fangzi 105L Paddle Board Backpack review

Have you ever struggled to find a travel backpack that actually fits an inflatable paddle board and everything else I need for a day on the water?

My review of the fangzi 105L Paddle Board Backpack Waterproof Large Capacity Portable Oxford Cloth SUP Surfboard Bag, White

I bought the fangzi 105L Paddle Board Backpack Waterproof Large Capacity Portable Oxford Cloth SUP Surfboard Bag, White because I needed a simple, durable solution to transport my inflatable SUP and accessories. I wanted to test its capacity claims, comfort while carrying heavier loads, and how well it protected my gear during transit.

First impressions and unboxing

When I first took the bag out of the shipping box, I noticed it was lightweight and compact in its packed form. It came folded flat and felt well stitched at the seams; the material had a slightly waxy finish that suggested some weather resistance. I appreciated that it was uncomplicated—no unnecessary add-ons—just a large simple bag meant for a board, pump, and a few extras.

Capacity and how much it really holds

The 105L rating is impressive on paper, and in practice it translates to a very generous internal volume. I can comfortably fit a 10’6” inflatable SUP deflated and rolled, plus a compact pump, a coiled leash, a repair kit, and a handful of small items like water shoes, sunscreen, and a dry bag for my phone. If I pack more carefully and use compression, I can even add a lightweight change of clothing or a towel.

Because the dimensions are broad (94 x 40 x 28 cm), there’s room for boards at a range of sizes; however, very large or rigid boards won’t fit because this bag assumes you’re carrying an inflatable SUP. If you own multiple SUPs, I’d recommend testing how your particular model compresses before relying on the bag for long trips.

Material, build quality, and seams

The exterior is Oxford cloth with a PVC lining—this combination gives the bag a balance of lightness and toughness. The exterior fabric resists abrasions and the PVC helps with water resistance on the interior. The zipper and seams seem reinforced where it matters most, though I did notice that the stitching around the carrying straps could be improved if I were to load it to maximum capacity daily.

After multiple trips, the fabric held up to sand, saltwater splashes, and the occasional snag on boat rails. I treated the bag with a fabric protector spray for extra longevity, which helped in repelling water and preventing stains. For me, the construction feels good for recreational and frequent use, though heavy commercial or airline baggage handling would be more stressful for the seams than typical personal travel.

Zippers, closures, and access

The main zipper runs along the top and down one side for easy access. I appreciate that I can open the bag widely to slide the packed board in without wrestling it around corners. The zipper pull is big enough to grab with wet hands, and a flap covers much of the zipper to reduce water intrusion.

There’s no complicated locking system or multiple zipper compartments—this is a straightforward design. If you like lots of pockets and organizational compartments, this bag won’t satisfy that need. For me, that simplicity is a benefit, since I can stow bulky items without dealing with small interior pockets that might take up precious space.

Comfort and carrying system

At just 800 g, the bag itself is very light. The shoulder straps are padded and adjustable, and there’s a sternum strap that helps stabilize the load when I’m hiking to a launch site. I often carry the packed bag for 10–20 minutes over mixed terrain, and the straps distribute weight fairly well. I did find that after prolonged walks the padding could be thicker for heavier loads; for long hikes I pair the bag with a cushioned waist pack to reduce lower back strain.

The backpack-style carrying makes hands-free transport easy, which I value when carrying a pump or a child’s gear at the same time. There’s also a grab handle at the top that’s handy for short lifts or when I need to move the bag into a car.

Weather resistance and waterproofing

The Oxford cloth and PVC lining offer good resistance to light rain and sea spray. In short, wet conditions I have not had water soak through to the board or accessories. That said, this bag is not fully submersible, and I wouldn’t leave it exposed to heavy downpours for hours without additional protection.

I tested the bag in a rainy afternoon: water beaded and mostly ran off, and the interior stayed dry. For extended storms, I recommend adding a rain cover or placing delicate items in a secondary dry bag. The PVC lining provides basic protection from moisture, but seams and the main zipper are potential wet points if fully exposed.

Portability and travel convenience

Because it folds down to a compact package (41 x 33 x 2 cm), the bag is great for storing in a car trunk or tight cupboards. I also appreciated that it’s light enough to add to checked luggage if needed. The internal volume and ability to compress the contents makes it a good companion for weekend trips.

