Adidas’ Defender 4 Small Duffel proves sustainability doesn’t sacrifice performance. Made with 50% recycled materials, this 40L bag carries essentials without excess bulk. The tapered design fits snugly in narrow gym lockers while the wide mouth opening provides easy access to contents.

A detachable shoulder strap converts between handheld and crossbody carry modes. The front zip pocket organizes keys, cards, and small accessories, and the minimalist construction means fewer failure points over time. Despite its eco-focus, the fabric maintains water resistance comparable to virgin polyester.

Ideal for yoga practitioners or those with light packing needs, this bag transitions seamlessly from studio to café. Adidas’ Primegreen label ensures it meets stringent environmental standards without premium pricing. The clean three-stripe design appeals to those who dislike overly technical aesthetics.
