3mm Heiwa Superstretch Superelastic

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

Double lined: Double-durability! This is the most durable combination you can get. Downside? It may not be as stretchy or soft as other combinations, as stretch will rely on the elasticity of the fabric.

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.

Lined inside: Ensures your wetsuit is durable and even lets you put your wetsuit on without needing any lube!
