Products returned must be in new condition.
To accept a return, the product must be in new condition, ie, in the same condition as, for example, in-store you try a garment and decide not to buy it. Your return constitutes a fitting and the returned product must be in perfect condition.

Due to the nature of many of our products, you must, for reasons of hygiene, do the fitting over your underwear. We reserve the right not to credit the return fee if we find that the condition of your returned product is unsatisfactory.

To note; If you purchased your EC3D gear at one of our retailers, you will need to plan to return it to your retailer.




Contact us if, despite our vigilance, you receive a defective garment (a defect affecting the seams or fabric, for example). We will replace it at our cost. Obviously, wear resulting for improper use or abuse (see section on How to adjust your garment) is not covered by this guarantee.


The calibrated compression of EC3D garments is measured and tested on a regular basis. The results of our studies allow us to offer you a full guarantee on the compression required to meet targeted performance. If you feel that your garment no longer provides adequate compression, contact us within the required timeframe to discuss the possibility of replacing it.

Which size should i take if my measures are in 2-3 different sizes? Measuring every part of the body that is covered by the compression garment is paramount. For example, for a shorts, measure the circumference of the thighs, hips and waist. The greater measure between these three measures should dominate. When the measures overlap, you are at the greatest size of one size and the smallest of another. We recommend you take the larger one. Between each garment size there is 2 to 3 mmHg difference in compression. Which means that even if you opt for a smaller size you will not have too much compression and conversely you will always have enough compression to feel the effects if you take a larger size. Of course, it is always a matter of personal comfort.



Washing instructions
Machine wash on normal cycle
Do not tumble dry, hang to dry
Do not use fabric softener
Only oxygen / non-chlorine bleach allowed
Do not iron

To avoid any inconvenience, take care of your EC3D garment. Avoid premature fabric wear resulting from rubbing against equipment placed over the garment. Also ensure that the Velcro elements are closed before washing or storing the garment, otherwise you could damage the fabric.

How to put your garment?
Given our garments’ high degree of compression, we advise you to put them on with care. Keep your nails short and well filed, and avoid pulling on the seams when donning them. See the “How to adjust your garment” section for practical tips, which will help you fully appreciate your EC3D garment and enhance your performance.
