Questions about payments and the method of payment:

The order page (completing order) is secured through https. The online payment is then securely handled by Payment Service Provider Mollie. Mollie makes online payments at Undiemeister® possible by offering online payment methods. They take care processing your transaction and check for fraud if necessary.

No, your credit card number is and remains invisible to us for safety and privacy reasons. Moreover, we have no need for it anyway.

All invoice payments are reviewed by Mollie, that’s outside our control. They use their own criteria, we have no influence on this at all.


A true Meister thinks of the well-being of our beautiful earth. That is why we want to limit the number of shipments where possible, we do so by encouraging larger orders. After all, one or two boxer shorts are never enough, especially if you know our incomparable premium quality! That is why we have moved the limit for free shipping to € 70,-. Below that order amount Undiemeister will charge € 3.95 (in Belgium this will be € 4.95). We charge this for the shipping and administrative handling of your order. Of course we will pay for any subsequent deliveries. Returns are at your own expense, but… we’ll pay for the shipment again if you want to exchange.

Password when ordering

This is a password that you come up with yourself, so one especially for Undiemeister, or a password that you already have for another use. Whatever you want

You can then log in to track your order. Moreover, the password makes it easy for you to order again the next time: you log in with your e-mail address and password and your (address) information will be filled in for you.

No, it’s invisible to us.

Yes, if you log in with your email address and your current password you will be taken to your customer section, here you are able to change the password.


Sure, take your time. We believe in slow fashion. Just picture more color boxer shorts and an increasing number of t-shirts


This is due to the unique combination of TENCEL™ with organic cotton and the optimally sustainable way in which both fabrics are produced. Recycling is of paramount importance to us, we throw away as little as possible and strive to be CO2 neutral. Because of this we also surpass bamboo boxer shorts (and we should know!).

Almost all of the fibers of which the yarn is spun come from Europe. This also applies to the place where our articles are assembled.

30 degrees, not too much cycles. Don’t steam. You are better off not using tumble dry and if you want to iron the shirt make sure you use a low temperature.

Mellowood® is prewashed and preshrunk. Shrinkage must therefore be minimal.


Same as everywhere else. Undamaged, unworn and in the original packaging.

Yes, but only if you return within 14 days and the items are undamaged. We will then refund the amount through Mollie as soon as possible, within 30 days at least.

Simple. Send your return to:

Undiemeister, Ambachtweg 22, 5731 AG Mierlo, The Netherlands.

Please add the exchange form which you can download on the page “Exchanges and returns”, at the bottom. Print it out and fill in what you would like to see happen. Please send the form to the above address. Unable to print for whatever reason? Then add separate information such as: order number, items in your return and what you would like to see happen. For example: which size you want, which color or that you are returning and want to be refunded. Please make sure that you meet the return conditions ok?

Yes, that automatically happens and will be sent to the e-mail address you have provided.

After receipt we will ship the new items as soon as possible. It almost always occurs that your order will be delivered the next day, except on Sundays.

Met hun eigen Mellowood-stof keert Undiemeister terug naar de natuur zonder in ontwikkeling achteruit te gaan. Sterker nog, dit ondergoed is een welkome sprong voorwaarts.

De administratie en logistiek zijn bij Undiemeister in goede handen. Maar wat belangrijker is, is de pasvorm en het materiaal van het ondergoed. Ik was verwend met bamboe ondergoed (Bamigo en Bamboo Basic) maar de stof die Undimeister gebruikt draagt nog veel fijner en ziet er dan ook nog erg goed uit. Ik ben er blij mee.

De mix van katoen en Tencel is perfect. Het is veel zachter dan alleen katoen en toch sterk. Ook is het beter voor het milieu dan puur katoen.

Geweldig ondergoed. Satijnzacht, blijft goed in model en mooie kleuren. Een goed vervolg op het Bamigo ondergoed.
