10 Best Waterproof Backpacks for Wet Adventures in 2021

Water. It comprises 90% of our body weight, is the giver of life, washes our bodies, baptises our babies and nourishes the very plant life we put on our plates. In certain circumstances, however, it’s also a mighty pain in the posterior. Ever spent a long trek eagerly awaiting that moment when you could whip out your fresh socks only to find them sodden by intrusive rainstuff? We feel your pain, dear CooloftheWilder! That pain, however, is largely avoidable. H20 is remarkable stuff. It has ways of evading the protection of even the best backpack rain covers and sometimes even manages to permeate the ‘impermeable’ waterproof materials so boastfully highlighted by our backpacks’ producers.

We at Cool of the Wild, however, got a bit tired of soaked socks, soggy sandwiches and nights spent in involuntarily waterbed-like sleeping bags. We said ‘no’ to H20 and a big almighty ‘yes’ to finding the best waterproof backpack for all your outdoor adventures. Here’s a sneaky peek at our top 10 choices, but for more information on each you can skip down to a summary of each backpack.

The 10 best waterproof backpacks for all your outdoor adventures

GOT BAG 4 Ocean Rucksack

Eco-conscious: Made from recycled ocean plastics and coated with bio PU

Eco-friendly waterproof backpacks are not easy to come by. In fact, we were seriously struggling to find any at all until we stumbled upon the GOT BAG 4 Ocean Rucksack. Each 23 litre bag is made from 3.5kg of plastic that is recovered from our oceans. Plus, to ensure maximum waterproofness, the fabric has a Bio-PU coating that is kinder to the environment than PFC-based treatments. It’s not the kind of waterproof backpack that you’d go swimming with, but it is 100% waterproof keeping your stuff dry in stormy and wet conditions. Its simple design features a flexible roll top, an external zippered pocket and side compression straps. Additionally, it houses a removable 15” laptop case making it an ideal commuter backpack and bridging the gap between wet weather adventures and everyday life superbly.

Sea To Summit Hydraulic Dry Pack

Eco-conscious: PVC-free

On our hunt for the supremely waterproof pack we came across something which is not only that but just might be bombproof too! The awesome S2S Hydraulic Dry Pack is a highly versatile, tough, durable, comfortable and superbly functional beast of a pack that will keep your gear and goodies dry even in the event of a biblical flood. At 35l, you might not be able to squeeze in as many animals as old Noah did his ark, but the hydro comes in 65, 90 and 120l sizes too, so you can at least take a few of your furry friends along with you. And they’ll be dry. Very dry.

The S2S Hydraulic Dry Pack is made of tough 600D laminated fabric and features a welded construction to avoid water sneaking in through any seams. The padding on the shoulders and back is ample and the waist belt removable, meaning wherever you go, you’ll go in comfort (even with two penguins in there).

SealLine Black Canyon Boundary Pack

Eco-conscious: PVC-free

Reasonably lightweight, durable and not quite as pricey as the S2S Hydraulic Dry bag, the Black Canyon offers stiff competition to its rivals in the fully dunkable dry bag category. It also comes with one winningly standout feature in particular – it’s bloody huge! At 115 litres, the capacity of the SL Black Canyon is the largest in our review and enough to throw in a few water-fearing family members should you wish. What’s more, this frankly enormous sack is entirely PVC-free, so it provides an environmentally-friendlier option for the eco conscious adventurer. While comparable to the Acquapac, S2S Hydraulic and Umpqua Tongass (below) in terms of comfort and waterproofing, if space is what you’re looking for, this is your guy/gal!

Aquapac 28L Toccoa Wet and Drybag

The Aquapac Toccoa is an all round excellent and versatile waterproof backpack that is as at home on the river or under a waterfall as it is trekking through heavy rainfall. It has more padding and greater capacity than the Ortlieb Velocity, and more waterproofness that the S2S Flow. It also competes fiercely with the Overboard ProVis in almost all areas other than the lack of internal pockets where the ProVis has the upper hand. The Toccoa makes up for this with two highly useful side mesh pockets and daisy chain loops to clip gear onto the outside of the pack. Additionally, the roll top seals either at the top or the sides of the bag which further adds to its versatility. This is a super comfortable, durable and fully submersible day pack that is highly stable when carried in higher energy situations.

Ortlieb Velocity 20L Backpack

For a versatile, light-load day-pack with excellent waterproofing capabilities, the Ortlieb Velocity offers a tidy, well-made alternative to its bigger brethren. At 20l, this little pack is lacking in the capacity stakes and the multiple rolls required to fasten the velcro top closure can shave off a further few inches of storage. That said, the Velocity makes up for its diminutive proportions and relatively large price tag with very durable materials, a detachable waist belt and a useful inner pocket for keeping smaller bits and bobs separate. A decent option for the minimalist-minded, but all-in-all comes up just short of small pack competitor the Aquapac Toccoa in almost all specs and features (including size!).

