GRS Certified Recycled Nylon

Our Casita Avoca Slide Tri is proudly GRS certified, giving you confidence that it is genuinely crafted from recycled fabrics. Every yarn can be traced back to verified sources such as plastic bottles, fishing nets, and reclaimed carpet fibres. No greenwashing, just a genuine commitment to creating quality swimwear that cares for the planet.

Oeko-tex® Certified

Our fabric mills employ state-of-the-art processes and printing methods, and our Casita Avoca Slide Tri conforms to Oeko-tex® Standard 100. This is an independent certification system that ensures textiles are produced free from harmful chemicals.

The Secret Within

To truly appreciate the quality of our swimwear, you only need to look within. Our Casita Avoca Slide Tri is fully lined with our bespoke lining, which is high in Elastane to sculpt and support. Seams are beautifully finished, usually enclosed, keeping overlocked edges out of sight.

Technical Mastery

With 30+ years of industry experience, this piece has been crafted with the utmost care and skill. The Casita Avoca Slide Tri is fully lined with silky, body-sculpting fabric and plenty of elastane for superior support. Every seam and internal element is carefully encased for comfort. Beautiful inside and out.

Built on Decades of Swimwear Mastery

Monte & Lou was never about chasing trends. It was built on a simple truth learned through decades in the swimwear industry: great swimwear is engineered, not improvised.

Every silhouette is refined through technical precision. Every detail is intentional. Luxurious, eco conscious fabrics are paired with expertly engineered cuts to deliver swimwear that flatters, supports, and feels exceptional on the body.

This is swimwear designed by authorities in the field. Crafted with confidence. Worn with confidence. Made to last, season after season.
