The two-piece design of the T1 Wetsuits offer 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.

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

New Features:

  • Zipper is lighter weight and corrosion resistant
  • Less-toxic bonding agent for people with skin sensitivities

    Carry Over Features:

    • 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 Yamamoto SCS™ (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 true customized fit
    • Sustainability is extremely important to De Soto, click here to learn how we are making a difference
    • T1 Wetsuits 100% Satisfaction Guarantee 
    • T1 Wetsuit product care and FAQs
    • 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

    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. 

    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!

    Awesome. Easy in and out. If your a strong puller these are great and also great for acceleration kicks.

    Added Speedtube to my arsenal

    Previously purchased a Black Pearl Pullover and Black Pearl Bibjohn. Great combo. Fast. Unrestricted shoulder movement. Can mix sizes (I’m a 4 top and 5 bottom). Maybe a little too hot for not-so-cold water. Purchased the Speedtube and Speedvest for training in Lake Michigan when the water temp is 70-ish. Super easy to get in and out of, doesn’t take up a lot of room in my bag, and I’m not cold on the beach when I finish a long swim. (I’m a swimming wimp when it comes to cold water.) And it still has great leg-float. So, now I have a lot of wetsuit flexibility – Black Pearl for less than 65 degrees, Speed for 65 to 75. Anything above that, I’m probably not going to use a wetsuit (for training). But I still use the Black Pearl for all races simply because it’s fast.

    Speedtube Purchase

    The Speedtube Wetsuit pant is beyond excellent, and fits my needs to a T. The timely personal attention and advice I received to help me make the purchase exceeded expectations. I will ONLY be working with DeSoto from here on out!
