Dry Bag Q&A: Waterproof Gear for Outdoor Adventures

 Are dry bags really waterproof?

Yes—if sealed properly. Most waterproof dry bags use roll-top closures and durable materials like PVC or TPU fabric. Not all are submersible, so check the IP rating:

  • IPX6 dry bags: Splashproof and brief submersion
  • IPX7 dry bags: Submersion up to 1m
  • IPX8 dry bags: Submersion beyond 1m

 How do I seal a dry bag correctly?

To maintain a watertight seal:

  • Pack your gear with space at the top
  • Roll the top down 3+ times
  • Clip the buckle securely
  • For extra floatable dry bags, trap a bit of air inside

 What can I use a dry bag for?

  • Paddleboarding dry bags
  • Kayaking and canoeing essentials
  • Wild swimming kit
  • Rainy hikes or muddy festivals
  • Beach gear (sand-proof & splash-proof)
  • Separating wet gear from clean clothes while travelling

 Can I use it for dirty laundry or smelly kit?

Absolutely. Odour-proof dry bags make excellent stuff sacks. Keep your clean gear fresh and hide your stinkiest socks with confidence.

 Do dry bags float?

Yes—when air’s inside. These floating dry bags aren’t life-saving devices, but they’ll bob along beside your SUP or kayak like trusty little cargo pods.

 What are dry bags made of?

  • PVC tarpaulin: Tough, rugged, perfect for rocky terrain
  • PU-coated nylon dry bags: Lightweight and great for layering inside other backpacks

 What is a wet bag for Swimming?

A wet bag is a waterproof or water-resistant pouch designed to store damp swimwear, towels, and gear after swimming. Made from materials like polyester laminated with polyurethane or neoprene, it prevents water from leaking onto other items in your bag. Wet bags are essential for swimmers, gym-goers, and beach visitors to keep dry belongings safe from moisture.

 How does a Wet Bag differ from a Dry Bag?

  • Wet bags are designed to contain moisture inside, ideal for storing wet swimsuits.
  • Dry bags are fully waterproof and meant to keep water out, protecting dry items (e.g., clothes, phones) from getting wet. However, they can also hold wet gear. Dry bags are often larger and more durable, suitable for wetsuits or beach trips.

💦 Waterproof Bags vs Dry Bags — What’s the Difference?

What Is a Waterproof Bag?

A waterproof bag is designed to resist water entry using materials like PVC or TPU. It may include zip-seal, flap, or roll-top closures.

Waterproof bags come in various forms. Backpacks, duffels, and totes and offer protection from rain, splashes, and the odd spill.

What Is a Dry Bag?

A dry bag is specifically built to be airtight, watertight, and highly durable. It typically features a roll-top closure system, which, when appropriately sealed, traps air, allowing it to float and keep your contents completely dry.

These are essential for:

  • Paddleboarding or kayaking
  • Wild swimming or boating
  • Camping in unpredictable weather
  • Keeping spare clothes and gear dry on the go

 How do I clean and care for a waterproof dry bag?

  • Rinse with fresh water after saltwater sessions
  • Air dry fully before storing
  • Avoid abrasive cleaners to protect the waterproof coating

 How can I test if my dry bag is leak-proof?

Try the tissue test:

  1. Place dry tissue inside
  2. Seal and briefly submerge
  3. Dry outside, then inspect—dry tissue = success

 How long do dry bags last?

Years, when cared for. Heavy-duty models survive beaches, boats, and backpack abuse. Lighter ones may lose waterproofing over time (but can be re-treated)

Delighted with my Salty Kit 30L backpack. Roomy enough for my work and gym stuff to fit in one compartment. It has kept everything dry as bones throughout a wet British winter.

Fantastic bag, great alternative to the musto waterproof 30L bag that is no longer available. The colour is great, along with the small pocket on the inside and outside (which the musto bag didn't have!) I love that the handles are detachable, a clever feature since handles tend to wear out first. I'm really pleased with my purchase. Thank you Salty Kits.

Brilliant bag

We took it on a trip to the USA and got many complements on the bag and people asking where we got it from. We have passed on your details and hopefully you may get some orders from the USA!

Top quality, nice bag although a good alternative would be to have a clip fastening. Slightly bigger would also make it easier to get the phone out.

Great product. Was worried I’d ordered too large. But product fits in as cabin bag and is super comfy. I wore it all day when it was full and had no issues. And of course it’s waterproof.
Actually now my favourite bag!
