Our Units design trousers for a better future.


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 unused 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

We believe in prolonging the lifespan of unused items, saving valuable resources instead of simply throwing them away. 

Pre-loved lets you trade-in and purchase trousers that are no longer used, contributing to a circular economy.

How does Pre-loved work?

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.


Visibly signs of wear, but in good condition.

A used pair of trousers in this category are worn/slightly worn but still well-maintained. Trousers have visible signs of use, such as minor defects, small stains etc.


Used, but in excellent condition.

A used pair of trousers in this category is only slightly worn and very well-maintained. Trousers display minimal signs of use, including but not limited to very small stains. 

Like New

As good as new

A used pair of trousers in this category has no defects or visible signs of wear and tear.
