The MARCHWAY 30L Floating Backpack beats the HEETA 5L for most paddlers with its larger capacity, padded straps, and float safety.
The Verdict
Best for most people
MARCHWAY Floating Waterproof Dry Bag Backpack (30L)
Its 30‑liter capacity swallows a weekend’s worth of gear, padded straps carry the load comfortably, and the floating design saves your pack if it takes a swim.
Pick the HEETA Waterproof Dry Bag (5L) with Phone Case instead if
- You’re a minimalist day‑tripper — the HEETA’s compact size and included phone case are all you need.
- You paddle a small kayak with tight hatch openings — the HEETA’s slender roll fits easier.
- Budget is the top priority — the HEETA costs less than half the price of the MARCHWAY.
- You need quick phone access — the HEETA comes with a separate waterproof phone pouch, while the MARCHWAY doesn’t.

Capacity — MARCHWAY takes the lead
The MARCHWAY’s 30‑liter main compartment dwarfs the HEETA’s 5‑liter pouch. You can roll a full change of clothes, a camp towel, snacks, and a water bottle into the MARCHWAY and still have room. The HEETA, meanwhile, forces you to choose between a jacket and your lunch — a real limitation on longer outings.
For paddlers who need extra space, the difference is stark. Kayakers and canoe campers routinely report stuffing tents, sleeping bags, and cook kits into the MARCHWAY, while HEETA owners say they use it as a personal electronics bag only. If your trips ever exceed a few hours, the MARCHWAY’s capacity is non‑negotiable.
Carry Comfort — MARCHWAY wins with backpack straps
Padded shoulder straps transform the MARCHWAY from a simple dry bag into a wearable pack. Over 34,000 reviewers praise the comfort during portages and hikes. The HEETA’s single shoulder strap, in contrast, begins to dig after a 15‑minute walk — a trade‑off for its ultra‑light design.
The MARCHWAY’s straps also let you go hands‑free. Whether climbing into a kayak or scrambling over rocks, having both arms free is a safety advantage. The HEETA must be hand‑carried or slung awkwardly, which can become a nuisance on uneven terrain.
Flotation — MARCHWAY adds a safety net
One of the most common fears on the water is dropping your bag overboard. The MARCHWAY floats, even when fully loaded, giving you precious time to retrieve it. The HEETA, without any flotation, will sink immediately — a costly mistake if it’s your phone that’s inside.
For whitewater rafting or capsizing-prone trips, the float feature is a game‑changer. Many verified buyers report watching their MARCHWAY bob on the surface after an accidental spill, while HEETA owners caution to tether the bag at all times. If you paddle anywhere deep or fast, the MARCHWAY’s floatation buys valuable peace of mind.
Waterproof Phone Protection — HEETA wins with an included case
The HEETA ships with a separate transparent waterproof phone case, which the MARCHWAY lacks. This small accessory lets you take photos, check maps, or reply to messages without exposing your device to spray. For day‑trekkers who rely on their phone for navigation, this is a genuine advantage.
However, the phone case is only effective if you remember to seal it. Complaints about fumbled zippers and foggy photos appear in some reviews, but when used correctly, the HEETA’s case keeps a phone dry even during a brief dunk. The MARCHWAY forces you to buy a separate waterproof pouch, adding a few dollars and an extra item to your kit.
Packability — HEETA wins for portability
The HEETA rolls into a cylinder smaller than a coffee thermos, while the MARCHWAY remains bulky even when empty. If you often paddle a tight sit‑inside kayak or ride a bike to the put‑in, the HEETA’s compact shape slips into a hatch without a fight. The MARCHWAY’s stiff fabric and padded back panel resist squishing.
But the HEETA’s packability comes at the cost of any structure. It’s essentially a stuff sack — great for shoving into a backpack, less great for carrying on its own. The MARCHWAY, by contrast, keeps its shape and even has a small outer mesh pocket for wet items.

Frequently Asked Questions
HEETA 5L vs MARCHWAY 30L: which is better overall?
The MARCHWAY 30L Floating Backpack is the better all‑around dry bag for most people. Its 30‑liter capacity, padded backpack straps, and ability to float if dropped in the water make it far more versatile than the HEETA, which is limited to very short trips and light gear. The HEETA wins only if you exclusively paddle for an hour or two and want the smallest possible bag.
Is the MARCHWAY 30L worth the extra cost over the HEETA?
For any trip that lasts more than a couple of hours, yes. The MARCHWAY costs roughly twice as much but gives you five times the capacity, plus backpack‑style carry and floatation — features that directly impact convenience and safety. The HEETA is the better deal only if you never need to carry more than a phone, keys, and a light jacket.
Does the MARCHWAY really float with gear inside?
Yes, the MARCHWAY is designed with trapped air that keeps it afloat even when fully loaded, according to thousands of verified buyer accounts. It will bob on the surface if it goes overboard, giving you time to grab it. The HEETA does not float; it will sink immediately if dropped in deep water.
Can I use the HEETA 5L as a daypack for hiking?
The HEETA is ultralight and waterproof, but its single shoulder strap makes it uncomfortable for long walks. It works fine as a stuff sack inside a backpack, but if you plan to carry it on your back for more than 15 minutes, the MARCHWAY’s padded straps are a much better choice.
What if I already have a waterproof phone case?
Then the MARCHWAY becomes an even stronger pick. The HEETA’s main advantage is its included phone case; without that need, the MARCHWAY’s larger capacity, backpack straps, and floatation make it the clear winner for any trip beyond a quick paddle. You can still buy a separate waterproof phone pouch and clip it to the MARCHWAY’s shoulder strap.
Will the MARCHWAY fit in a small kayak hatch?
The MARCHWAY is bulky, even when empty, because of its thick fabric and padded back. It may not squeeze into the narrow hatches of sit‑inside kayaks. The HEETA rolls down to the size of a Nalgene bottle and fits easily. Measure your hatch opening before choosing a larger dry bag.
