ROCK CLOUD Dry Bag Waterproof Roll-Top, Blue, 20L — Ripstop Tarpaulin with Welded Seams

ROCK CLOUD 20L Dry Bag is a roll-top waterproof sack built from ripstop tarpaulin to keep clothes, electronics and gear dry during kayaking, rafting, beach trips and outdoor travel.

Lightweight yet rugged, this 20-liter dry sack uses a welded-seam construction and a secure roll-top closure to shield belongings from water, sand, snow and mud. It’s designed to be easy to clean, simple to pack, and versatile enough for a broad range of water and land activities. The packable size fits most day-trip loads and pairs with adjustable shoulder straps for carrying comfort.

How does the roll-top closure keep items dry?

The roll-top system seals the opening by folding the top several times and fastening the buckle, creating a tight barrier against water intrusion. It’s a mechanical seal—no zippers or seams at the opening—to reduce leak points and allow quick securement.

• Fold top 3–5 times and clip buckle for a watertight seal
• Wide-mouth opening for fast loading and unloading
• No external zippers that can let water in
• Simple one-handed operation when wet or gloved

What makes the material durable for outdoor use?

The bag is constructed from ripstop tarpaulin with reinforced welded seams, which resists punctures, tears and abrasion from rocks or brush. Its smooth surface wipes clean easily, so you can remove sand, mud or saltwater with a damp cloth.

• Ripstop tarpaulin body for tear resistance
• Welded seams to reduce seam failure under stress
• Easy-clean finish for quick maintenance after trips
• Designed for repeated use across seasons

How do the straps and sizes suit different activities?

This 20L model includes two adjustable, removable shoulder straps so you can carry it like a sling or attach it as a backpack-style pack. ROCK CLOUD offers multiple capacities—5L, 10L, 20L, 30L and 40L—so you can choose a size that matches day trips, multi-person outings or heavy-load adventures.

• 20L includes two adjustable removable straps for comfortable carrying
• Smaller sizes (5L/10L) use a single strap for light loads
• 40L model features thickened backpack-style straps for heavy gear
• Interchangeable straps let you configure carry style on the fly

Is the dry bag suitable for all wet-weather activities?

The bag is ideal for activities where you need reliable protection from splashes, rain, sand and brief immersion—such as kayaking, rafting, boating, beach outings, canoeing, fishing, hiking and skiing. It is not designed for sustained underwater use or deep submersion like scuba diving.

• Perfect for shorelines, decks, inflatables and whitewater splashes
• Protects electronics, clothing and food from moisture and grit
• Not intended for prolonged underwater exposure
• Use inside sealed cases for valuables needing absolute submersion protection