Sea To Summit Flow 35L Drypack

Eco-conscious: PVC-free

For hikers or multi-sport adventurers seeking something that is hugely versatile, the S2S Flow just might be the pack you’re looking for. Boasting the comfort, compartmentalised storage and overall functionality of a standard hiking pack and the waterproofing capacity of a canoeing pack, this is a true all-rounder that is at home in any environment. While not as sea or lake-worthy as its S2S cousin the Hydraulic Dry Bag, the S2S Flow has you covered for just about everything else you could get up to, barring a complete dunking. Far superior in terms of versatility and comfort to all other items in our review and offers a bit more storage space than the similarly versatile Aquapac Toccoa. Pity about the price tag…

BackSak Waterproof Backpack (35L)

With tough, welded seams, durable 500D PVC material and decent capacity, the Backsak 35L offers a very reliable and nicely priced alternative to its pricier competitors. While it may not offer complete dunkability, it will easily handle a downpour and is ideal for rainy trekking or cycling adventures. Features-wise, it boasts handy interior and exterior pockets for smaller items you don’t want to get mixed up with the rest of your gear, and a side-closure option to maximize storage. Bargain!

Big Horn Products 30L Waterproof Backpack

Durable, reasonably lightweight and pleasingly inexpensive, the Big Horn 30L is another decent all-rounder for those on a budget. The exterior webbing and draw-cords are handy features for drying wet gear on-the-go and side mesh pockets ideal for stowing water bottles. Compared to other budget competitors the Sarki and Backpak, the Big Horn offers a little less comfort-wise but is marginally more streamlined for canyoning or canyoneering pursuits.

OverBoard Waterproof Pro-Vis Backpack(20l)

While the OverBoard Pro-Vis is a touch on the skimpy side capacity-wise, it does a lot of things rather well. It’s very well-made, featuring a welded construction, high-vis and durable PVC, compression straps, reinforced side and bottom panels, good padding and a few handy pockets inside and out for organizing your gear. It offers less storage than the other budget options in our list and is similar in terms of waterproofing, but has the advantage of ergonomic, padded straps. These offer plenty of cushioning and a ventilated back panel as good as any you’ll find on a mid-range, out-and-out hiking pack. Compared to other low-capacity packs such as the Ortlieb velocity, the Overboard offers a more comfortable carry. For a bit more space and superior waterproofing, the Aquapac Toccoa is a better bet.

Umpqua Tongass 1800 Waterproof Backpack

Eco-conscious: PVC-free

Boasting complete dunkability, durable 420D welded nylon material, superior compartmentalisation to its competitors and a host of handy features, the UT 1800 is a love-it-at-first sight kinda pack. There’s a catch though, one that hangs by a little thread at the bottom of the sack and begins with a $ sign. Yep, all that goodness comes at a cost… For your extra $, however, the UT 1800 goes a lot further than most of its competitors. With an internal hanging pocket (which can be clipped on inside or out), a secondary roll-top compartment, waist belt pockets, fishing rod carriers, storage space between the two compartments, water bottle pockets and web tool attachment points on the shoulder straps, the features on this are rivalled only by the S2S Flow in terms of convenience, practicality and storage options. Compared to other high-end packs the SealLine Black Canyon and S2S Hydraulic Pack, the UT 1800 provides similar waterproofing and less in terms of storage, but a lot more in way of comfort, useful features and versatility.

What makes a great waterproof backpack?

Waterproofness

This no-brainer merits inclusion merely because there are, it seems, varying levels of how waterproof a pack can be. While some packs are able to withstand complete submersion on a kayaking, canyoning or canoeing trip, others are only waterproof as regards the stuff that falls from the sky – and in varying quantities at that. Knowing what level of waterproofing you need will simplify the selection process and help make sure you aren’t spending too much or otherwise getting something unsuitable for your outdoor adventures’ wetness levels. For canyoning, for example, you’ll probably need something 100% waterproof. For canoeing or kayaking, the same is true only if you happen to do a lot of rolls or are prone to involuntary capsizing. For hiking, cycling and other sports on dryish land, on the other hand, you can probably get away with something not fully submersion-proof.*

*Unless you live in the Pacific Northwest. Or Scotland.

Comfort

As with any backpack, waterproof or not, you want yours to be comfortable on your back. Essential to comfort are the padding on the pack’s strap and back, the load distribution (how evenly the weight is shared across your shoulders, back and waist), and other features such as ventilation panels and a chest strap.

