1. A Thin, Waterproof Stuff Sack for Everyday and Outdoor Use

A lightweight, portable waterproof stuff sack has been introduced as a new variant of BELLEMOND’s popular dry bags.

It can be used to protect contents from rain and splashes, or to separate wet towels and clothing.

From BELLEMOND’s best-selling dry bags comes a lighter, thinner, and more portable version: the Waterproof Stuff Sack. It’s perfect for travel, onsen, gym, pool, rainy-day outings, hiking, and camping—any situation where you want to keep wet, sweaty, or dirty items separated from the rest of your belongings.

2. For When You Don’t Want to Toss Wet, Sweaty, or Dirty Items Directly into Your Bag

Ideal for organizing clothes during travel, storing wet towels after an onsen, or carrying gym and pool gear.

After a hot spring visit, wet towels; after swimming, damp swimsuits; after the gym, sweaty clothes; on rainy days, wet raincoats—there are surprisingly many items you’d rather not mix with your other belongings. With the Waterproof Stuff Sack, you can reduce daily discomfort while keeping your bag neatly organized.

3. Choose from 2L, 4L, 8L, and a Compact Pouch

Select the right size—2L, 4L, or 8L—based on your needs, perfect for storing small items, towels, spare clothes, or rain gear.

The set includes three sizes (2L, 4L, 8L) and a small pouch, allowing flexible use depending on what you’re carrying—small accessories, towels, change of clothes, or rainwear. The entire set weighs only about 101g, and when not in use, the sacks can be folded down small, making them easy to store in travel bags or backpacks.

※ The small pouch is included only with the 3-size set.

4. Waterproof Fabric with 5,000mm Water Resistance

Features waterproof fabric with a 5,000mm water resistance rating. The exterior is silicone-coated, and the interior is PU-coated.

The material is 20D nylon, with a silicone coating on the surface and a PU coating on the reverse. Additionally, seam-taped construction ensures reliable water resistance, making it suitable even in rainy or splash-prone conditions.

※ Not fully waterproof. For best results, fold the opening over at least three times and securely fasten the buckle before use.

5. Subtle Mist-Tone Color Options

Available in Mist Gray, Mist Black, and Mist Blue—subdued colors that blend easily into daily life.

Colors include practical Mist Gray and Mist Black, plus a soft, refreshing Mist Blue. The palette is designed to feel at home in everyday settings without looking too rugged or outdoorsy.
