Size chart

 

 

 

 

 

 

 

How to use this chart:

Find your height and weight on the size chart. This will narrow you down to one or two different sizes.

Bibjohn: Find your waist and hip measurements in the chart for your gender. This is your Bibjohn size.

Pullover: Find your chest and waist measurements in the chart for your gender. This is your Pullover size.

OTHER FACTORS:

That you may find yourself in a different size top than bottom; it very common with T1 Wetsuits. It is very simple, imagine if you tried on two different sized one-piece wetsuits. You like the way the legs and hips feel on one of them, and you prefer the way the chest arms and shoulder feel on another. Simply put, this is what we offer combined with the notion that since the two pieces are not attached, but rather they overlap, there is a telescoping range between the bottom of the Pullover and the midsection of the Bibjohn to account for a larger range of heights and torso lengths!

So remember:

  1. It is not uncommon for the sizes of Pullover and Bibjohn to be different.
  2. If you are on the border of two sizes, and you are buying the Black Pearl Model, choose the larger of the two sizes.
  3. If you are on the border of two sizes, and you are an aggressive swimmer, choose the smaller size.

A Warning About Certain Lubricants and their Affect on Fabrics: Many athletic lubricants, especially non-liquid types, (like Body Glide, vaseline, and chamois creams) work well for wetsuits, but not well for clothing.  They tend to make clothing, especially loose clothing, sticky, instead of slick and slippery, and usually results in chafing. They will also damage, stain and discolor all fabrics over time.  We advise against using them, and their use will nullify our warranty.

The Speedtube™ was invented by Emilio De Soto in 2004. While he loved the benefits of swimming faster in a full wetsuit, he felt too warm and claustrophobic. After careful research and testing on how to achieve wetsuit buoyancy without losing speed, the Speedtube was born. The Speedtube floats the hips without sacrificing torso rotation and the natural stroke motion, resulting in better swimming technique. Perfect for racing, training or a replacement for your swim buoy.

Sizing : Please refer to the size chart button above for sizing guidance based on gender. If in doubt, email questions to contact@desotosport.com.

The Speedtube and all individual T1 Wetsuit pieces are completely legal under the rules set by ITU, WTC, USAT and all other governing bodies.  It can only be worn in races that permit wetsuits.

The two-piece design of the T1 Wetsuits offers more comfort and less restriction. Because the top and bottom are not attached, you have much more freedom of movement and there is no “torso-rubber stretch” or shoulder fatigue that occurs with one-piece wetsuits. All T1 models are sold as separates for a more customized and personal fit. With up to seven sizes of tops and bottoms, you have 49 possible size combinations from which to choose. Other features we innovated many years ago include lower necklines and thicker rubber in the legs and hips to help float the largest bones and muscles in the body. More floatation here means more speed. T1 Wetsuits are not filled with gimmicks, just physics.

New Features:

  • Less-toxic bonding agent for people with skin sensitivities

    Favorite Features Remain:

    • 5-panel contour design for an exceptional fit
    • Seams are glued and blind-stitched, making them more durable than the rubber itself
    • 5mm GreenGoma™ #8 Rubber with Super Composite Skin for maximum buoyancy without compromising speed
    • Shin cut high for easy fitting and removal
    • Heavy duty drawstring waist allows adjustability
    • Lined with 4-Way stretch Nylon Lycra® for comfort and to minimize chafing
    • Can be worn alone or with any First Wave or Black Pearl Pullovers and Vests
    • Sleek graphics, no gimmicks
    • Sold as separates for a truly customized fit

    • Chlorine resistant treatment, but not recommend for repeated use in chlorinated water

    Made for swimmers and triathletes who:

    • have a weak kick and want maximum hip flotation
    • overheat easily in other wetsuits
    PLEASE BE AWARE:  We created this bottom to avoid overheating in races where the water is warmer than 68 degrees. This is due to the water entering between the top and the bottom at the waist. There will likely be a separation between any top and the Speedtube, once you start swimming.  It does not cause any drag (if the drawcord is tightened) so you do not swim any slower.  So if you are looking for maximum warmth we recommend the Bibjohn.  If you are comfortable in cooler waters the Speedtube is amazing.

    A TIP FROM EMILIO:   The drawstring system is quite simple.  You just use a shoelace knot.  You then carefully leave tuck the two bows into the waist while leaving the two ends out.  When it comes time to untie it, you just reach down for the two ends and pull.


    Whether you like to swim for exercise or are on the swim course of a Triathlon, T1 Wetsuits offer you speed, comfort and buoyancy that will make swimming pure pleasure!

      So Easy!

      For a bigger guy like myself the speed tube has been a life saver. I get to the reservoir, throw it on with no effort, and hit the water as happy as a clam.

