Undyz has a few things that set us apart from anyone and everyone else.

1) Are gap between sizes is smaller than anyone. That's why you might be a XL in traditional underwear but find yourself in a 2XL or even 3XL in ours. We base our sizes on true measurements so that you get

a tailored fit.

2) Our patented InnerWall System has premium fabric walls that separate the inner legs and the family jewels. These walls stay put which means that there is never an opportunity for skin-on-skin contact which is a source of a lot of men's underwear issues.

3) We only use the highest quality fabrics, threads, and stitching techniques to ensure durability, comfort, and consistency. Our 95% Modal / 5% Spandex blend guarantees you that no toxic chemicals or plastics will go anywhere near your groin.

Modal is a fiber made from Beech trees. The fabric is extremely smooth and soft. It's unbelievably breathable and durable. The important thing to note about Modal is that it is better than cotton in almost every way.

Choosing the right size is going to be the most time-consuming part of your initial purchase. We do no use jean sizing to select your Undyz size. Since or margin between sizes is much smaller than other brands, we've opted to use real, true, and accurate measurements of the body to ensure you get a perfectly tailored fit. Measure once, feel the difference.

Measuring your waist and your upper thigh (between the valuables and the inner leg), is all you need to make sure everything fits and moves perfectly with you.

Undyz will hold up is some pretty harsh "college laundry" conditions.

However, your Undyz will last the longest and stay soft and comfy longer when you follow our care instructions:

Wash in luke warm or cold water. do not use bleech, and wash separately from heavily soiled clothes. Tuble dry on low - medium low. High heat will cause the waistband to fail long before the fabric breaks down. You can also hang dry your undergarment, but who has patience for that?

We want to make sure that you love your Undyz. We want to make sure that you are sized perfectly.

That being said, we ask that you measure before you buy. If your Undyz arrive and they are not perfect, we will ask a few questions and process an exchange for the cost of shipping.

If you don't like your Undyz and you don't plan on buying them again, we will issue a full refund.

We may ask a few questions about your experience and about the garment itself.
