Meyer RIO Slim Fit Pima Cotton Trouser – 3116-16

$163.00 $89.00

Meyer RIO Slim Fit Pima Cotton Trouser – Style 3116-16 elevates everyday dressing with refined German tailoring and eco-conscious craftsmanship. Designed in Meyer’s modern RIO fit, these trousers feature a sharp, tapered silhouette that maps cleanly along the leg while ensuring complete freedom of movement.

Crafted from a luxury blend of 98% organic Pima bio cotton and 2% elastane, the cloth delivers a remarkably soft, breathable handle with micro-stretch performance. The long-staple organic Pima fibres ensure durability and colour fastness, while the integrated stretch allows natural flexibility that prevents bagging or sagging throughout long days.

The classic flat-front construction provides a streamlined waist profile that sits smoothly under light knitwear or blazers. Inside, the waistband is appointed with a colourful tropical botanical pocket lining, an internal French bearer button, and Meyer's signature stretch waist architecture for seated comfort.

Practical detailing includes slanted front side pockets with an integrated coin pocket, double-piped button-through rear pockets, and a polished metallic Meyer emblem on the back waist. Rendered in a seasonal airforce blue shade, these trousers transition effortlessly between office hours and evening celebrations.
