RATELWORKS Co., Ltd. (Headquarters: Higashiosaka City, Osaka Prefecture) will launch the "SEPARATE STUFF BAG / RWS0365," a highly durable stuff bag utilizing Ultra-High Molecular Weight Polyethylene (UHMWPE) fiber.

This product is a stuff bag designed to let you smartly organize and store items in situations where luggage tends to increase, such as camping, traveling, going to the gym, beach trips, and disaster preparedness.

While combining high durability and functionality, we pursued a design that naturally blends into everyday life.

Highly durable stuff bag utilizing Ultra-High Molecular Weight Polyethylene (UHMWPE) fiber.

Highly Durable Material: UHMWPE Fiber

High-performance outdoor material that blends into daily life.

Overwhelming strength within lightness.

We use "Ultra-High Molecular Weight Polyethylene (UHMWPE) fiber," which boasts top-class strength even among outdoor materials. The grid-woven fabric provides high abrasion resistance and tear strength while remaining flexible and lightweight. It delivers high performance in harsh environments and stylishly blends into everything from mountain climbing to daily life.

Peace of mind for rough handling.

Highly durable design for long-term use.

It is a material that is easy to handle in rushed situations, whether breaking down camp is imminent or it's stuffed full of children's belongings. Even if the fabric sustains damage, the structure prevents the tear from spreading easily, ensuring long-lasting, reliable use.

"Separate Structure" for Efficient Luggage Organization

Smartly separate and store wet/dirty items.

It adopts a hybrid structure combining highly breathable mesh fabric with PU-coated water-resistant and dust-resistant fabric, allowing for different uses depending on the purpose.

The mesh side prevents moisture and heat buildup, comfortably storing sweaty clothes, towels, or post-use changes of clothes. Since the contents are visible, finding items is easy, and it offers excellent visibility during packing.

On the other hand, the PU-coated side features a water-resistant and dust-resistant specification that can separately store wet swimsuits, dirty shoes, and sandy gear. By utilizing a water-resistant zipper, moisture and dirt transfer are mitigated.

Even when you want to quickly gather your belongings during pack-up, it can smartly organize "wet items," "dirty items," and "dry items," making it comfortable to use in various scenes like camping, traveling, the gym, and the beach.

It is not just a storage bag, but a stuff bag designed to make the actual organization of luggage comfortable.