For airline travel, check airline carry-on and checked luggage policies—the bag itself is the right size to be a carry item when empty, but once packed it may exceed carry-on dimensions depending on the board and accessories inside. I personally pack the inflated board in a separate bag for flights or contact the airline ahead of time.

Real-world performance: loading, unloading, and transport

When I first loaded my inflatable SUP, I rolled it tightly and started with the fins removed. The board slid into the bag without catching on the edges because the bag’s interior is roomy. Loading the pump and small accessories into remaining spaces worked well; the bag feels like a single large compartment deliberately designed for bulk rather than organization.

On car trips, I placed the bag on the back seat or trunk, and I noticed minimal shifting because the bag can be compressed tightly with cargo straps. When I carried the bag on foot, the wide straps and sternum clip prevented the contents from swinging. Overall, performance during transport has been reliable and low stress.

Durability after months of regular use

After several months of frequent use—weekend paddles, beach days, and a short road trip—the bag showed only minor wear. Scuffs on the exterior were cosmetic and didn’t compromise functionality. The seams held up well, although I remain cautious about overstuffing to the point where zippers strain.

I did condition the bag with a fabric protector and occasionally clean sand and salt out with fresh water; this maintenance likely contributed to keeping the bag in good shape. If you plan heavy-duty daily use or commercial rentals, I suggest reinforcing stress points and monitoring the zippers and strap anchors regularly.

Storage and packing tips I’ve learned

I pack the largest, bulkiest items first—the board, pump, and a rolled towel—then wedge smaller items into corners. Removing fins and deflating the board as much as possible helps. I also place fragile electronics in a separate dry bag inside the backpack so I don’t worry about splashes or moisture near the zipper.

I keep a small carabiner attached to the exterior strap and use it for quick items like a water bottle or keys. When storing the bag long-term, I let it air dry fully, then fold it loosely to avoid creasing the PVC lining.

Pros and what I like most

• Large 105L capacity that handles a deflated SUP and accessories with room to spare.
• Lightweight at 800 g, making the bag easy to carry or store when not in use.
• Simple, functional design that prioritizes space and ease of access.
• Durable Oxford cloth with PVC lining offers good resistance to abrasion and light water exposure.
• Comfortable padded shoulder straps and sternum strap for short to medium treks to launch points.
• Compact folded package size makes it convenient for travel and storage.

Cons and areas for improvement

• Not fully waterproof—vulnerable at seams and zipper if fully exposed to heavy rain or submersion.
• Limited internal organization; no built-in pockets mean small items can shift unless I use pouches.
• Strap stitching could be beefed up for very heavy, daily commercial use.
• White color shows dirt more readily than darker colors, so it needs more frequent cleaning if I’m beaching it often.
• Not ideal for rigid boards or very large SUPs that don’t compress well.

How it compares to a couple of alternatives I considered

I compared this bag against two other common solutions: a rigid padded SUP travel bag and a standard duffel with a waterproof liner.

• Versus a rigid padded travel bag: The rigid bag offers more protection during airline travel but is heavier and bulkier when not in use. The fangzi 105L is lighter, easier to store, and better for road trips where I can pack the board carefully.
• Versus a standard duffel with waterproof liner: The duffel is cheaper and flexible, but often lacks the right shape and strap configuration for comfortable backpack-style carrying. The fangzi bag is purpose-built for SUPs and is more ergonomic for hikes to launch points.

For my use—casual paddling, road trips, and beach days—the fangzi 105L strikes the best balance between portability and protection.

Who the fangzi 105L bag is best suited for

I recommend this bag to weekend paddlers, recreational users, and road-trippers who need a lightweight, roomy, and durable bag for their inflatable SUP. It’s great for people who prioritize packability and ease of carrying over rigid protection. If you’re a frequent flyer with heavy airline handling, you may want something with additional padding or a harder shell.

Practical scenarios where I used the bag

• Beach day with family: I packed the SUP, pump, leash, a small cooler, and towels, and it fit comfortably. Carrying the bag to the shoreline was easy with the backpack straps.
• Overnight road trip: I placed the bag in my trunk and used cargo straps to secure it. The bag compressed well and didn’t shift during driving.
• Quick urban commute to a lake: The backpack straps let me walk hands-free to the water with the pump clipped to a strap.

