Do the boxer briefs ride up?

To prevent the underwear from riding up during wear, we extended the length of underwear during the development process. The added length increases friction and has been very effective in relieving this issue. This solution has been confirmed and supported through the extremely positive feedback from our 100+ trial test customers with a wide range of body types.

How many washes can the antibacterial properties of the underwear last?

The silver fibre will not deteriorate after washing as the silver is permanently bonded to the fabric. The antibacterial property of the silver remains active even after being washed 245 times.

How does your underwear compare to its competitors? (Eg. Y Athletics & MyPakage)

All of our current KOY GEAR boxer briefs have a patented air mesh panel design that allows for added breathability and air flow. 


The Silver Air underwear from Y Athletics do not have this feature. However, the fabric for "Silver Air" is made from Merino wool which is similar to our modal fabric in its softness and breathability. Silver Air underwear also contains silver fibre.Everyday 0.3 grams of feces is left on underwear due to daily usage, yet Y Athletics Silver Air advertises not washing their underwear. We do not believe in this philosophy. As a result, our underwear is designed to be durable enough to be cleaned constantly without ever fading. 


As for "MyPakage" their Keyhole comfort technology is a good design and allows for ample room in the underwear (we don’t have that). They also use modal fibres in certain lines of their underwear. The difference is that KOY GEAR focuses on the application of material science and technology to fabric. The silver fibre embedded in our underwear kills 99% of bacteria. In addition, KOY GEAR briefs have a patented air mesh panel design that allows for added breathability and air flow.

If water makes silver dissolve, how does washing the underwear affect the effectiveness of the material/product?

Oxygen or moisture can cause the silver atom on the surface to be oxidized, forming the positively charged silver ion, which dissolved in water that kills the negatively charged bacteria. However, the metallic silver itself is water-insoluble. Washing does cause oxidation within the silver pouch, but since silver is one of the most stable elements, it would take years upon years for the whole silver fibre component to oxidize. Underwear is not meant to last a lifetime and even if it could, we would still recommend men to replace a pair of underwear generally every 5-6 months for health purposes. 

What are the KOY GEAR Boxer Briefs made from?

Modal: 37.5% 

Polyester (Air Mesh): 10% 

Polyester (Silver fibre): 10% 

Cotton: 37.5% 

Elastane: 5%

Are silver fibres only in the pouch at the front, or is it all over the underwear?

The silver fibres are only located in the frontal pouch. The reason why we are not integrating silver into the whole underwear is that the metallic property of silver fibre will make the fabric susceptible to ripping and stretching. To get the best protection while maintaining durability, we have decided to focus all the silver fibre into the pouch.
