment hanging out with fishies!

Lined outside: Lined wetsuits have the best durability. With your wetsuit lined on the outside, you can dive without worrying about accidental nicks and cuts tearing up your wetsuit.

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