Product Insights
The Birkenstock x Tekla Hopper Stripes Poplin Pyjama Short, an exclusive Simons collaboration and Birkenstock's first apparel venture, redefines loungewear as daywear with a no-rub elastic waistband, practical pockets, and a high-rise, wide-leg silhouette in GOTS-certified organic cotton poplin made in Portugal. Priced at 195 CAD—significantly less than Tekla’s mainline—it offers true-to-size fit for waists 25–35 inches, a sand color that pairs with earth tones and lightens with washing, and durability that develops a patina, though shrinkage requires cold washing and low drying. Balancing between sleep and street wear, these shorts deliver a structured, oversized drape that prevents a sloppy look while emphasizing ethical production and a Tokyo-inspired city-to-home narrative.