These real-world uses helped me evaluate weight distribution, access, and weather resistance in everyday situations.

Maintenance and cleaning routine I recommend

I rinse the bag with fresh water after beach trips to remove salt and sand, then air dry it fully in a ventilated area to prevent mildew. For stubborn dirt, a gentle brush and mild soap work fine on the Oxford cloth. I avoid harsh detergents that can degrade the PVC lining. Periodically treating the fabric with a water-repellent spray keeps the bag performing well in wet conditions.

Store the bag loosely folded in a cool, dry place away from direct sunlight if you won’t use it for extended periods; prolonged UV exposure can degrade fabrics over time.

Packing checklist I use for trips

I keep a short checklist to make packing easy and efficient:

• Deflate and roll SUP, remove fins
• Place board in bag first
• Pump and hose in next
• Leash, repair kit, and tools in a small zip pouch
• Clothing and towel rolled tightly and added to gaps
• Electronics in dry bag and placed centrally
• Final compression and secure zipper

This routine helps me avoid forgetting important items and makes loading faster.

Troubleshooting common issues

• If the zipper sticks: rinse with fresh water, apply a dry lubricant such as silicone spray, and work the zipper gently back and forth.
• If straps begin to fray: re-stitch or reinforce with strong fabric glue and additional material patches.
• If interior gets damp: remove contents, hang bag open to dry thoroughly, and place silica gel packs inside during storage.

I’ve used these fixes myself and they’ve prolonged the bag’s usable life.

Frequently asked questions (FAQ)

Q: Can it hold a 10’6” inflatable SUP? A: Yes, most 10’6” inflatable SUPs will fit if rolled and deflated properly. The bag’s dimensions are generous enough for common board sizes.

Q: Is the bag fully waterproof? A: No. It’s water-resistant due to the Oxford cloth and PVC lining, but seams and the main zipper are not fully waterproof. Use a dry bag inside for valuable or sensitive items.

Q: Will the white color stain easily? A: White shows dirt more than darker colors. I recommend rinsing sand off soon after use and cleaning periodically to keep it looking fresh.

Q: Can I store a pump and fins inside? A: Yes, a compact pump, hose, and small items like fins and repair kits fit easily.

Q: Is this suitable for airline travel? A: It depends. For checked luggage with careful packing, it can work, but for frequent airline travel with rough handling I’d consider a more heavily padded or rigid travel bag.

Accessories I recommend pairing with the bag

• A small internal dry bag for phone and electronics.
• A pump bag or pouch to keep hoses organized.
• Reinforced strap covers if you carry heavy loads frequently.
• A rain cover for extended or heavy rain exposure.

These accessories make the basic bag function more like a complete travel system and help protect smaller fragile items.

Personal safety and ergonomics tips

I always adjust straps so the bag sits high on my back, close to my center of gravity. I use the sternum strap to steady the load and muscles, and I take short breaks if I’m walking long distances. For heavier loads, I add a padded hip belt or transfer some items to a waist pack to avoid lower back strain.

What surprised me most

I was most surprised by how roomy the interior felt despite the bag’s relatively compact packed size. The 105L specification isn’t just a marketing number; it really does translate to usable space for a typical inflatable SUP plus accessories. I also appreciated how quickly the bag dried after rinsing.

Overall verdict

I like the fangzi 105L Paddle Board Backpack Waterproof Large Capacity Portable Oxford Cloth SUP Surfboard Bag, White for its intended purpose. It’s a thoughtfully designed, lightweight, and spacious bag that does the job for recreational paddlers and weekend travelers. While it’s not a heavy-duty, fully waterproof option for extreme conditions or commercial rentals, it provides excellent value and functionality for most users.

I would recommend this bag to anyone who wants a straightforward, portable, and reliable way to transport their inflatable SUP without fuss. If you prioritize lightness, storage efficiency, and simplicity, this bag likely fits your needs. If you need maximum waterproofing or rigid protection for airline handling, consider adding protective measures or looking at a more specialized travel case.

If you want, I can summarize my top tips for packing this bag in a short checklist or help you compare it to a specific model you’re considering.
