The Osprey Transporter Waterproof 70L ($360) is a rugged, fully waterproof duffel bag made for waterlogged trips. Sure, you could take it on an urban vacation or pack it for a long-haul flight, but that’s not its intended purpose—or a smart use of the money you’ll be paying for it. Its backpack straps are the comfiest of the waterproof bags we’ve tested, but with stiff zippers and otherwise limited carry options, this isn’t the easiest bag to use.

Osprey Transporter Waterproof 70
For this season's top models, see our guide to the Best Duffel Bags.
Like most waterproof duffels, the Osprey Transporter 70 leans minimalist. There’s a single internal mesh pocket that detaches via hook-and-loop tabs and is designed to sit on top of your packed gear. I found the setup clunky—the pocket gets in the way while you pack and doesn’t offer much utility. I would’ve preferred a compartment sewn into the wall of the bag, like on the Panga. Thankfully, this bag does have two internal compression straps, which help relieve tension from the main zipper, and external daisy chains and lash points for securing the bag to a raft or a roof rack. River rats probably won’t mind the sparseness given the protection the Transporter offers, but it falls short for anyone hoping for more refined organization.
Packing was a mixed experience overall. The main Transporter’s compartment opens via a watertight YKK AquaSeal zipper that runs straight across the top. The zipper is beefy and secure—but also tough to open and close. And because it doesn’t span end to end, reaching into the bag’s corners is tricky. (Still, it’s a bit easier than the Panga, whose even narrower opening can be maddening.) Compared to lid-style duffels like the Patagonia Black Hole or the REI Co-op Big Haul, though, the Osprey Transporter Waterproof is more restrictive.
The build quality on this bag is decent, but not top-notch. Osprey uses a 630-denier ripstop nylon material that has a double TPU coating, which felt reassuringly tough throughout testing. I dragged the Osprey Transporter through the airport, tossed it in and out of cars, and brought it on a multiday camping trip in the mountains. After all that, the bag looked practically new.
It’s not as absurdly burly as the Panga, which is built with Yeti’s iron-tough ThickSkin material (high-density nylon, also with a TPU coating, and a molded base). And the Transporter’s material isn’t as thick as non-waterproof bags like The North Face’s Base Camp model (1,000D) or the Black Hole (900D). However, while the Expedition’s 840-denier fabric is thicker than the Transporter’s shell, I found the Transporter’s build superior overall.
This bag’s compression straps, zipper, and fabric all inspire confidence, and I’d trust this duffel to handle repeated abuse in riverine or alpine conditions. The base is made from the same material as the rest of the shell—not reinforced separately—but that’s a minor omission given the quality of the rest of the build.
This is where the Osprey Transporter Waterproof Duffel 70 shines. With an IPX7 rating, it’s completely waterproof and fully submersible in up to three feet of water for 30 minutes. I dunked it repeatedly in June Lake just to test that claim, and everything inside stayed completely dry. (Just to prove that I took it to a variety of places, a brief New York drizzle didn’t faze it, either.)
Its YKK AquaSeal zipper, non-corroding metal hardware, and TPU-coated shell all contribute to the Transporter’s fortresslike appeal. I have no reservations about using this bag in wet or snowy conditions—it will shine on any boat-based adventures you can conceive of—and it easily outperforms standard water-resistant duffel bags like the REI Roadtripper or the Hole in this regard. It’s on par with the Yeti Panga and a slight step up from the Expedition, whose zipper feels a bit less confidence-inspiring.
When you consider that the Transporter Waterproof Duffel is mainly designed for water protection, not comfort, its backpack carry is surprisingly solid. The bag hugged my back well, and the shoulder straps—while not the most padded compared to all the duffels I tested—got the job done without any major rubbing or hotspots. I hauled about 30 pounds of gear through LAX and JFK and later from a campsite in the Sierra down to June Lake without much discomfort. Overall, the Transporter’s backpack mode feels better than the other waterproof, backpack-capable bag we tested, the Yeti Panga. My only gripe was the slightly wide strap spacing, which occasionally pressed awkwardly into the sides of my chest.
This duffel’s real weak point is its topside carry system—or lack thereof. There’s no dedicated handle on the Transporter; instead, Osprey added a hook-and-loop wrap to cinch the backpack straps together. It works in a pinch, but the grip bent under the bag’s weight and wasn’t pleasant to hold for more than a few minutes. Plus, the Transporter’s TPU-coated fabric is plasticky and tugged at my leg whenever it brushed against me, making me want to hold the bag further out just to avoid skin irritation. For short lifts, the Transporter is fine. For long walks, stick to backpack mode. (It’s also worth noting that another waterproof model, the NRS Expedition DriDuffel, has a great grab handle but no backpack straps.)
At 2 pounds, 7.6 ounces, the Transporter is reasonably light for a waterproof duffel, especially when compared to the Panga, which weighs over 5 pounds. The weight feels justified given the protection and durability you get in return. It’s not ultralight, but it’s well-balanced for its intended use.
It doesn’t come with a stuff sack, but the flexible material allows it to roll or fold down into a relatively compact shape—enough to stash in a closet or suitcase when needed. (That said, I wouldn’t leave it stuffed for long-term storage.) The backpack straps are technically removable, but they’re a pain to detach and reattach. Re-clipping them after a lake test took several minutes and more fumbling than I expected. It’s a minor gripe, but one that makes me appreciate duffel bags with easier clip-on systems, like the Big Haul or the Expedition.

