The technology of champions, for all swimmers
Extra-flexible knitted fabric
Superior knitted fabrics have been augmented in the ST 2.0 with an extra durable lining to provide outstanding stretch, optimal compression and total freedom of movement. The result is a high-performance suit that minimizes surface drag for exceptional hydrodynamics, and offers unrestricted movement without compromising key muscle support.
Greater support and compression
The new lining brings added technical functionality to the ST 2.0 range. Incorporated into the top front of both the full suit and the jammer, and extending down the back of the leg, the lining provides greater muscle compression for targeted areas, and improves core and leg support, allowing the swimmer to stay stable and strong in the water.
Better comfort and durability
The ST 2.0’s shoulder structure features a new design with extra reinforcement in the centre strap. Bolstered by the shell fabric and durable lining, the shoulder strap provides greater support in the shoulders and upper back, enhances the overall fit and feel of the suit, and adds an extra level of durability.
Ergonomic construction
In the ST 2.0, the seams have been moved to deliver greater ergonomic qualities, helping with body and leg lift and positioning, while also offering unrestricted biomechanical movement. In addition, flatlock construction of the seams contributes to the suit’s perfect fit, with the seams sitting snugly against the body to help keep optimum shape in the water.
Choose the right size
The fit of a swimsuit should be based upon your individual needs and preferences. This size guide refers to competition suits, which are designed to fit the body tightly, in order to provide superior muscle compression. These suits are designed to be worn for short lengths of time, and therefore if you wish to train in one, for your comfort we recommend purchasing a larger size.
HOW TO TAKE MEASUREMENTS
A · Chest: Take the measurement over the fullest part of your bust.
B · Waist: Measure around the narrowest part of your waistline.
C · Hips: Measure around the fullest part of your hips.
D · Torso loop: In a loop, measure from the highest part of the shoulder, beneath the crotch and then back to the starting point.
(**) Body measurements and corresponding sizes are to be considered as a general guideline. We strongly recommend that any racing suit should be tried on by each swimmer before choosing the appropriate size, based upon individual preference in terms of compression. Swimming stroke and distance may also be key factors in the suit selection.

Honestly, I wonder if anyone is expecting something new here, the powerskin is a brilliant material that's FINA approved; you suppose to use it for races, however, competitive squads, as my kids are using it on daily training and keep Carbon for races ...They use this suits for long races (400meter and above) to give them flexibility and tight to push for extra miles...I bought the same material for my boy also, and we have been using it for 3 kids for the past 7 yearsHighly recommend it..

On the approved tech suit list for under 12 age group swimmers. Relatively easy to put on...as tech suits go. Relatively comfortable...our swimmer wears it through the whole meet...no need to take off between events. Have used an identical one in eight meets to date...with no obvious loss of function...durability seems to be within expectations...wanted a spare.

Bought this for my 9 yr old. The color is as vibrant as you would imagine but it appears to be cut a bit smaller than the average 26 and therefore fits more like the 24.

This product does sizing is extremely off! We ordered according to the measurements and it was so small that my swimmer couldn’t even get it on all the way.

My daughter’s old tech suit was used longer than it should have been. We seen this while on Amazon while at a meet and bought it right away. I would definitely by from this seller again.
