  • What is a freediving wetsuit?
    It is a wetsuit made using the newest generation Neoprene that can only be manufactured in Japan. The Neoprene itself relies on nitrogen pockets for thermal isolation and the wetsuit can only be hand made by skillful professionals The manufacturing procedure is very complex and takes a long time, because the wetsuit is first assembled, then glued and then surface stitched only. It is so flexible, warm and comfortable; it almost feels like a «second skin». The Picasso wetsuits fit the freedivers like a glove, literally, giving them the sensation of being wrapped in a perfectly molded silky latex material, with that beyond description "Jell-O" feeling.

    What is the "Chicle®" wetsuit?
    In Spanish, chicle means «chewing gum» ... which explains it all. It is so flexible, warm and comfortable; it almost feels like a «second skin». The Chicle® fits the freedivers like a glove, literally giving them the sensation of being wrapped in a perfectly molded silk suit, with that beyond description "Jell-O" feeling.
    • 100% waterproof
    • very flexible and stretchy
    • as hydrodynamic as a marine mammal's skin
    • more than twice warmer than any similar thickness wetsuit in the market(a 5 mm thick Picasso Chicle®will be warmer than any other 8mm thick wetsuit)
    In short, the Picasso Chicle® is a special wetsuit that is incomparably soft, resilient, and stretchy. Due to it's excellent characteristics in addition to very high compression resistance, the dynamic Chicle® is ideal for professional commercial diving, freediving and freedive spearfishing :: What about the other Picasso wetsuits? All Picasso wetsuits are hand made in Europe, using the world's finest Yamamoto® Japanese Chloroprene grade SUPER-LIGHT Neoprene. With a specific gravity of only 0.13 g/cm³ and a very low modulus (between 10-100%, the lower the modulus, the higher the comfort level), Yamamoto® 39 is extremely light, soft, and has excellent stretch. Due to it's key characteristics, it is best suited for leisure diving suits, a new generation of "zipper-less" suits, in addition to being the neoprene of choice by the world's top triathlon athletes.

    What makes the Picasso wetsuits so different?
    Picasso wetsuits owe their extraordinary thermal insulation and comfort features, to the hundreds of thousands of tiny nitrogen bubbles within the Neoprene itself. This is similar to how a "thermos" works, using air for insulation. Air, being 80% nitrogen, is one of the best gaseous insulation agents.

    What is the difference between “open-cell”, "split-cell" and “skin-in” wetsuits?
    Freedivers generally refer to the best freediving wetsuits as “skin-in” or “open-cell” when these wetsuits have no fabric lining. This is simply because wetsuits are divided into two categories: Wetsuits with fabric lining and wetsuits without fabric lining. By lining, we mean fabric material, such as Nylon, Lycra, plush, etc., that covers the inside of the wetsuit, which is in direct contact with the diver's skin. (However, both applications are not technically correct. But we will compromise and accept them, in order not to complicate matters.)

    "Skin-in” may also be what is referred to as “smooth-skin” inside. Meaning that the Neoprene sheet was used as is, without “splitting”, therefore defeating the purpose of perfect fit, adhesion and waterproofing. Many wetsuit manufacturers will use this design and market the wetsuit as “open-cell” or “skin-in”, thus confusing the customer.

    What does "BioTermic®" mean?
    BioTermic® is a space age composite coating applied to the exposed "split-cell" inside of some of Picasso's wetsuits, Neoprene vests, gloves and socks. It was invented by NASA in its quest for a heat-reflecting material that would protect the space vessels from overheating as they enter the atmosphere on the way back to earth.

    The drive behind Picasso's BioTermic® coating was fourfold: 1) unlike standard suits, because BioTermic® does not absorb water and prevents it from "clinging", the diver is not greeted with cold when re-wearing a suit that has already been submerged in water. Comfort levels are significantly increased; 2) typical jersey/rubber combinations allow for the growth of bacteria on their surface. BioTermic® coating is antibacterial; 3) Nylon on one side of neoprene allows for more stretch than nylon laminated on both sides. When a BioTermic® coating is applied to one side, you gain all of it’s benefits, plus the added stretch; 4) BioTermic® is slick as Teflon® and reflects back all Infrared radiation. This makes it the perfect barrier against heat transfer between the diver and the water and allows the diver to wear the wetsuit without any form of lubrication.

