Frequently Asked Questions

What is the delivery time?
Orders placed before 23:59 are shipped the same day. The delivery time for the UK and Ireland is 3-5 working days. As soon as the order has been placed you will receive an e-mail with a track-and-trace code.
Which size should I order
Choose the size you would normally choose or use the size charts on our product page. The Fibershirts and boxers have a normal fit. With a slight stretch they fit perfectly to your body. The socks are one-size-fits-all.
Are the products in discreet packaging on delivery?
Our products are always discreetly packed. Nowhere on the packaging is it mentioned that it contains anti-sweat clothing
How can I return my order?
Orders can be returned to the shipping address. This is possible within 14 days of receiving the shirt, provided the original label (+ hangtag) is still attached, undamaged, unworn, and in original condition. The return shipping costs are at your expense. The purchase amount will then be refunded within 7 working days of receipt. PLEASE NOTE: The boxers and socks cannot be returned once worn, opened, and/or when the labels have been removed.
What is the best way to wash your clothes
We recommend washing the T-shirts, socks, and boxers inside out at a low temperature. Hang dry them in the sun, not in the dryer! Do not bleach and do not iron.
What material are Fibershirts made of?
Fiber shirts consist of 95% MicroModal® fibers and 5% spandex. This material is silky soft and cooling to the skin. MicroModal® is completely CO2-neutral and sustainably produced. The armpit pads consist of 3 layers, of which the middle one is water resistant.
Do the armpit pads really work?
YES - We guarantee that Fibershirts will protect you from sweat stains. The water-resistant layer incorporated into the armpit pad stops every drop of sweat. Not satisfied = money back.
Do Fibershirts also help against sweat in places other than the armpit?
Due to the cooling, absorbent, and light material, sweat spots will be less visible. However, the waterproof armpit pads are exclusively designed for sweat spots under the armpits.
Do Fibershirts also protect against a sweat odour?
YES - No more stinky sweat odour thanks to our SILVADUR™ technology. This is a special silver treatment that kills 99.9% of all odour-causing bacteria. This allows you to wear Fibershirts and dress shirts multiple times.
Can I put the T-shirts, boxers, and socks in the dryer?
We recommend hanging our clothes or letting them dry in the sun. If this is not an option, then use the dryer at a very low temperature.
