Sure, but the word “premium” doesn’t really mean all that much and doesn’t let you know what exactly you’re purchasing. Instead we tell you exactly what our wetsuits are made out of and why they are better than our “premium” competitors, all without confusing made-up tech jargon.

The cell structure of the neoprene makes it 99.7% water impermeable, greater than anything else available. This makes it lighter and warmer. It’s also ultra-soft and durable. We think you’ll be stoked from the moment you try it on.

The main difference is in the elongation properties—#40 is stretchier than #39—but it's also worth noting that #40 is slightly heavier than #39. We only use #40 rubber in the upper body because when we tested the suits that was the only place we noticed the stretch, and there's no reason to make a heavier suit just because 100 percent #40 Yamamoto sounds good for marketing purposes.

Fuzzy linings feel great in the store and work great when you are dry but once wet any insulation benefit is significantly decreased. Plus, water is not a great insulator and fuzzy linings readily absorb and trap plenty of water. Neoprene is a far better insulator when wet, in fact, that’s why we wear wetsuits now and not wool sweaters like surfers did in the past. Would you rather have a 4mm wetsuit with 1mm of neoprene and 3mm of fuzzy liner? Or an all-neoprene 4mm suit? Learn more about how wetsuits work here.

We don't have a model that we call a "4/3" but depending on what you're looking for, either our Hooded 3mm+ or Hooded 543mm will do the trick. They're both comparable to other brand's hooded "4/3" wetsuits. Here's a comparison to help:

- The FERAL 3mm+ is comparable to many of our competitors’ unlined (no fuzzy stuff) 4/3mm wetsuits, while being warmer, lighter, flexible, and longer lasting.

- The FERAL 543mm is comparable to our competitors’ lined (thick fuzzy stuff) 4/3mm wetsuits while also being warmer, much lighter, more flexible, and longer lasting.

Rinse inside and out with cool freshwater and hang from the waist out of the sun. Once the side facing out is dry, turn it inside out and let that side dry. Store indoors on a hanger draped from the waist.

Our suits are designed by Alex & Buzz in San Francisco, and manufactured in Thailand.


Most likely, yes (this goes for any size). Check the size chart to confirm. If you are unsure, contact us. And don’t worry, you can exchange your unused suit for free in the first 30 days if you want a different size.

Please contact us with your height and weight for a sizing recommendation. We suggest ordering a backzip for your first wetsuit because they're easier to put on and take off than a chestzip. If this is your first wetsuit in many years, we recommend you check your current weight before looking at the size chart. When in doubt, email us!

Keep in mind that Yamamoto suits will take a couple surf sessions to stretch out a bit. Your new wetsuit actually should start out a bit tight. We suggest trying on your wetsuit a few times and moving around in it a bit—this should begin the stretching out process and give you a better idea of how the suit will fit after surfing in it. Many customers have told us their new FERAL wetsuit felt tight at first, but after surfing in it a few times the fit was perfect.

No worries. We offer free exchanges on unused suits, including shipping, for the first 30 days.


Our wetsuits are always priced fairly to allow everyone to get a good deal on a great wetsuit on any day of the year. We haven't had a "sale" since our first year of operation (2015), so we wouldn't recommend waiting around for one:)

Our wetsuits are available at Mollusk Surf Shop in San Francisco, Santa Barbara, and Venice Beach, and Saturdays NYC in Manhattan, and Newport Beach. Sizes may be limited at times. If ordering online please refer to our size chart, in general our wetsuits fit pretty true to size. With free returns and exchanges on unused suits, you can order worry free.

Bummer! Send us a message and get an update on when your size will be available.

No, we don’t plan to have future preorders and we can’t hold a suit for you—even if you want to pay us now.


Yes, it's really just the two of us. We have no employees, no investors, and no big holding company to tie us down. Once we outgrew shipping all the suits ourselves, we enlisted the help of a small family-run business to take care of our fulfillment and warehousing. We’re still calling all the shots and personally responding to your emails. Thanks for the support.

Not at the moment. We decided our dollars and hours were best spent on wetsuit design. We figure most people would rather save a few bucks than see Rick Kane sporting our suit at their local break.
