Complete Guide to Scuba Diving Gear Bags: Types, Features, and Selection

By Ray Hollister March 5, 2026

After four decades of hauling scuba equipment across boat decks, through airports, and over marina parking lots, veteran diver Ray Hollister has seen more dive trips ruined by bad gear bags than actual equipment failures. This episode breaks down everything you need to know about choosing the right bag for your diving adventures. Whether you're a new diver wondering why your gear smells like a swamp or an experienced traveler tired of zipper blowouts, you'll learn exactly what separates functional dive bags from expensive disappointments.

Key Takeaways

  • Drainage is the one feature you absolutely cannot skip. A bag that traps water inside turns into a mildew factory, like leaving wet towels in a sealed plastic bin during summer. Look for bags that drain from multiple angles, not just the bottom, since your bag won't always sit upright during transport.
  • Material choice depends on how you dive. Heavy-duty nylon lasts for decades and resists scrapes, while PVC-coated bags are easier to clean and great for boat diving where splashing is constant. Mesh bags drain beautifully but offer almost no protection for expensive equipment like dive computers.
  • Roller bags sound convenient but often fail in real diving conditions. Sand, gravel, and cracked boat ramps make wheels useless, so most divers end up carrying them anyway while dealing with the extra weight and parts that can break.
  • A full recreational dive setup needs 80 to 120 liters of space. That's roughly three to four times bigger than a standard carry-on suitcase, which explains why divers checking bags at airports is so common.
  • Simple compartment layouts beat complicated pocket systems. One large main space with a few accessory pockets gives you flexibility, while bags with too many dedicated compartments force you to fight against a design that never quite fits your actual gear.