    A fifth characteristic and the reason BioTermic® is the choice of top competitive freedivers is, when BioTermic® is applied on the outside of the suit, it drastically reduces water resistance/friction(0.032). This increased hydrodynamism allows for deeper dives and faster times, while using fewer strokes.

    Picasso is the only manufacturer in the world who applies such a coating, directly on the "split-cell" surface, so the wetsuit remains an "open cell" (split-cell) wetsuit, but with the BioTermic® coating.

    How is it that special Neoprene manufactured and how could you describe it?
    The Neoprene used in the Picasso wetsuits is manufactured in various thicknesses and is supplied in rectangular sheets. At its first stage, the sheet is all rubber. Both surfaces look and feel the same: smooth and very soft to the touch rubber (skin), as if polished.

    When the Neoprene sheet is cut, thousands of minuscule suction cups forming the Neoprene are exposed, like a rich “soufflé” or “chocolate-mousse”, filled with air bubbles. This is why divers must lubricate the wetsuit before donning it. Some use talcum powder, soap and water or hair conditioner and water.

    At this stage, the Neoprene sheet is ready for the final treatment. It could either be turned into a “smooth-skin-out, split-cell-in" wetsuit, or into a "Nylon (or Lycra) out, split-cell-in” wetsuit. The second choice, is made by applying or fixing a sheet of Nylon or Lycra fabric to the surface of the Neoprene and then feeding it through a mechanical blade that slices the inside into the perfect “second skin” for a Freediver: "the "split-cell-in", also referred to as “open-cell” or “skin-in”.

    Could you give some technical data with a description of this space-age Japanese Neoprene?
    Yamamoto's technical rubber is called "Chloroprene." The performance of Chloroprene is dependent on the raw material and it's closed cell condition - if one or more cells are interconnected or if the wall of an individual cell is ruptured, the performance of the rubber is impaired.

    Yamamoto has been successful in producing the perfect independent closed micro- cell structure. This has been achieved by employing a special polymer derived from limestone along with the most advanced manufacturing techniques - all developed by Yamamoto Corporation.

    Yamamoto's rubber is made from limestone - over 99.7% calcium carbonate. The function and quality of technical rubber is decided not only by the purity of the raw materials - the limestone that goes into Yamamoto's technical rubber comes from one source - but also by the independent closed micro-cell structure. The independent cell structure offers the following advantages:
    • The individual cells do not absorb water. In addition, each cell of the complete independent closed cells are filled with nitrogen gas and thus do not absorb water at all and realize excellent heat retaining properties and thus offer excellent thermal insulation or heat retaining properties.
    • As a result of its special properties, no water absorption, weight of the material in dry and wet is kept almost same and therefore wetsuits made of this material are not heavy when submerged.
    The closed cell content of Yamamoto Chloroprene is more than 93%, 22-33% higher than competitors whose closed cell content is typically in the 60-70% range. What does all of this mean to the Divers?This means that the divers are assured of the lightest weight, warmth and comfort. Why? Simple. Check out the features below:
    • Super lightweight
      The ratio of closed cells of our neoprene is over 93%. This ensures lightweight and a lower specific gravity - essential qualities for wetsuits and swimwear.
    • Super heat retention
      The nitrogen gas inside the individual closed cells result in exceptional heat retention and efficiency. Super stretchability Our Neoprene's highest elongation is 480 - 580% compared to that of the human skin's maximum elongation of 60-70% available at the armpit.
    • Uniform cell structure
      The uniform micro-cell structure of our neoprene ensures that if any part of the material surface is defaced or scarred, new independent concave micro-cells are exposed insuring continued functionality.

