What thickness wetsuit do I need?

Thickness is written as two numbers, like 3/2. The first is the millimeters of neoprene through the chest and core, the second is the arms and legs, thinner so you can still paddle. A 3/2 is the cool water full suit most women reach for through the shoulder seasons, made for roughly 56 to 65 degree water. A 4/3 covers roughly 51 to 58. A 5/4 is winter, for the mid 40s to low 50s. When the water warms up you drop out of a full suit entirely and into a spring suit or a jacket. The honest version: the number on the label is only half of it. How long you stay out, how hard you are surfing, and how you personally run all move the answer. If you are the one who gets cold first in your crew, size up in warmth before you size up in suit.

What is the difference between a chest zip, a back zip, and a U-Zip?

A chest zip closes across the front and you get in through the neck. Less water finds its way in, because there is no long zipper running down your spine, and there is less bulk against your back when you are lying on the board. A back zip opens wide down the back and is easier to get into on a cold morning when your hands are not working yet. We build both, and a third way in. The 7 Seas comes in chest zip and back zip in the same thickness, so the choice is yours and it is not a compromise either direction. The New Seas uses the Axxe U-Zip entry, a zipper that runs shoulder to shoulder across the back for a much bigger opening. It is the easiest suit we make to get on and off, and it seals shoulder to shoulder so the opening never costs you warmth.

How should a women's wetsuit fit?

Snug everywhere, tight nowhere. A wetsuit works by holding a thin layer of water against your skin and letting your body warm it, so any gap is a place that stays cold. You should be able to reach overhead and paddle without the suit pulling at your shoulders, and there should be no loose pocket in the small of your back or behind the knees. Ours are built on anatomically engineered body lines, which is the technical way of saying the suit is shaped for the surfer wearing it rather than scaled down from a men's pattern.

What size Sisstr wetsuit am I?

Our wetsuits run in numeric sizes 2 through 14. Start with the size chart, which is also linked on every wetsuit product page: view the size chart.

How do Sisstr wetsuits keep cold water from flushing in?

Flushing is cold water pushing in past a seal, usually at the neck or the wrists, and it will end a session faster than anything else. Our suits seal at both. The neck uses Glideskin, a smooth neoprene that sits against the skin rather than against a layer of fabric. The cuffs use liquid tape seals at the wrist and ankle. Inside, the seams are triple glued and blind stitched, then reinforced with our Neo 3.0 stretch tape at the crotch, the knees, and the points that take the most stress.

How do I take care of my wetsuit?

Rinse it inside and out with fresh water after every session. Hang it to dry in a cool shaded spot, never in direct sun. And when you are changing, do not stand on it. That last one is how most suits die. A wetsuit is the most expensive thing most of us own that we then leave in a hot car. Ten minutes of care buys you seasons.

What is the wetsuit warranty?

One year from the purchase date on seams. One year from the purchase date on neoprene. Six months on smoothy material. Punctures in the smoothy from fingernails are not covered, which is worth knowing when you are pulling the suit on. The full warranty and repair process is covered above on this page.

What are the 7 Seas, High Seas, New Seas, and Summer Seas lines?

Four lines, one question: how cold is your water and how you like to surf. 7 Seas is the core cool water line. Full suits, built for the months when the water turns and the lineup thins out to the women who came ready. High Seas is the performance line, the lightest and stretchiest suit we make, built on I-Foam neoprene and stitchless outer arm seams for the surfer who wants nothing between her and the wave. New Seas is the newest of the four, built around the Axxe U-Zip entry that opens shoulder to shoulder, the easiest suit we have ever made to climb in and out of. Summer Seas is the warm water line: spring suits, jackets, long sleeve cheekies, the pieces you reach for when a full suit is more than you need. Shop all wetsuits.

What is limestone based neoprene?

Most neoprene starts from petroleum. Ours starts from limestone. The rubber itself is 100% limestone based, and it comes out lighter, warmer, softer and stretchier, which is why the suit is easier to pull on and easier to paddle in. The fabric content on the label reads 80% neoprene and 20% nylon because a finished wetsuit panel is the rubber laminated with a stretch nylon jersey. Same suit, two ways of describing it: the label describes the whole sandwich, the limestone describes the rubber inside it.

Are Sisstr wetsuits sustainably made?

We build them to leave a lighter mark on the water we surf in. The neoprene is limestone based rather than petroleum based. The jersey fabric is dope dyed, which locks the color in at the fiber and cuts the water and energy a dye house would normally use, and it is laminated with AquaA, a water based lamination with no solvents. The mills that make the fabric are Bluesign approved. The knee pads are upcycled Supratex. None of that is the whole story of a wetsuit's footprint, and we would rather tell you exactly what we do than round it up to a word like green. Read more about how Sisstr is made.
