Why Buyers Choose This RPET Drawstring Bag

Premium Foldable & Lightweight Design

This RPET drawstring bag folds flat into a compact pouch that fits in a gym locker, car door, or suitcase. The ultra-light construction means users barely notice they are carrying it — until they need it.

• Folds into a small pouch for easy storage and travel
• Weighs under 80 grams — lighter than most water bottles
• Quick-fold design with no separate parts to lose

Eco-Friendly RPET Material

Made from post-consumer recycled plastic bottles, this bag delivers the durability of virgin polyester with a significantly lower carbon footprint. Therefore, it appeals to eco-conscious buyers in Europe and North America. For more details, read our RPET bag material guide to understand why recycled fabrics are increasingly specified.

• 100% post-consumer recycled polyester (RPET)
• Oeko-Tex 100 certified — safe for skin contact
• Machine washable at 30°C for repeated use
• Reduces plastic waste while promoting your brand

Waterproof & Reinforced Build

The water-repellent surface and reinforced stitching make this bag suitable for outdoor use. As a result, rain, sweat, and spills bead off the fabric rather than soaking through. In addition, the reinforced bottom corners prevent tearing even when the bag is fully loaded.

• Water-repellent PU coating protects gym gear and electronics
• Reinforced bottom corners prevent tearing under load
• Double-stitched drawstring eyelets for longevity

Spacious Capacity & Easy Access

Despite the compact folded size, this backpack holds a full set of gym clothes, shoes, and a water bottle. Furthermore, the wide mouth opening makes packing and unpacking effortless. Because of this design, users can access their gear quickly without digging through a narrow opening.

• Dimensions: 34 x 45 cm — fits standard gym locker contents
• Wide top opening for easy loading
• Internal pocket for keys, phone, or wallet

Adjustable Drawstring Closure

The thick braided drawstrings double as shoulder straps, distributing weight evenly across the back. Meanwhile, the cord-lock system prevents accidental opening during movement. Consequently, users can run, cycle, or hike without worrying about their belongings falling out.

• Thick braided cords — comfortable on shoulders, even when loaded
• Cord-lock system keeps contents secure during movement
• Can be worn as a backpack or carried by the top handle
