Product Highlights

Sonic Welded Waterproof Dry Sack 30L

Welded Seam Construction: The bag is assembled with high-frequency RF welding instead of stitching, leaving zero needle holes at the seams. This welded construction delivers true waterproofing that sewn bags cannot match.
Roll-Top Airtight Seal: Fold the top three times and clip the buckle: the roll-top closure forms an airtight, watertight seal, keeping contents dry in heavy rain, splashes, or short-term submersion.
Heavy-Duty Waterproof Fabric: Made from PVC, a thick, tear-resistant and puncture-proof material engineered for tough outdoor conditions.
Versatile Outdoor Use: Ideal for kayaking, boating, beach days, hiking, fishing and travel — perfect for keeping clothes, electronics, towels and valuables dry.
Comfortable Carry Options: Equipped with an adjustable shoulder strap and sturdy handles for crossbody, shoulder or hand carry.
Fully Customizable: Choose your colors, capacity, material and logo. MOQ-friendly with free sample service for OEM/ODM buyers.
