Product Customer Reviews

It's good, but if there was one thing that would make it better, is having a 2 way zip on the larger outer pocket. Stuff falls out when you open it. Also I unfortunately got given the old water bladder and styling which isn't what was advertised or I think as good.
Great hydration backpack for long cycle rides.
Good price and capacity
Very convenient, lightweight, easy to pack and to handle. perfect size!
This is ideal for cycling lightweight comfortable and has load of pockets for storage loads of room to pack for items
Just the right size to carry enough fluids & also all your cycling essentials
Bought for my husbands birthday and hes over the moon with it. Great size, comfortable to wear and the hydration pack is great
Superb piece of kit and I actually couldn't believe this was only £30.00 in UK after trying it. The 2L hydration pack reservoir and tube are great for longer rides when the 1L mounted downtube-bottle isn't quite enough. Good quality and feels like it will last. Plenty of space for a spare Tube, Waterproof jacket, First Aid, Phone, Keys, Lube, Allen Keys, tyre pump with the Hydration pack filled to 2L. Alongside all that, was able to fit a Giro Switchblade Chinbar, so perfect for Enduro and XC riding. Waist straps and chest straps fit well. Only downsides are; I'm not sure on how well waterproofed it is, so may consider buying a cover for it. If you fill the Hydration pack up full, the pack sits very straight against the back instead of flush. Not a major problem as it's still comfy enough but that's probably where the more expensive Camelbaks pull away. Otherwise, Its absolutely superb for the price, looks and functions like something £50 more. Don't bother buying a Camelbak unless you want extra comfort and perhaps better waterproofing. This has about 90% of a Camelbak's features for a fraction of the price. It's won MTBR awards for a very good reason, outstanding value for money!
You will struggle to find a better piece of kit. The price is an absolute bonus! Classic Decathlon brilliance
Been using it for almost a year now. Plenty of water for rides and the bladder is designed well which makes it easy to clean. Plenty of other storage for bits & pieces. Love using this pack.
Utterly disgusted to have taken delivery of a USED item - Water still inside the bladder and hose, with a dirty mouthpiece and hair/debris inside the pockets. Given the current pandemic which is spread by droplets of saliva this is honestly the worst experience I've had buying online. How this was not checked during the returns process is beyond me.
Only used once so can’t really comment
I love this bag so much that I don't only use it when I'm out on the MTB, I use it all the time on days out. It is the perfect size for keys, phone and purse, plus other bits and bobs. Sure you couldn't fit a change of clothes, lunch etc in it, but for a morning out or a ride on the MTB, it is the perfect size and it doesn't make your back all sweaty. It is very good quality, I am very happy with it.
I cycle for about 5 to 6 hours each time 3 or 4 times a week and it holds my water snacks and repair kit very well.
A really well thought out pack. Just the right size for carrying a pump, multi tool and a few spares and room for a waterproof top, however the zip has failed on mine after not a huge amount of careful use

Peter, Cycling Manager, DECATHLON
