Size guide
Orca sizes by chest, height and weight. When in doubt, go by chest. Questions? Ask us before you buy.
Thanks to the high elasticity of the materials, the more flexible wetsuits adapt better to the swimmer’s body than those with less elasticity.
If you’re choosing a wetsuit with less flexibility, you should select a size that fits well to your body.
We always recommend trying the wetsuit on to make sure that the fit feels right. However, should you have any questions, contact us and we’ll be happy to help you.
When selecting the ideal wetsuit size, three measurements should be taken into account: chest circumference, height and weight. When in doubt, we recommend choosing the size that best fits your chest circumference, since it is important that the wetsuit is well- fitted in this area.

To determine the ideal size of a two-piece wetsuit, four measurements should be taken into account: chest circumference, waist, height and weight.
The chest circumference, height and weight help to figure out which size top will fit best. When in doubt, the chest circumference should be the most closely fitted.

HIRU tops have 3 types of fits.
For the best jersey fit, take your measurements based on the diagram and compare your results with the following table.
When deciding on a size, please consider that our apparel fits snug, so we recommend ordering at least one size up if your body measurements are borderline or between sizes.
HIRU designs each product to adapt differently and take advantage of the intrinsic characteristics of the fabrics and materials used in each one.
By following these simple steps, you will find the right shorts for racing, training or leisure rides. Adjust both the bottom and the straps snugly to the body so there are no wrinkles. You’ll experience a light, sticky feel.
Simulate a bike position for a few seconds and check for adequate mobility, then try pinching the fabric in the thigh area. If the fabric returns to its original position upon release, then it’s the right size.
Conversely, if you feel rubbing or constriction, or the seams or straps are too tight, try a larger size. The straps, the elastic bands or the lower part of the leg tend to roll up but can be easily returned to their place with a few small gestures.
The short’s fabric is designed to provide a slight compression effect, and it’s only effective if the fabric remains close to the body.

About this product
This combination of innovative technologies makes the new Alpha the most elastic wetsuit on the market. The obvious choice for Natural Swimmers, those who have a background in swimming and have a good swimming technique. Focus on what really matters: Swimming without limitations.
Maximum Flexibility
The combination of 0.88 material and Yamamoto 44 neoprene provides maximum flexibility, ensuring greater stroke distance.
Hydrodynamics
The Nano SCS coating will minimize water resistance as you glide through the water, improving your hydrodynamics and performance with each stroke.
Decreased Buoyancy
Because of the use of thinner and more elastic materials, this wetsuit will help you maintain a more neutral and correct position for longer.
More Freedom of Movement
The reduced buoyancy and the use of a shorter reversible zipper offer full freedom of movement, so that the wetsuit feels like a second skin.
