No matter if you are kayaking in a remote canyon, walking along a wooded trail, or riding a motorcycle during a rainy day, a dry bag is something that you must consider getting. A dry bag is an essential piece of gear that protects your valuables from water, dirt, sand, and dust. Now that you know what a dry bag can do for you, how do you know which one to get since there are so many options in today’s market?
In the guide below, we will explain everything you need to know about the materials and designs of a truly waterproof dry bag to help you get the most suitable size for your outdoor adventures.
What Makes a Dry Bag Truly Waterproof?
Not all “waterproof” claims are created equal. To ensure your dry bag will perform in wet or extreme environments, pay attention to these key features:
1. Material Quality
-
500D PVC Tarpaulin: This material is well known for its durability and can withstand various kinds of force, making it one of the best options for creating a dry bag. It is thick and durable, providing superior protection against water.
-
TPU (poliuretano termoplastico): TPU is generally regarded as a more advanced and greener option due to its light weight, flexibility, and resistance to cold. However, it often comes at a pricier rate.
2. Sealing Technology
-
High-Frequency Welded Seams: This manufacturing technique seals the bag’s seams with an ultrasonic stitchless method, creating watertight seals.
-
No-Stitch Construction: Completely circumvents the use of stitches, and hence needle holes, minimizing possible leak areas.
3. Closure System
-
Roll-Top Closure: Considered the gold standard in waterproofing. A roll-top must be folded and clipped at least three times to ensure maximum waterproof seal.
-
Zipper Seals: While convenient, zippers must be specially designed for waterproofing (like TIZIP or YKK AquaSeal), and they usually require more maintenance to retain their seal integrity.
Key Criteria for Choosing the Best Waterproof Dry Bag
1. Capacity: Pick the Right Size
The best size depends on your activity. Here’s a quick reference table to guide your choice:
| Capacity (L) | Recommended Activity | Items It Can Hold |
|---|---|---|
| 5–10L | Daily biking, SUP | Phone, wallet, keys, 1 T-shirt |
| 15–20L | Half-day hike or kayaking | Extra clothing, small first-aid kit, water bottle |
| 30–40L | Multi-day camping, sea fishing | Sleeping bag, camp gear, light jacket |
| 50L+ | Long travel, gear hauling | Full set of clothes, thick jackets, multi-day supplies |
2. Activity-Specific Recommendations
-
Kayaking / Paddleboarding (SUP): Search for 10-20L bags that are compact with a secure roll top and made from buoyant materials.
-
Multi-Day Hiking: A 30 to 40L dry bag with straps and padded support helps distribute weight over long distances.
-
Beach Camping: Ideal bags have side pockets for quick access, so pick a larger than 30L, sand-resistant, and durable dry bag.
-
Motorcycle Commuting: Go with a sleek trimmed 20–30L weather-tight bag with strong attachment points and reflective elements for safety.
Comfort and Convenience Matter
A good dry bag keeps your belongings dry, but it should also be easy and comfortable to carry.
-
Shoulder Straps: Adjustable single or double straps allow your dry bag to be transformed into a backpack for hands-free transport.
-
Grab Handles: Reinforced top handles make it easy to carry or pull from a boat’s hatch or motorcycle’s rack.
-
Non-Slip Coating: Used primarily in water sports, this bonus feature adds grip when wet.
Bonus Features to Look For
-
External Zipper Pockets: For items designed to be accessed frequently (splash-proof required).
-
Transparent Touchscreen Window: This lets you safely use your phone on the go while keeping it protected.
-
Floatation: Air-trapping designs or foam inserts keep your bag from sinking—critical for water sports.
-
Strisce riflettenti: Increases visibility in low-light conditions for added safety.
