Looking for the best dry bag to keep your kit safe and dry? Read on. Travel isn't about 'finding yourself', it's about getting sand, dirt and water in your precious stuff and learning to live with that, right? Even checking-in a case at an airport risks it being left in a puddle/out in the rain while it waits its turn to be loaded in the cargo hold.

It doesn't have to be that way. Whether you're planning to spend time on the beach, on boats, surfing, fishing, cycling, kayaking or canoeing, trekking, camping, or anything else near rivers, oceans, beaches or deserts, there's only one way to protect your gear: a dry bag. 

Enter: the best dry bags for the outdoors. These picks will protect your belongings, keeping everything from your clothes to your action camera to your sleeping bag safe, whether you're facing water, sand, dust, humidity, or just a sloppy baggage handler. 

There are three things to think about when deciding which of the best dry bags to buy: size, material, and closure type. Size-wise, choose a high capacity backpack if you plan to go trekking or kayaking, though much smaller if you're cycling or just planning a jaunt to the beach/resort pool. For materials, you'll see a lot of vinyl, though sturdy nylon materials are now appearing that have a much soft, less industrial (and less shiny) look, while remaining waterproof. 

However, what most of the best dry bags have in common is a roll-top closure. Although you will also see sealed zippers, roll-tops that must be rolled three or four times before being sealed using clips is a common and highly effective way to keep out water. 

For those on a mission, our current top pick for the best dry bag is the SealLine Boundary Dry Pack, chosen for its huge capacity, certified waterproofing, and its ability to perform as an all-round travel bag for outdoor use. However, if you're after something cheaper, smaller, or with pockets, we've got options for you too. Check out our guide to the best dry bags of the year.

Cue the great value Overboard Dry Flat Bag, a handy – and hard to miss – ripstop nylon fabric bag that's as super-light as it is versatile.

Closure: Roll top
Volume: 10L, 20L, 30L
Reasons to buy
+Comfy backpack style straps+Easy-access roll top design
Reasons to avoid
-Side handle isn't robust enough-Overpacking weakens stitching

While it might not have the adjustability or balancing chest harness of the Sea to Summit Hydraulic Day Pack, the Aqua Quest Mariner is an admirable option if you're after something more akin to a waterproof backpack. For those days when the 35-litre capacity of our previous pick might be overkill, Aqua Quest's 10 and 20-litre options may be more fitting. There’s a duffel-like side handle to this dry bag as well as backpack-style shoulder straps. Their more portable size, as well as the versatile carry options, are just two reasons why the Mariner Lightweight should be on your radar.

The most stylish dry bag for urban travel

Material: Waterproof ripstop Bergshell 400D 100% polyamide
Closure: Roll-top
Volume: 23L
Reasons to buy
+Padded pocket to protect a 15-inch laptop+Compression straps to squash-down+Loop for a bike light
Reasons to avoid
-Not for serious adventures

Here's something from Swedish brand Fjӓllrӓven for urban types who sometimes have to brave the outdoors – and specifically the rain – with tech in tow. A smart-looking daypack complete with a padded area for a 15-inch laptop, a zipped pocket and even pen holders inside, the Ulvo Rolltop 23's most obvious trick is its roll-top closure to keep out downpours. However, although we love its two outside pockets for storing a water bottle and/or umbrella, secret zipped pocket, and loop on the front for a bike light, the Ulvo Rolltop 23 is all about its waterproof, yet soft and smooth (and part-recycled) Bergshell fabric. At 23 litres the Ulvo Rolltop 23 isn't going to take much gear, but for anyone on an urban commute, a light hike or a cycle ride through bad weather it's one of the best-looking options we've seen.