      Speedtube Great in Cold Sea Water

      Have been wearing them training in 61-64 degree water off the New England coast. I love the added flotation and speed. I barely need to kick (freestyle) as this wetsuit “reorients” the plane of my body making me more parallel to the ocean floor. My only concern is, due to the extra hefty neoprene gauge, I may get over-heated in warmer water temps….I have a 2 mile ocean swim next week across Narragansett Bay where the water temperature is predicted at 68 to 72*…but its already 69 currently. Over 72-73 degrees I may have to go to Plan B….but I still love this item!

      Perfect product for anyone who trains in the open water!

      I've been racing for 20+ years, and train exclusively in the open water during the summer, mostly solo in a lake. I've been using the speed tube for well over 10 years and it has never disappointed. Keeps me in the "wetsuit" position when a wetsuit would be way too hot for a 45-min swim in high-70 degree water. Not only is it comfortable, but its bulletproof durable! Before i "discovered" DeSoto wetsuits, I went through 4 or 5 full suits from other brands (team sponsorships.) The others all ended up tearing somewhere, or a zipper breaks, etc., even though I would only use the full suits once or twice a month for races. I've used the speed tube 3-4 times a week for many years! Early in the season i'll throw on the sleeveless or the full sleeve T1 top if the water temp is low. Those have all held up as well, as good as the day I bought them! Absolute genius invention and perfect product for anyone who consistently trains & races in open water. And oh by the way, if you ever have a product issue or question, the owner of the company will email you or call you -- Emilio stands by his products, and his devotion to quality, his customers, and to the sport, is obvious and evident.

      Two piece wetsuits are just what I needed and have used for over 10 years

      Great news for this older adult-onset swimmer. The 5mm thickness correctly aligns my body with high hips and legs. The two-piece suit means I never need help to get the wetsuit on. Older and less flexible shoulders don't care for messing around with those zip up one-piece wetsuits that normally require help from another person. Most of my weekend training swims at the state park beach area is done early in the am and by myself. Durability? I have a speed tube from 10 years ago that still functions as designed. I usually swim in the lake 8-10 times a month from Mid May to the end of September when the beaches close. That is nearly 400 swim sessions in my older speed tube.

      My most used neoprene product

      I love my speedtube! - Openwater swimming in decent warm water: A bit extra heating in water temperatures around 20 Celsius - gives the feeling of swimming without wetsuit, with extra security and speed as a full wetsuit. - Using it in "cold" pools and many water activities when it's a bit too cold with only the swimming trunk. (Playing with the kids in cold waters, SUP-board etc). After 15 years active use I need to buy a new one....

      Great product and awesome value

      I have been looking for a new wetsuit. I currently own a few high end one piece long sleeve and sleeveless, however I don’t like the tightness that they create in my shoulders, I feel like there is extra pressure due to my height (198cm and 110kgs). I thought I would try the T1 Speedtube long pants. I bought the size 7 and like the stretch and fit. I gave them a run today and dropped 10 sec per hundred from 1min 30sec to 1min 20sec per hundred. Next purchase will be the sleeveless vest. If you are not happy with the fit of your wetsuit I would definitely give DeSoto a try.

      Great Product

      I hate the restriction of a full suit on my swimming so I gave the speedtube a shot. It fit and worked great. I would recommend to any ocean swimmer who wants to add a little warmth and buoyancy to his/her swim.

      T1 Speedtube

      This is my second T1 Speedtube. I had one for years that I just eventually wore out, probably by letting the ocean water eat it away. There was no question that I was going to replace it with the same thing. I get plenty of lower body buoyancy, and plenty of warmth. I've worn this without anything on top through several winters in La Jolla, and it does the trick.

      Perfect

      I get extremely claustrophobic in a wetsuit and usually end up unable to breathe or wheezing. I’ve been wearing swim skins instead. I decided to give these a try to give myself the wetsuit edge most other triathletes have, and I couldn’t be happier. These provide the perfect leg flotation and balance with non of the concern for upper body constriction—and are MUCH faster to strip than a full suit. I’m so happy DeSoto provide a two piece option.

      great experience

      So, i’m one of those people that panics in wetsuits. In preparation for my first 70.3 Iron, I stumbled upon the speed tube and vest. WOW. It was fantastic. Swimming in the open water without any panicky thoughts, I simply didn’t think that was possible. Fast swim split, to boot! Next race is an Ironman, you can bet I’ll be wearing my speed tube and vest!

      T1 Speedtube

      Great! Other brands offer a product that was either too thin or were so low rise that they didn’t cover my bottom. Your Speedtube is perfect!
