The First Wave provides ultimate comfort and eliminates restrictions often found in one-piece wetsuits. This is why the T1 First Wave is a triathlete's First Choice!

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 two-piece design of the T1 Wetsuits offers more comfort and less restriction. The top and bottom are not attached. This means 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 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:

  • Zipper is lighter weight and corrosion resistant
  • Less-toxic bonding agent for people with skin sensitivities
  • Interior 4-way stretch nylon-spandex has a higher thread count than any other brand for more stretch and durability, faster drying, and to minimize chafing.

Favorite Features Remain:

  • Stretchy 5mm thick rubber starts at the ankles, goes up to the crotch and around the sides of the hips to float the legs and hips more than any other wetsuit.
  • Low profile 2mm Bib straps with soft Lycra trim go over the trapezius (base of neck) to allow unrestricted reach, prevents tired shoulders, and aids in faster swim times
  • GreenGoma™ #9 Rubber with Super Composite Skin makes the First Wave the warmest, fastest, most durable, flexible, buoyant, and the most comfortable wetsuit in the world today.
  • Angled leg openings for faster and easy removal
  • Longer seam tape for self-customizing leg length
  • Seams are glued and blind-stitched, making them more durable than the rubber itself
  • 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.

The Bibjohn is 5mm thick from the oval ankle openings up to the crotch and up the sides of the hips. From that seam up, the Bibjohn is 2mm thick. This includes the midsection around the stomach, low back, as well as the bib straps that extends up the spine in back and up the chest in front. It is designed this way so when you wear any of our T1 tops, the total rubber thickness remains less than 5mm thick. You have all the needed flexibility while still keeping your spine and vital organs warm. The total thickness also adheres to all rulings from all national and international governing organizations that limit the maximum wetsuit thickness to 5mm.

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!

Wow!

Sorry for the lag in providing a review but today was my first race (Sandpoint, ID Long Bridge Swim) with the new DeSoto T1 First Wave Bib John and First Wave Concept 5 pullover. 6th out of 22 in the 65-69 old guys group. My time would have won a couple years ago but we had some fast old guys today! First off, by far the most comfortable wetsuit I have ever used. Why all suits don't have a zipper that pulls down for closing is baffling. So much easier to put on, can't pop open like some of the pull-up ones, and really ez to remove.Time-wise I was almost exactly 10 minutes faster for the same distance as I was in the 1/2 IM just over a month ago. Buoyancy is superb. I am 6'5" and 190lb-ish so tend to float like a steel pipe. The DeSoto made it feel like half my body was above the water line. Other than just trying it on, I had zero time in the water until today so quite happy with the result. I did not have that constriction feeling around my chest as with my previous suit even though I had sized up in it (previous suit). Your sizing recommendation was also spot on. Olympic IM coming up end of August and the full IM in Penticton in August 2020 so looking forward to more time in the DeSoto! .

Excited to try this on!!!

I have not used it yet, my first swimming session will be on 05/05. But I am very satisfied with the overall construction quality of this product, Emilio has thought of all the details to make it of a great quality, and I am sure that it will perform accordingly!!!

Great customer service.

Before ordering the T1 First Wave BibJohn & Concept 5, I had emailed DeSoto asking a few questions (including sizing) and received answers fast. Very helpful explanations. I have not swam in them yet but have tried them on at home and they seem to fit very well.

First Wave, First Class

In order to fairly and properly assess this wetsuit, I waited until the end of a full season of use to write this review. But, to be honest, I knew exactly what I was going to say after my very first race in the T1 First Wave. Buoyant, flexible, fast. The suppleness of the material combined with the 2-piece design allows for an almost completely unhindered swim stroke. I have always had sore, swollen shoulders after a wetsuit swim, which compromises my comfort on the bike in the aero position. Not with the First Wave, the difference is astounding. Of course, the T1 is just as fast as it is comfortable. Definitely right up there with the other top tier wetsuits. I really don�۪t see myself wearing a 1-piece suit ever again. As long as De Soto is making this product, I�۪ll be buying!

The size chart above should serve as a general guide. If you would like assistance in determining the proper size, please send the following information to contact@desotosport.com.

WEIGHT - Accuracy helps us provide a more accurate size for you.
CHEST - Fullest part of breast, measured as the largest part of circumference right over the pectoral muscle.
WAIST -  Circumference measured at the belly-button line - this is NOT the same as your pants waist size.
HIPS - Circumference measured at the widest point, NOT at your hips where your belt may go. Typically this will measure just a few inches below your hip bones and around the largest part of the glutes.

 

If you do not have a tape measure and you need something to measure with, use a belt, or smart phone power cord, and a ruler.
