Thalassa Waterproof Backpack 40 L Black – Rugged and Floating Gear

Waterproof backpack for reliable gear protection

The Thalassa 40L by MARINE BUSINESS is designed for outdoor activities where moisture protection is essential. Its 40L capacity provides ample storage for clothing, electronics, and supplies, while the barrel-style structure ensures the bag remains stable during transport. It serves as a robust solution for kayaking, hiking, and marine environments.

Technical protection and watertight closure

Engineered for total protection, the bag utilizes a roll-top closure system. When rolled at least three times with trapped air, the waterproof backpack is designed to stay afloat. The exterior features bonded zips and heat-welded seams to prevent water ingress. For sensitive electronics, the use of an additional inner waterproof pouch is recommended.

Material composition and rugged construction

Built for demanding conditions, the backpack is manufactured from 500D PVC tarpaulin with a 0.5 mm thickness. This material choice offers high resistance to UV rays, abrasions, and dirt. The rugged gear bag design maintains its integrity in dynamic outdoor settings, ensuring long-term utility in wet or rainy environments.

Comfort and versatile transport system

The carrying system features adjustable, removable padded shoulder straps, allowing the bag to function as a trekking backpack. For manual transport or securing the unit to boats and kayaks, the reinforced side handles provide reliable attachment points. The design focuses on functional ergonomics for active users.

Recommended use

This floating gear bag is ideal for kayaking, camping, and travel. It is specifically suited for users who require a durable dry bag to keep supplies safe from water exposure during marine or rainy outdoor excursions.