Weight and size

The less your bag weighs, the more gear you can potentially carry or the lighter the load on your back…always a bonus! Be sure to check your pack doesn’t lose too much in the way of capacity if it features a roll-top closure system. Some packs offer both this and an alternative closing option such as side clips, meaning you can vary the capacity to suit your load.

Best use/versatility and functionality

Certain packs excel in or are custom made for certain activities. While a kayaking pack might serve you relatively well on a wet hiking trip, it will likely lack many of the features you’d look for in an out-and-out trail pack such as multiple compartments, added comfort from padding, better load distribution, hydration bladder compatibility and lightweight materials.
Conversely, a decent waterproof hiking or cycling pack might just not be waterproof enough for seaborne adventures, m’hearties, so going for something of the PVC, moulded material, seamless, submersion-proof variety will serve you better!

Features of the best waterproof backpacks

• Mesh pockets

  For storing wet gear, water bottles, and flip flops, mesh pockets are a common feature on waterproof backpacks.

• Zippered pockets

  These are handy for accessing small gear without opening the main compartment. Internal zippered pockets are also useful for organising your gear.

• Roll-tops

  Roll-top backpacks offer greater water protection for your kit as well as versatility. Most roll-top backpacks are secured with buckles on either the side of the pack or together at the top which creates a large carry handle or extra attachment point.

• Gear loops

  Access bits and pieces, such as a waterproof first aid kit or a waterproof camera, without getting the rest of your kit wet. The best waterproof backpacks are made with gear loops. These can also double as attachment points for securing the backpack.

• D-rings

  Sturdy D-rings let you attach a carabiner clip and secure the backpack to a paddleboard, kayak, or canoe.

• Shoulder Straps

  Straps on waterproof backpacks should be made from quick-drying fabrics. Some have a webbed design which allows them to shed water and dry even faster. The straps on waterproof backpacks are typically less padded than the straps on regular backpacks.

• Waist and chest straps

  Most dry bags are fitted with a simple waist strap that keeps the bag from bouncing. Larger packs should have a more comfortable waist strap as well as a chest strap.

• Compression straps

  These are usually found on the sides of the pack. They clinch down the roll-top but, to minimise gear movement, some have additional horizontal compression straps.

• High-visibility strips

  Another useful feature if you like to get out before sunrise or after sunset. The more are high-visibility strips the backpack has, the more visible you’ll be to passing cars or other adventurers.

• Haul handle

  A really useful feature for moving your bags from place to place. They’re also handy for pulling bags out of storage holes or out of other bags.

• Bungee attachments

  Bungee cords on the back of the backpack give you quick access to larger items, like your helmet or wet suit shoes.

Different uses of waterproof backpacks

Although waterproof backpacks are suitable for any outdoor activity where you’re likely to get wet, some have specific features that make them better for certain activities.

Below we’ve listed the most important features to look for in a waterproof backpack according to its use:

Kayaking and canoeing

• Roll top
• D-ring
• Compression straps (if you have a kayak with small storage hatches)
• Mesh pockets – for water bottles and storing wet gear
• Shoulder, waist, and chest straps are less important as you probably won’t need to carry the
  backpack very far.

Paddle boarding

• Waterproof rating – should keep your kit dry if submerged
• D-rings – for attaching the backpack to your paddleboard
• Gear loops – for securing a mask and snorkel or waterproof camera
• Mesh pockets – for water bottles, reef-safe sunscreen, or wet gear

Hiking

• Larger storage capacity – 25 litres or above
• Comfortable shoulder strap – should be more padded than other types of waterproof backpacks
• Waist and chest straps – for spreading the weight of the pack
• Zippered pocket on the waist strap (useful but not essential)
• Mesh side pockets for water bottles
• Bungee cords – for a top layer or rain poncho
• Gear loops

Cycling

• Light loop attachment
• High-visibility strips – especially if you will use the backpack for road cycling or commuting
• Bungee cords or a big mesh pocket – for storing your helmet

Canyoning

• Waterproof rating – should be able to manage short submerges
• Extra durable fabric – whilst canyoning it’s very likely to get scratched and scraped on rocks
• Roll top
• Compression straps – to keep your gear from moving inside the pack and making it more compact, this is useful in canyons with very narrow sections
• Zippered pockets
• A large mesh pocket of bungee cords – for taking your wet clothes home

Skiing and snowboarding

• Comfortable shoulder straps
• Waist strap
• Bungee cords – for your helmet and ski goggles
• High-visibility strips

Keeping your gear (or penguins and family members) dry while out in the elements is a big deal and a tricky business. Whatever you plan on getting up to and whatever your budget, however, we’re sure in the above list of waterproof wonders you’ll find something suitable for your upcoming adventures!

Happy (and dry) adventuring!
