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!

    Wetsuit top and bottom

    Good wetsuit. Have bought several T1s in a row now. Only complaint is that they only last me two years, while my friends’ last longer. Wanted to ask if, perhaps, I need to switch the sizes. Tried to contact you, but could not get through. No one available. So, good product, poor customer service.

    My favorite wetsuit.

    Always like the Desoto T1 wetsuits. He two piece works well for me. More flexible and suits my longer torso and short legs. Great customer service as always.

    Love this wetsuit

    15 years ago my husband bought me my first T1 wetsuit which really helped my swims and transitions as an Elite Triathlete. I LOVED the fit - comfortable around the neck/arms and easy to get off. I was sad that after many years of use I had a few holes on the arm/legs (not many I might add) so bought a new one - wow, extra comfort and great fit with new material used in the T1. Get one if you love swimming in the outdoors and/or compete in triathlons!

    Best Wetsuit available

    I have been using the De Soto T1 wetsuit since the first version came out and this is number 4. Emilio continues to improve these at every version. I've come out of the water either first or second when wearing this suit. It is just exceptional!

    First replacement in 6 years

    Still the only wetsuit worth owning. Nothing else has the ease of movement or quality of manufacture.

    Best Wetsuit Ever

    I've been using DeSoto wetsuits for over fifteen years. Time and hard use takes it's toll, so a new Bibjohn was in order. No restriction on arms. SWEET.

    T1 wetsuit

    T1 is definitely water tight. An excellent fit, very comfortable you glide through the water.

    Awesome wetsuit for age groupers

    Been racing for 6 years and was generally very pleased with my Aquaman Bionik suit. It’s a great high quality suit. However, the T1 First Wave is in an entirely different class. It’s basically perfect. It doesn’t ride up in the crotch, the arms structure is great for weaker swimmers like me, getting it on before the race is amazingly easy, and getting it off in T1 is shockingly amazing. I don’t think I’ll ever go back to a one piece suit again. Thanks again Emilio and team for crafting such wonderful tri gear.

    Exquisite Bibjohn

    This was my fourth Bibjohn and easily the best I’ve ever used. Super easy to pull on and off and excellent balanced floatation. Keeps me warm for my cold ocean swims.

    T1 First Wave Bibjohn

    Absolutely fabulous! I’ve only been able to test swim in a pool so far. However, paired with my T1 Pullover or my T1 Speedvest the T1First Wave Bibjohn is the finest wetsuit I’ve ever worn, and I’ve owned or tested most! The combo allows for excellent flexibility and a full, easy stroke. Another strength is fast removal. With a little practice removal is swift. I should also mention the easy sizing when buying DSS two piece suits. Two pieces allow a more customized fit. I was concerned about the shoulder straps causing chafing after trying it on dry and bare when it arrived. However, with a race kit on in the water I couldn’t tell the straps were even there. Getcha one!

    Flexible and Comfortable

    I have swum in DeSoto’s Black Pearl suit for two years and the Bib John and top were fine but felt a little constraining. I upgraded to the First Wave model and the high quality Yamamoto neoprene makes a significant difference in flexibility and comfort. I have tried several one piece suits and none offers the fit of DeSoto; I’m 6’4” and 175 lbs. when winter comes with 45F water I’ll add the Speed Vest under for extra warmth. Happy with DeSoto products.
