About Our Wetsuits
Seventhwave Wetsuits are made from the world’s most technically advanced neoprene — Japanese Yamamoto neoprene — and are exceptionally warm, super light-weight and extremely flexible. Research and development is continually undertaken to bring you products designed for functionality and performance, and to give you the warmth and endurance to surf all day.
Custom-Fit is our personal fitting service where we can tailor our wetsuits to your specific measurements. If you want the best, then Custom-Fit is it.
Made with Yamamoto’s latest premium rubber, this limestone-based neoprene is 99.7% water impermeable.
Yamamoto limestone neoprene has perfect uniform independent closed micro-cell structure, which holds the wetsuit shape better and longer. Yamamoto neoprene has 93% closed cell content, compared to 60% in other neoprenes.
With a history of over 300 years, Yamamoto is the market leader in developing innovative, high-performance, rubber-based materials.
Seventhwave Wetsuits are made exclusively from Japanese Yamamoto neoprene simply because they consistently produce the best neoprene in the world. Yamamoto neoprene is:
— Made from limestone
— Exceptional thermal insulation
— Super light-weight
— Super stretchy
— Structured with uniquely high density cells.
Made from Limestone
For over 40 years, Yamamoto has set the standard for quality and innovation in the neoprene industry. Their advanced manufacturing techniques involving the use of special polymers made from limestone (as opposed to petroleum based) have led to the creation of a rubber that has a completely independent cell structure and multi-directional stretch capacity. An eco-friendly option for the 21st Century.
The closed cells are packed together at an extremely high density and each individual cell is filled with nitrogen gas to prevent water penetration and increase heat retention. The nitrogen closed cell content is over 93% — over 30% higher than most competing materials — and with virtually no water absorption means the weight of this rubber remains nearly identical in wet or dry conditions, giving you more warmth than thicker wetsuits without the weight.
Because of these special qualities, Yamamoto is super durable while remaining extremely stretchy. Super low modulus stretch with optimum cell recovery ensures a lightweight material with great strength and cell memory — in short, a durable, stretchy suit, that because of its special memory, moulds to your body shape without getting loose over time.
Did we mention superstretch? Yamamoto's highest elongation is 480-580%. Compare that to the highest elongation of the human skin under the arm, which is 60-70%. Just one of many reasons why Yamamoto is one of the top quality neoprene developers in the world.
MR7000 superstretch, SCS (Super Composite Skin) and #38 Yamamoto are just some of the many Yamamoto materials we specialize in — all designed to maximize performance, ensure you stay in the water longer, and to produce the warmest, thinnest, lightest, best fitting wetsuit on the planet.
Japanese Yamamoto neoprene: our 3mm is as warm as other 4mm.
Filled with Nitrogen closed cells: over 30% warmer than Chinese neoprene.
Made from Limestone neoprene that does not absorb any water: dryer, lighter, and more flexible.
Custom-fit: hand-crafted wetsuits made to your unique measurements.
Titanium Alloy Alpha is a super thin heat retaining film constructed out of the stuff used by NASA and specifically designed to increase heat by up to 40%. Used exclusively in our Hot Tops or inherent in our MR7000 superstretch neoprene, Titanium Alloy Alpha makes it possible to develop thinner, warmer, and lighter wetsuits that relegate the traditional, thicker neoprenes back to the dusty closet where they belong!
By simultaneously reflecting your bodyheat back onto the body and resisting cold air from the outside of the suit, Titanium Alloy Alpha really is space age stuff.
'Smoothie' has become a common way to describe single-sided nylon neoprene. This is neoprene with a nylon (fabric) finish on one side and a rubber finish (smoothie) on the other. The trend over the last 20 years has been to use smoothie in the center chest panel and center back panel. It was originally used in these panels to lower the wind chill factor, as after immersion in water the smoothie drained away any water particles. Because the smoothie did not hold water the wind chill factor against the chest was much lower.
At Seventhwave we use non-absorbent Limestone neoprene, we have found we no longer have to use smoothie. So on some wetsuits we offer you the choice of having smoothie or not.
Overlock is the simplest, most common construction method, and primarily used on our Vortex models. Two edges of neoprene are rolled together with a thread stitched tightly around them, making an extremely strong and durable method of construction.
Flatlock stitching is achieved by lapping the neoprene together in order to create a flat, comfortable and breathable seam perfect for spring, summer and autumn waters (around 12˚ upwards). It is usually used in the upper body where chaffing can be a problem. Flatlock is identified by a band of multi interlocked threads on both sides of the suit.
Glued and Blindstitched
Glued and Blindstitched methods are used when two panels are glued and butted together, then blindstitched on each side. Blindstitch uses a curved needle and does not penetrate through to the other side of the neoprene, meaning a complete, watertight seal. A glued seam is flat, supple, watertight and flexible. This construction method is commonly referred to as 'glued and stitched' and is used on all of our winter models.
Heat Sealed Tape
Heat Sealed Tape allows us to completely tape the inside seams of our winter MAX models, reinforcing the water-tight construction and adding more comfort. Also used to reinforce joins and tension points on the inside of our other models, and great for repairs.
Zig-zag stitching is used to finish cuffs and collars, and sew in zips. It is superior to a straight stitch, as it will stretch with the neoprene.