Longevity
Choosing durable outdoor gear and keeping it in use for longer is one of the best ways to reduce environmental impact. Our proprietary longevity rating assesses factors like overall build quality, materials, fabric denier, component durability, and real-world performance. A green check indicates that we expect the product to be long-lasting relative to its peers, a yellow check mark indicates average longevity, and a red X indicates a product that may have a limited lifespan.
Recycled Materials
Recycled materials are prevalent in outdoor gear, with nylon, polyester, wool, and down among the most common, but the composition varies widely. A green check mark indicates the product is made with a substantial amount of recycled materials (100% recycled or the core fabric that makes up most of the product is recycled), a yellow check means it contains a moderate to small amount of recycled materials, while a red X means there are no recycled materials in the product.
Bluesign Approved
Bluesign Technologies, based in Switzerland, operates a third-party textile management system that ensures materials are manufactured to strict environmental, chemical, and worker safety standards. A green check mark indicates a product is either a Bluesign Product (contains at least 90% Bluesign-approved fabrics and 20-30% Bluesign-approved accessories) or features a significant amount of Bluesign-approved materials. A yellow check mark means it uses some Bluesign-approved materials but less than the aforementioned category, and a red X means there are no Bluesign-approved materials in the product.
PFAS-Free Materials
This product's waterproofing is made without per- and polyfluoroalkyl substances (PFAS). These synthetic compounds are known as "forever chemicals” because they take an extremely long time to degrade, if at all. PFAS can eventually end up in everything from soil to drinking water and have been linked to a range of health issues.
Responsible Manufacturing
This criterion evaluates a brand’s commitment to fair wages, safe working conditions, and reducing environmental impact through certifications and programs like Fair Trade Certified, Fair Wear Foundation, Worldwide Responsible Accredited Production (WRAP), and the Fair Labor Association, while also recognizing brands that manufacture primarily in the U.S. or Europe under strict labor and environmental regulations. A green check mark indicates a brand meets our responsible manufacturing criteria, while a red X means it does not.
Recycled and/or Reduced Packaging
Packaging can add significant waste to outdoor gear purchases, so many brands work to reduce its impact by using recycled materials, incorporating Forest Stewardship Council-certified paper products, and minimizing plastic and paper use. A green check mark indicates a brand uses recycled or reduced materials across all of its packaging, a yellow check indicates moderate or limited use of recycled or reduced packaging, and a red X indicates the brand does not make either of these efforts.
Repair Services
Repair services extend the lifespan of outdoor gear and reduce overall consumption, though programs vary widely. Some brands offer comprehensive repairs for a range of issues, while others provide limited or no repair support. A green check mark indicates a robust repair program, a yellow check mark indicates limited repair services, and a red X indicates the brand does not offer repair services.
Resale and/or Recycling Services
Resale and recycling programs help keep outdoor gear in circulation longer and out of landfills, ranging from trade-in resale platforms that offer store credit to take-back initiatives that recycle products at the end of their usable life. A green check mark indicates a brand offers both resale and recycling programs, a yellow check mark indicates it offers one or the two, and a red X indicates it offers neither.
Carbon Footprint Tracking
This criterion evaluates whether a brand measures, reports, and works to reduce its greenhouse gas emissions using established frameworks such as the Higg Index, Greenhouse Gas Protocol, or The Change Climate Project. A green check mark indicates a brand publicly reports greenhouse gas emissions data, sets clearly defined reduction targets, and uses established tracking frameworks such as Higg or The Change Climate Project. A yellow check mark indicates the brand tracks emissions and outlines reduction goals but provides limited data, lacks science-based verification, or does not clearly report progress. A red X indicates the brand does not appear to track greenhouse gas emissions or provides so little information that its efforts cannot be verified.
