Introducing Our USA-Made Wetsuits: Crafted One at a Time

This product is made-to-order and does not qualify for any discounts.

With global tariffs and ongoing trade uncertainty, our wetsuit import costs have more than doubled—making it unsustainable to continue sourcing from our trusted partner factory in Asia.

As a solution, we’ve begun producing Made-to-Order wetsuits right here in our San Diego factory. Each wetsuit is hand-cut, glued, bonded, and blind-stitched from start to finish by a single skilled craftsperson. Every suit is then carefully inspected by another team member to ensure the highest standard of quality.

We’ve made a few upgrades along the way:

The pullover is made with 3mm GreenGoma rubber—a bit thicker than our traditional 2mm—for added warmth without compromising flexibility.
The bibjohn features 5mm GreenGoma rubber with a slightly different outer skin from the pullover. It is a more durable thickness and helps your kick slip through the water more efficiently.

We began prototyping this concept about six months ago, testing it first in a pool, then a lake, and finally in open water and surf here in San Diego. That extra millimeter delivers noticeable warmth and buoyancy—making it faster without sacrificing flexibility.

We’ve already delivered these suits to customers, and the early feedback has been outstanding.

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.

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.

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

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!
