TWO-PIECE DESIGN: Means more comfort and less restriction. Because the top and bottom are not attached, changing your stroke is not necessary. We have eliminated the torso-rubber-stretch that causes shoulder restriction, and with it, the fatigue that occurs with traditional one-piece wetsuits. The different models of tops and bottoms are sold as separates so you can customize your fit and your performance needs.

PULLOVERS WITH ZIPPERS: Lightweight, custom-made zippers allow all Pullovers and Vest a more intuitive and faster removal.

LOW NECKLINE: This feature facilitates breathing, eliminating the "first timer's choking sensation," often accompanying one-piece suits. This feature makes it easier to turn your head to breathe and to raise your head to look forward. This also reduces chafing.

BIO-STROKE DESIGN: When lifting your arms, your shoulders rotate forward. A wetsuit should not inhibit this motion. The Bio-Stroke Design pulls the arms forward (resembling a mummy walking) and makes swimming less confining.

CORRECTS YOUR SWIMMING POSITION: The optimized hip flotation further lifts the hips and legs to put the body in the efficient "downhill" swimming position. We were the first wetsuit company to do so.

SPEED: The T1 Wetsuit has repeatedly been proven to be the fastest on the market. It is made with Yamamoto SCS Super Composite Skin, making it flexible, buoyant, and very fast to remove.

100% SATISFACTION GUARANTEE: Buy a T1 and test it for 15 days. If you do not find it to be the best wetsuit you have worn, return it for a complete refund. We encourage you to see if any other wetsuit company will offer you this guarantee. Then you can test any wetsuit against the T1!

The single difference between the First Wave and the Black Pearl is the type of the rubber. All other features remain the same: the fit, the construction, and the rubber thickness.

The First Wave is made of Yamamoto #39 and the Black Pearl is made of #38 rubber. Both are coated on the outside with Yamamoto SCS Super Composite Skin. The #39 rubber is more closed-cell and is slightly lighter in weight. Because of this, you float better. Also, the #39 rubber is a slightly more flexible; however this does not imply that the #38 is not flexible. The #38 is more flexible than the rubber used by many of our competitors. Combine that with the way our wetsuits are designed to fit, in addition to our new innovative zipper, and you likely have the best and second best wetsuit on the market.

Enter the Speedtube! The Speedtube is a wetsuit 3/4-length pant that ties at the waist and comes in either 2 mm (Speedtube 2) or 5 mm (Speedtube 5) thickness. Made of #38 Yamamoto SCS, the Speedtube can be worn alone or combined with any of the T1 tops. It is a great piece to wear in wetsuit-legal races, but the water is too warm for a full wetsuit. If you overheat easily, this is the perfect alternative to a fullsuit without losing the wetsuit-flotation advantage.

The Speedtube 5 is a great piece for open water swims or even pool training. It lifts the hips and allows for quality swims without losing torso rotation, which often occurs when wearing a pull buoy.

The Speedtube 2 is the perfect bottom for swimmers that have a strong kick and complain that wetsuits float the legs too much. De Soto Sports introduced the Speedtube to complement the 2007 T1 Wetsuit Collection by offering more functionality as well as more affordable price options.

How to measure:
CHEST (circumference measured at the nipple line) IF YOU ARE MALE

Please keep in mind that the size chart is a basic guide and every body is unique. We each know our own bodies and whether we are considered disproportional in any way based on garments we have bought in the past. If you have any doubts, please call us at 888-293-3934 or email us at sales@trisports.com.

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

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

Other factors: 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.

One of the strengths of a two-piece suit is the ability to mix-and-match tops and bottoms to come up with an appropriate fit. Even a top pro––man or woman––may find the size chart not entirely indicative of his or her body's idiosynchracies. One who comes from a strong cycling background and has muscular legs and a smaller upper body may fit into a different set of sizes than one who comes from swimming and has a large chest and back. Consider, when choosing the appropriate T1 sizes for you, whether you're evenly proportioned or whether you might need to stray from the recommended bibjohn and pullover sizes.
