Maelstrom Hydration Hiking Backpack with 2L/3L Water Bladder, High Flow Bite Valve Water Backpack for Men Women Lightweight Insulation for Hiking, Cycling, Running, Climbing, Camping

I purchased this day pack for a recent trip to the Death Valley national park. It is a well-constructed day pack that comes with a water bladder. The water bladder - I ordered the 3L version. It is easy to fill water and also to attach the bladder to the velcro in the pack to secure it. The bag/tube does not have any weird plastic smell. The long drinking tube disconnects at the bottom the bladder and it has a cover that keeps the bite valve clean. The bite valve could be shut off with a simple twist. The materials seem pretty decent. The pack itself is not very big but it does contain a lot of zippered compartments. A large mesh pouch with straps at the very front could hold a wind breaker or puffer jacket (not big though). The pack has waist straps (narrow, not too comfortable), thick padded shoulder straps (very comfortable), and two chest cross straps. The back plate is slightly stiff to improve ventilation. Overall, I'm very pleased with the quality, functionality and price point of this pack. My only concern is whether this comply provides the same level of post-sale services as other elite outdoors ware companies. In particular, the silicone bite valve sheath will eventually fail and hopefully replacements are readily available.

I bought this to take with me on a 25 mile bike ride. It worked great. I got this one because it had a larger bladder and a ton of pockets. I was worried it would be too heavy, and while it is heavier than a slimmer bag would be, it wasn’t a problem. It was just as easy to use as the name brand ones. It was comfortable and never bothered or irritated me during the ride. I plan to use it for anything I take my kids to as it’s a little easier to carry around than a giant water bottle or container.

I bought this as a replacement for my more expensive name brand bag/water backpack. This was much cheaper. The very first thought I had when I ordered it was oh well it's probably going to feel cheap but what do you want for half the price? Whenever I got it I was very happy with my purchase. I got the one that holds 2 l of water and I really like the way that it functions. The water pouch part of it is kind of standard. What makes this stand out is the bag itself has a liner inside of it that keeps your drinks cool for up to 6 hours, and yes it actually works. Especially if you throw in some ice in the bag with your water. The parts that touch your body as far as straps and the back piece go are all padded and have a material on top of them that should dry sweat pretty quickly. It does have adjustable straps for your chest and for your waist as well to keep it tight to you. The bag itself is much larger than my previous one. It has plenty of pockets and zippers even a flip down piece that can be used as a helmet storage if you are like me and ride mountain bikes and one Wheels. I actually took this thing camping last weekend and I carried my clothes and everything I would need for the trip as far as toiletries, medicine, first aid, a Sony camera, even a backup pair of flip flops all fit easily in the bag. It has several clips, d-rings and bungee cords for carabiners and extra storage. It has adjustable straps to keep things nice and tight when packing for a trail ride or hike, or to open up and fit larger items. I am really impressed by the deceptively large size of this big. With all the straps pulled tight and the bag empty, you would never guess it would hold so much. Great price point too

Great pack with comfortable fit. Pockets are well thought out and have a use for everything. The hydration pack with a nozzle cover is a big plus. The hip strap is the only problem. It does not fit properly but can be fixed by looping the straps through each other.

Seems very well built especially for the price. Comfortable to wear. I am 280 pounds and 5’8” and the front straps are plenty large enough to accommodate me. Hydration bladder as advertised. Lots of pockets.

Great bag for a budget price. Hydrating bag works as intended. Feels comfortable for a bigger person (280 lbs)

I love this bag. This is my light/summer work backpack. I work outside and carry my hand tools in this while also carrying 3 liters of water in an insulated pouch. Even at 95 degrees, my water stayed cool for a few hours. The pockets everywhere allow me to keep my hand tools organized.

Overall a functional backpack with good storage and comfort. The bladder and hose work well with the extra shutoff valve, but has been difficult to get the chemical taste out of it. The quality is based upon my first use (after return period) the lower waist strap pulled out of the stitching rendering the lower strap useless. It appears that the strap was never sown into the seam like the other side.

The product is very well made and has all the features you could want.

de muy buen material, se siente resistente, es pequeña y ligera, justo lo que esperaba

looks great, will be using it for a 5 day hike so will update after. Better quality than others ive ordered, many pockets

Great bag, well made and looks great. Plenty of room for essentials. Bladder seems good quality and the cooler compartment is ideal