Annual Impact Report
Annual impact reports provide transparency and accountability by outlining a brand’s sustainability efforts across areas such as material sourcing, greenhouse gas emissions, waste, water use, supply chains, and packaging. A green check mark indicates a brand publishes a detailed, brand-specific impact report that closely aligns with our sustainability criteria and leaves little room for ambiguity. A yellow check indicates a brand provides some relevant sustainability reporting but lacks detail in key areas or is covered only briefly within a parent company report. A red X indicates a brand does not regularly publish an impact report.
Yeti Panga 75L Waterproof Duffel ($350): A Burlier Option
The Panga and Transporter both carry an IPX7 rating, so they’ll keep your gear dry even if it takes an unplanned swim. But in terms of overall construction, the Panga’s high-density nylon shell and EVA-molded bottom give it a thicker, burlier feel, and we prefer its sewn-in sidepanel mesh pockets over the Transporter’s single free-floating one. That said, the Panga’s stiffer build makes it harder to stuff gear into the corners and ends. And while the Transporter at least attempts to make hand-carrying a little easier with a padded grip, the Panga skips handles entirely. In backpack mode, the Panga’s haul handles dug into our tester’s neck and back, while the Transporter’s stayed out of the way. If your trips involve long portages, the Transporter’s superior carry comfort is worth the extra $10. Otherwise, this is a bit of a toss-up. For more, read our review of the Panga Waterproof Duffel.
NRS Expedition DriDuffel 70 L Dry Bag ($350): Better in Hand, Less so on the Back
If you can’t live without a proper hand-carrying handle, you’re in luck with the Expedition DriDuffel. Its grip is thick and resists bending, making it one of the most comfortable our tester has used. This bag also comes with a single padded shoulder strap instead of backpack straps, which works fine for shorter, lighter carries but may cause discomfort with heavier loads or on long portages. The Expedition’s 840-denier fabric is thicker than the Transporter’s 630-denier shell, yet our tester found the Transporter’s build superior and more trustworthy. Both bags carry an IPX7 rating, but the Transporter’s zipper feels less likely to pop open. And while the Transporter’s single pocket is underwhelming, it still outshines the Expedition, which has no interior organization at all. If you can spare an extra $40, the Transporter delivers a higher-quality product with better features. For more, read our Expedition DriDuffel Dry Bag review.
If you’re heading out on a river trip or into a notoriously wet climate, the Transporter Waterproof will keep your gear dry in even the soggiest conditions. However, it’s more difficult to use than traditional duffels, and its steep price makes it a tough sell for anyone who doesn’t need full waterproofing.

The Panga’s calling card is its completely waterproof design, but another major benefit is its rock-solid durability. This is a duffel for rafting down the Grand Canyon, although its carrying comfort leaves much to be desired, especially at this price.

The Expedition DriDuffel is for river rats and watersport enthusiasts who like a simple, bare-bones approach to keeping their things dry. Its minimalist build is easy to open and offers plenty of space for your gear, but it falls short of the build quality and organizational perks of other waterproof duffels.

If you’re hauling gear through rivers, rainstorms, or anywhere else your bag might get soaked, the Osprey Transporter Waterproof 70L is a reliable option that carries well over long distances. It’s not the easiest duffel to pack or carry by hand, and the pocket setup leaves a lot to be desired, but its waterproofing is legit, and its decently rugged build earned our trust. It’s not cheap, but if you spend a lot of time around water, this bag might be worth the investment.
