water bag problem

disappointed by the quality of the water bag which leaked after 11 months at the hose connection.

Very good article

Great product

I was looking for a bicycle backpack for a long time, but I found this hipster backpack. First of all, my back is finally dry. Taking into account the price-quality ratio and comparing to more expensive solutions, this is an ideal product. Many pockets with pictograms to help keep things organized. cool

Freedom of movement

I took this bag out for a 120 km trip, to see how it behaves during commuting. The price is high compared to my 12l backpack or close, but when it comes to the lightness that the bag offers I don't regret a penny. In it I just put my keys, phone, wallet, a stick of peanut butter and the water bottle. Next time I will put the pump, 2 chambers, lever to remove the tire. I have not had any problems with it, abdominal pain in the lower part or others. I adjusted the bag on departure and that was it.

Complicated adjustment, impossible to put it on for thin people. Non-existent pipe holding magnet arrived at home!! Waist too elastic. To improve. Too expensive.

Somewhat expensive compared to top brands

Better than a camel backpack

The only bad thing I find is that little by little it becomes loose and you have to keep pulling on the straps

Great bag, sufficient capacity for both the bladder and the bag itself. Great and intuitive magnetic hook, I don't know how you can have problems with it, I shortened the tube by a few centimeters. I regret that after many years of MTB riding with a backpack, I decided to use this type of equipment so late, my back is dry and generally much more comfortable :-) I only have one bottle holder on my bike, so I wanted a fanny pack with a water bladder. So far, three trips to the mountains, 0.7l water bottle + 1.2-1.3l to the bladder (I will fill it up on a longer route), which was enough for me for a route of ~65km. A proven closure of the bladder and a comfortable mouthpiece with the option of locking are also a plus. You have to get used to it and not tighten the belt too much, the lap belts can be adjusted with one hand while driving. I also took into account more expensive competitors, mainly Camelbak, but it seems to me that this one has better ventilation and the bladder, and in fact closing it takes up less space, and the price is lower. Lots of well-thought-out compartments. My equipment includes: a water bladder, two TPU tubes, a CO2 pump + 3 cartridges, self-adhesive patches, 2 spoons, a clip, 3 glasses wipes (or to wipe the tube before sticking the patch), 1-2 bars + 3 gels (always a little more than I can eat :-), multitool, telephone. Once I took a windbreaker jacket and something else would fit in the main pocket. There is plenty of space for my needs and comfort in every respect. At the moment, I have not noticed any defects and I cannot confirm the defects reported by other users. As for durability, I haven't been using it for a long time, but for now it's ok. I recommend it with a clear conscience, it's my best purchase for many years.

Is super. It fits everything I need + voada and it is beautifully divided.

good, not perfect BUT no spare parts

this pouch is comfortable and costs half as much as the competition, the main flaw if we want is that the water bag has no separation inside the main compartment. my vote, however, is related to the fact that decathlon has stopped selling the water bag itself for almost a year. mine broke and I threw it away and it's impossible for me to buy a replacement.

Great product

First 60 km outing on an AM mountain bike, comfortable in d+/d-, super well compartmentalized, spacious, cool design and very good finish, the fixing system for the cannula is great and all for an aggressive value for money :)
