- Highest-level US Raw TPU (Polyurethane): The ITRAZ water bladder tank is crafted from high-density TPU-coated mesh fabric, ensuring environmental friendliness. It is 100% food-grade, non-toxic, BPA-free, DEHP-free, PVC-free, and odorless. This design prevents any impact on the taste or smell of water, distinguishing it from PVC and plastic tanks. Specifically designed for supplying RV fresh water or long-term home water storage.
- Foldable, Durable, and Reusable: This tank is highly space-efficient, reducing its size by over 92% both before and after use through easy folding and storage. When filled with water, it can support a weight exceeding 2204 pounds or withstand a fall from a height of 39 inches without leaking. Its lightweight nature makes it easy to carry in a backpack or car for various outdoor activities, such as RV water storage, camping, road showers, rainwater collection, irrigation, hurricane and drought.
- 304 Stainless Steel GHT Threaded Outlet/Inlet: The outlet/inlet is constructed with 304 stainless steel, known for its wear resistance and high hardness. This metal fitting is significantly more durable than plastic fittings. The 3/4 GHT Thread is compatible with standard garden hoses, ball valves, pump and RV water filters, facilitating activities like car washing, plant irrigation, and outdoor water purification and storage system building.
- Engineering-grade Fixation System: The ITRAZ water bladder tank features a unique fixation system with four high-density nylon straps equipped with stainless steel D-ring buckles. This specialized structure, widely used in engineering, can withstand a tensile force three times its own weight. You need to use ratchet straps connected to the D-rings to secure the water bladder to the truck bed, preventing shifts in the center of gravity and ensuring safety when driving on any terrain.
- Package Included: The water bladder tank package includes: 1TPU Water Bladder Tank, 2Ball Valves, 2Silicone Gaskets, 1Teflon Tape, 1 TPU Repair Patch, 1 Wrench, 1 Product Instruction.

Well Made
Color: Blue
Size: 60 Gallon
Nice bladder that works great. The fittings are top quality and well positioned. I used it with a 12V pump for fresh water when camping (watched all the others carry 2 gallon pails in wagons to get water). Be smart...get this to have water for your camper or campsite.

Great, watch out for over twisted spouts.
Color: Blue
Size: 35 Gallon
Fantastic ability to transport water. Had an issue with first bladder being having broken leaking spout on both sides. Returned for replacement and received second bladder in good time with now issue and working perfectly for our needs. I would’ve given it four stars if the first bladder did not have broken, spout other than that this bag is tough supports 30 gallons of water and is being used on a daily basis with no issue.

THIS is the one you should buy!!!
Color: Blue
Size: 35 Gallon
I've tried 9 different water bladders of similar size. All of the others leaked or failed immediately. This is the best water bladder i have found readily available, and i was gobsmacked by the outstanding quality!! The rf welded seams are perfect, the tpu is excellent quality and uniform thickness. The valve ports are well made and do not leak. I am not 100% sure how easy it will be to replace the rubber washers in 7 years when they start to degrade, but im pretty sure it can be done with a bit of patience, which is amazing that this is a serviceable design. None of the other bladders have serviceable or replaceable valve ports. Check the port tightness when you receive the bladder, but mine were pretty good. Another thing that shocked me...this bladder comes with two stainless ball valves!! The are 3/4ght connections. It even comes with 2 stainless caps, 1 male, 1 female. I use this bladder for week long overlanding trips, and i write this after returning from a week long beach trip, where we had the perfect amount of water for drinking, cooking, cleaning, and showers for 2 people over 5 days. We returned with 2 gallons left. I attached quick connect fittings to be able to pop on my pump and shower system, and we feed the shower system from the top port, while using the bottom port for a sink tap. I was going to run a permanent fill port through the quarter panel of my jeep, but its honestly not necessary as the ports are placed perfectly!! Every other bladder puts the top port in the center, which is not conducive to easy use. This one is at the front right corner! The strapping helps create structure and rigidity on a flexible bladder that would otherwise roll a bit. It also gives an anchor point for holding it down in the vehicle. Dont waste your time with other bladders 1/3 the price that leak or dont quite work how you would hope. This company makes an exceptional product at a very very reasonable price for the quality of the product. This is the bladder you want if you plan on using it constantly! Also, because it is tpu, it doesnt hold that funky plastic smell or taste, it adds nothing to the water, which is great when using it for potable drinking water. This is unreservedly one of the best if not the best overland water bladders on the market!

A chain is only as strong as its weakest link. Leak at lower outlet.
Color: Blue
Size: 60 Gallon
I used it for the first time today. It leaked from the bottom opening. The seal was not secure, and the outlet spins. As luck would have it, the return window closed yesterday. I guess my planning ahead was a day to early. A chain is only as strong as its weakest link. Unfortunately, since this is the lower opening, the bladder is almost useless. I will update my review if the seller responds.

Top notch, super useful water bladder/storage
Color: Blue
Size: 35 Gallon
Worked out great just as anticipated. Will be very handy in case of emergency and especially out on my next camping trip. If you're wondering about actual dimensions when full to build a solid enclosure for it - mine is 34.5"L x 22.5"W x 16"T but I would suggest taking your measurements to be 100% sure. Sat for 3 days w lines attached and zero leaks.

Not Specified Capacity
Color: Blue
Size: 35 Gallon
I ordered the 35 gallon. It appears to be good quality but is not 35 gallon. The bladder that I received does not indicate its capacity. It fills my 27 gallon camper tank about 2/3 full, so I would put it at about 20 gallons. That works for me. but if that wouldn’t work for you, you may want to double check the capacity of the bladder that you received.

Well built
Color: Blue
Size: 35 Gallon
Super impressed. I use it to haul water to a property where we don't have water yet. Fill a RV, water plants, etc. You can use a hand pump or electric pump to move the water quickly, or gravity feed depending on where the water is going. It seems quite well built, thick material, few valves to install, and it's ready to go. One trick, try to keep it air tight without air in the bag. If you fill it from the bottom port (which is probably not normal), you can vent the top to allow extra air out.

The valves look very professional but do not seem to be very long lasting.
Color: Blue
Size: 60 Gallon
This is a possibly a wonderful 'cool' looking, great chrome valves for letting water in or out but I wish they would have spent some time actually using the devices. /s To start with when I first got my 60 gallon model, one of the valves that screw into the bag were loose and leaking. Luckily the company left a way to tighten up the valves in case of this problem (including the wrench needed). Now when I 1st got the 60 gallon bladder, it seemed OK for a few weeks. They 'appeared to use very well made valves to turn on and off the needed areas as you fill, dump, or refill. Unfortunately it appears to be all shiny and pretty but just does not last after a while. I am replacing my valves with some plastic/have always worked Gilmour adapters I have used for years. I will notify the company or Amazon and let them know the problems I have had And I am sure they will send me another valve which might or might not last very long. I have had a 60 gallon Aquatank 1 for well over 8 years until a seam blew out in the desert here. So I thought I would try one of the "New" blue bags with fancy valves on it.
