five units & plain units


Introducing Pre-loved

We aspire to contribute to a circular world, focusing our actions on this principle. This means prioritising the design, production and sale of trousers that people love to wear, season after season. Our vision is for Our Units trousers to never be discarded. 

When your trousers are ready to transition from loved to pre-loved, we will gladly buy them back for resale, breathing new life into unwanted items. 

Pre-loved is a concept whereby used trousers from Five Units and Plain Units can continue to be worn and cherished for years to come – because that's what they deserve.

Buy Pre-Loved trousers

Pre-loved trousers are ranked in three categories to simplify your shopping experience: 'Okay,' 'Good' and 'Like New.' All Pre-loved styles undergo thorough inspection before being offered for resale.

We accept Plain Units and Five Units trousers purchased after 1 January 2021, provided they are in good and wearable condition. Upon approval, you'll receive a €34 discount code for our website, regardless of which category they fall into.
