Ride Engines Onsen 4/3 is the one-suit quiver killer. The geometric cell structure of Yamamoto #40 in their Onsen wetsuits are 98% water impermeable and locks in body heat, which allows this 4/3 exceptionally comfort and warmth into water temps that could warrant a 5/4.

Onsen wetsuits are constructed with 100% Yamamoto #40 neoprene. Every detail has been tested in the harshest of conditions and designed utilizing comprehensive research and development that implements environmentally sustainable materials.

Water Temp: 50°F to 57°F | 10°C to 14°C

Ride Engine are proud to introduce the all-new Onsen line of wetsuits, constructed with 100% Yamamoto #40 neoprene. Protecting and preserving our oceans, seas, and rivers—our playground, our livelihoods, our sacred spaces—drives their relentless efforts to develop and build the wetsuits with materials that are uncompromising in sustainability, lifespan, and performance.

And that commitment has led them to Yamamoto, the global leader in sustainable limestone-based neoprene. The Yamamoto #40 neoprene used in their Onsen wetsuits is significant for several reasons, both in terms of the environment and performance.

Limestone replaces the petrochemicals found in other neoprene. Minimal Water Retention: The closed-cell geometric structure of the #40 neoprene has minimal water retention (99.7% water impermeable), resulting in a wetsuit that's warmer (the cell structure has better heat retention, so a 3/2 can perform in water temperatures that you would normally need a 4/3) and lighter (less water absorption) and dries extremely fast.

The #40 neoprene is one of Yamamoto's most flexible, which ensures our Onsen wetsuits move as smoothly as you do and provide the highest level of restriction-free movement.

Our Onsen wetsuits fit better and hold up longer than oil-based neoprene suits, thanks to #40's honeycomb structure.

Solvent-free lamination of the Yamamoto #40 neoprene liners eliminate harmful Volatile Organic Compounds (VOCs), and no toxic hydrophobic coatings or laminations mean that all of our wetsuits are C-Free materials (free of C8, C6 and C4).

Meticulously designed and engineered into all Ride Engine wetsuits, our fit and construction are all about keeping you warm and protected from the elements for restriction-free movement and longer on-water sessions.

You want your gear to keep pace with your stoke. To help you do that, we have spared no effort in engineering the best wetsuits available. Made with innovative and sustainable Yamamoto #40 neoprene, these wetsuits are meant to keep you warm without restricting movement for the best sessions of your life. However, none of the work we have done matters unless you make sure that your wetsuit fits right. And there is only one right way to fit a wetsuit: tight.

But, Why Does It Need To Be Tight?
Wetsuits are designed to fit snugly against the body in order to trap a layer of water next to the skin. This thin layer of water is then heated by the body, providing a layer of insulation against the cold water. In order for this process to work, it is essential that your wetsuit fits snugly against your skin. If there are any gaps or loose areas, the warm water will escape and be replaced by cold water, leading to a drastic drop in body temperature, which often correlates to a similar drop in how much fun you are having.

How Tight Are We Talking?
A well-fitting wetsuit will feel snug all over your body with no gaps, bagginess, or folds. It should feel like a second skin sitting flush to your contours. Places to watch for gapping and proper fit include under the arms and in the crotch area, as these are two places where people struggle with the fit the most. It may take some gentle tugging and rearranging to ensure the suit fits flush in those areas. If you can’t get it snug, size it up or down and see if you can fix the issue. Specifically, look for pockets of air, as those will become pockets of water that will chill you once you get wet.

It is important to remember that your wetsuit will loosen up on the water, so err on the side of tight over loose.

So Any Tight Wetsuit Will Work?
The short answer is no. Not all wetsuits are made the same, and not all wetsuit materials are made the same. While it may be tempting to pick up something cheap from a discount brand or big box stores, the neoprene they often use will not perform the same way, not to mention it isn’t good for the environment.

We use sustainable Yamamoto #40 limestone neoprene that is hydrophobic to keep you warmer longer. This neoprene also offers superior flexibility, meaning you can get a snugger fit without sacrificing movement.

Can It Be Too Tight?
The simple answer is yes, there is such a thing as a too-tight wetsuit. When you try on your wetsuit, you want to be able to move relatively freely. Your movement in a dry wetsuit will be a bit restricted, so be sure to keep in mind that once wet, it will have more flexibility and loosen just a little bit. A too-tight wetsuit will restrict your circulation, making movement difficult and causing you to get cold faster.

Visit your Ride Engine authorized retailer, and be sure to try on a couple of sizes to find the right fit. Stay committed to finding one that is just snug enough to keep you on the water as long as you want.

We’ve dedicated ourselves to making Ride Engine wetsuits last. With state-of-the-art Yamamoto #40 neoprene in our Onsen coldest weather suits and sustainable limestone neoprene in our Sensor spring and summer suits, you can know your investment will be around for a long time.

However, how you take care of your wetsuit can have a significant impact on its longevity. Here are our top tips on how to keep your wetsuit looking like new for years to come. Hint- tossing your wetsuit in the trunk of your car post-session and forgetting about it till next Tuesday isn’t on the list.

Rinse, Rinse, Rinse
As soon as you can after getting off the water, rinse your wetsuit in fresh, cold, or cool water. While running water over it out of a faucet or a hose is a good start, if you really want to get all the salt water out, repeatedly dunk it in a bucket or tub. Make sure to flip the wetsuit inside out and right side out to ensure you get all the sand, dirt, rocks, leaves, and grass off of it.

Avoid using hot water as it can degrade the neoprene over time. While it can be super tempting to rinse off in a hot shower while you take your wetsuit off, just don’t do it. Wetsuit off, then hop in the shower.

If you pee in your wetsuit, which we all know we shouldn’t do but do anyways, pay special attention to ensure you get that all rinsed out too. It’s really hard on your wetsuit, and the crotch is the last place you want your first leak.

Hang It All Out
Once you’ve got your wetsuit good and rinsed, it is important to hang it up to dry. Turn it inside out and drape it through a coat hanger or over a chair. Be sure not to hang it by the neck and shoulders because this will stretch it out over time. Do not hang your wetsuit out in direct sunlight, even on a cloudy day, as UV rays can degrade the neoprene. Once the inside is dry, flip it right side out and let it continue to hang until completely dry.

Store It Right
Your wetsuit is not a beach towel that can sit wadded up in the corner of your bathroom for a week. Once you’ve got it completely dry, store it unfolded and completely flat in a cool, dry, and dark spot. Make sure it is out of any sunlight. Great spots can include under your bed or high on a long closet shelf. In the absence of somewhere flat to store it, use an empty shipping tube or thick wrapping paper roll to fold it over. This way, you can fold it in half without creating creases.

Easy Does It Getting In and Out
No matter how well we design a wetsuit, there is no getting around that putting it on and taking it off causes inevitable wear and tear. However, if you pay a little attention, you can help to minimize it. Take your time, and don’t be in a rush. When putting it on, be sure not to tug and pull at the seams, zippers, or openings. To take it off, roll the suit inside out as you go, peeling it off yourself. The bonus of removing it this way means it is already inside out for rinsing and drying!
