Packing Cubes vs Dry Bags: Which Keeps Gear Safer?

Quick Answer

If your priority is keeping gear dry in wet conditions, choose a dry bag backpack like the Big River Dry Backpack. If you need organization and quick access while keeping dust and light moisture out, packing cubes like the Hydraulic Packing Cube are the better fit.

Water Resistance vs. Organization

The core difference comes down to what you're protecting against. Dry bags are built to keep water out entirely, using welded or rolled closures and waterproof fabrics. Packing cubes, on the other hand, focus on keeping your gear organized and separated, with water resistance as a bonus rather than the main job.

For kayaking, rafting, or motorcycle touring, water can be relentless. A dry bag backpack like the Big River Dry Backpack uses a strong 420D nylon fabric that resists abrasion and keeps contents dry even when splashed or submerged briefly. Packing cubes like the Hydraulic Packing Cube use a TPU laminated 70D ripstop Nylon that is water-resistant but not fully waterproof—they handle light rain and damp conditions but won't survive a dunking.

Durability and Weight Trade-Offs

Durability often comes at the cost of weight and packability. Dry bags use thicker, more rugged materials to withstand rough handling and sharp objects. The Big River Dry Backpack's 420D nylon is heavier and bulkier than a packing cube's 70D ripstop, but it offers superior protection for demanding activities.

Packing cubes are lighter and more compressible, making them ideal for travel where every ounce matters. The Hydraulic Packing Cube's welded construction adds strength without adding much bulk, and its translucent window lets you see contents without opening—a convenience you won't get with most dry bags.

When to Use Both

You don't have to choose one exclusively. Many campers use packing cubes inside a dry bag backpack to combine organization with waterproofing. The cubes keep clothes and gear sorted, while the dry bag provides the primary water barrier.

This combination works especially well for multi-day hikes where you need both quick access to items and reliable protection from rain or river crossings. Packing cubes also help you compress gear, making it easier to fit everything into a dry bag backpack.

Trade-Offs at a Glance

• Water Protection: Dry bags like the Big River Dry Backpack are fully waterproof; packing cubes like the Hydraulic Packing Cube are only water-resistant. For river crossings or heavy rain, always choose a dry bag.
• Organization: Packing cubes excel at separating and finding items quickly; dry bags usually offer one large compartment. Use packing cubes inside a dry bag for the best of both.
• Weight and Packability: Packing cubes are lighter and more compressible; dry bags are heavier but more durable. For ultralight trips, packing cubes save space and weight.

Product Facts

• Hydraulic Packing Cube: The Hydraulic Packing Cube is water-resistant and uses a TPU laminated 70D ripstop Nylon with a fully welded construction. This keeps dust and light moisture out while staying lightweight, but it is not fully waterproof, so avoid submerging it.

  

• Big River Dry Backpack: The Big River Dry Backpack uses a strong 420D nylon fabric that is durable and abrasion resistant. This rugged material is built for wet and rough conditions like kayaking or rafting, offering reliable waterproof protection.

  

Which Should You Choose?

Best for

• Paddlers and adventure travelers who need reliable waterproofing for electronics, clothing, and sleeping gear.
• Campers who want to keep gear organized inside a larger backpack or duffel.

Not for

• Scenarios requiring full submersion protection—choose a dry bag instead.
• Travelers who prioritize lightweight packing and quick access over maximum water resistance.