    What is the difference between the traditional wetsuit and the Picasso?
    The traditional wetsuit you find in dive-shops presents all of the following disadvantages:
    • It allows water transfer to the inside of the suit, which then forms a liquid barrier between your skin and the neoprene. Water then absorbs your body temperature trying to match it, thus draining your own warmth while giving you the impression of not being cold. But since the water transfer is occurring during the entire dive, you’re being steadily robbed of much-needed energy. You will be exerting yourself unknowingly, in order to heat up your own insulating water! This means your dive will become shorter and less productive and your breath hold time will be much less than your own potential!
    • It is stiff, bulky and constricting for your movements. This includes restriction of your chest expansion for breath holding! That’s because the neoprene is heavily covered and lined with all sorts of unnecessary fabric in order to make it warmer. Therefore it’s heavy and it doesn't stretch. This is why it needs long lengths of zippers and heavy-duty sewn seams for maximum hold, as well as a jacket with a separate hood, a separate vest, etc.
    • It is a wetsuit that requires your physique to fit the pre-made suit, not the suit to mold to your physique due to all the reasons listed above. Should your size be slightly different than a perfect model's, you'll have to be content with a "loose-long-here" tight-short-there" wetsuit, or perhaps even have to pay and wait for an expensive, custom-made suit.
    • It causes drag in the water. Due to all the reasons mentioned above, the water will have a greater braking effect on your swimming, with all the negative results that reduce your diving capabilities.
    • It doesn't compress(a necessity for freedivers). Effort is constantly being expended on the way down and on the way up. Also, the deeper you’ll dive, the colder you’ll get, as your body compresses itself, more than the wetsuit, which will allow flooding with larger amounts of cold water (even colder at depth, due to the thermo-cline).
    • It will make you extremely cold while riding on the boat, because once the vessel speeds up in order to change locations or is returning back after the dive, you'll be trying to find shelter from the wind, trembling from the unpleasant cold-to-the-bone-marrow feeling, from the rapidly evaporating water on your wetsuit, due to the action of the wind. Soon you will find yourself trembling, curled up in the fetal position, or looking for a large plastic bag to wrap yourself with!
    • It allows bacteria growth and will take much longer to clean in order to eliminate the urine smell, which has been deeply absorbed by the fabric lining. No matter how long you hand or machine-wash it, soak it in detergent, disinfectant, perfume or whatever, it will have the ammonia smell embedded in it!


    The Picasso wetsuit on the other hand, have none of the disadvantages listed above.

    Instead, it will;
    • Keep you DRY since a Picasso will not allow water in. How? Simply because the Picasso Neoprene is so “stretchy” and smooth, it will stick to your skin and mold to your body like latex surgical gloves fit your hands. Most of Picasso wetsuits also come with extra waterproofing sealants on the ankles, wrists and hood, thus keeping you totally dry during the entire dive. Because of its stretching capability, you can dive as deep as you would like and still the Picasso suit will stay completely sealed. The Neoprene used in the manufacturing of the Picasso wetsuit will itself be the insulation, allowing your body to reserve all of its energy for diving and hunting, instead of trying to warm up the surrounding ocean! This will allow for longer and certainly more pleasurable hours of enjoyment in the underwater world, feeling toasty warm and snug, extending your breath holding ability to its best capability.
    • Stay soft, light and silky thus giving you freedom of movement, just like the professional triathlon wetsuit, which is also made of the same material as the Picasso wetsuit and is used only for the highest athletic performances. This innovative wetsuit manufacturing process relies on gluing rather than heavy stitching for its assembly, which increases the already superior elasticity. Due to this unique, gluing process, all Picasso non-tropical, wetsuits come in two pieces: a jacket with a built-in hood and a long john trouser (farmer-john type).
    • Will fit you like a glove. An off-the-shelf Picasso wetsuit should feel like wearing a latex surgical glove. Being that flexible and smooth, it is also very tolerant of various body shapes and it will adapt to your size and mold to it, not the opposite! We also have 10 different standard sizes in stock.
    • Won't drag in the water, because of the very thin Nylon or Lycra layer covering on its surface. The Chicle® models will have even less drag than your bare skin, since they’re totally smooth on the outside with 0% absorption factor.
    • It will compress on the way down and decompress on the way up in such a way that once you’ve balanced your weight-belt for the diving area and depth, you will realize that you’ll become a master of your own movements. It will allow you to sink like a stone on the way down and pop-up like a cork on the way up. That’s what I call a great freediving sensation!
    • It will insulate you from the freezing wind because it has fabric only on the outside, while inside the wetsuit you are dry, so this eliminates most of the unpleasant "wet-cold" sensation due to the water evaporation. The Picasso Chicle® wetsuits for example, eliminate the problem completely. If you are wearing Picasso Chicle® on a speeding boat, you could stand facing the wind for the entire duration of the ride and stay totally dry and warm.
    • It will stay clean and fresh and inhibit bacteria growth, because washing the odors away from a Picasso wetsuit will be almost as easy as washing it off a glassy surface material, especially if your Picasso wetsuit is a BioTermic.
