The hydration pack 920 is as expected, excellent.

Strong, well made and, ideal for the kit that needs to be carried.

A good bag

I bought this after seeing a friend buy it. I thought, 3 litres is a lot, just what I need, so I bought it mainly for that, but once I had it on my back, the extras are well worth the cost. It has a nice strong metal clasp at the front, suitable for a sports camera (once you mount the adhesive pad. There is room for everything you need. Pockets everywhere, even on the waist straps. Just don't over fill it, it can get heavy!

Very secure

An excellent sack with hydration bladder, fold away rain cover and helmet storage, all for a reasonable price.

Nice bag

Purchased this bag mainly for the commute to work. I wanted a decent sized bag and this is plenty big enough, but with the adjustable straps the bag can be tightened to keep it slim when I don't need to fill it. Really comfortable to wear, whilst I'm riding I hardly feel it. Overall really happy with my purchase.

Super Bag

Excellent bag & well thought out pockets in front for snacks tool section opens 180 for ease of access as does the main compartment, hydration pocket has a solid divider which helps keep your fluid cool against your back but is very comfortable. The bag is a solid and snug fit of which the main buckle has a spot for sticking a camera mount.

hydration pack 920

Initailly really liked the bag, great sized bladder and loads of pockets and not much bigger than a normal pack. However it has issues. Chest adjusting straps loosen themselves while riding so needs constanly tigthening up to fit snuggly. Bite valve is very stiff, needs two hands to open, hurts your teeth if you try to do it that way, cant leave it open or it drips all down you. The hooks to keep the helmet pouch closed are a poorly thought out idea, as they can and do open themselves when the bag is moving around while riding. Front buckle is not all metal, and after a small crash the plastic side where the strap threads through has snapped at one side. Still holding together but its only a matter of time before the other edge breaks then the bag will be useless.

Dear Sir,
Thanks for giving us such a detailed description of your experience with the bag. All the points are very interesting and I have forwarded them on to the product manger at b'Twin today.
If the clip does break, please don't hesitate to return the bag to us.

BTwin hydration pack

Only used it twice due to a bad back, but both rides were fine. Love the waist pockets for keys/cash and the chest strap stops underarm rubbing, neat! Ideal for short or longer rides. Very happy as I'm a backpack/rucksack "nut" and have had about 30 or so. This fits the bill for everything I need it for, Mtb rides in North Wales etc. Perfect so far!

720 hydration backpack

Value for money compared with other brands. Plenty of room for storage. Love the harness and space for a go pro camera mount. Good size bladder with a secure fastening.

Las cremalleras llegan tan abajo de los laterales de la mochila que cuando la abres se pueden caer objectos de dentro. La cinta del pectoral incordia si llevas pulsometro. El casco no queda bien asegurado y se puede caer.

Gracias , pasaremos esta información a los jefes de producto para poder mejorar en el ,

Muy cómoda y espaciosa

Me gusta sobre todo su capacidad con varios espacios espacios separados para llevar cosas, por su peso ligero, y porque va muy acolchada a la espalda pero dejando huecos para la transpiración. Por otra parte el cierre de pecho es ancho, resistente y muy cómodo. Una gran compra.

Bueno pero con demasiadas cosas malas

El principio la mochila es muy chula, mucho espacio para guardar cosas, una bolsa de 3L. Una hebilla para colocar el soporte para una cámara de acción. Un espacio para guardar el casco y además es bonita. Punto muy positivo el cruce de las asasque permiten dejar los hombros con mas movilidad que una mochila convencional. Para Enduro o descenso es un MUST. Ahorra viene lo malo: - el espacio para el casco esta mal pensado para un casco normal pero si lo que tienes es un integral esa machina no te vale. - los bolsillos internos se comunican por abajo. Eso quiere decir que con dos veces que te lo pongas h te lo quites y todo estar a mezclado en el fondo - al precio que tiene esperaba unos tejidos algo más duros. - lo peor los bolsillos laterales, están hechos de un material tal malo que en una sola salida sin caída y uno de ellos está completamente rajado, me imagino que por contacto con ramas - Otro punto negativo es el ancho del cinturón, es demasiado estrecho y hace que no sea cómodo. El problema es que por la forma q tiene la mochila es imprescindible atarla.. Una vez más no entiendo que un producto así vea la luz. Me compré la más cara esperando algo de buena calidad y estoy decepcionado que falle por usar calidades de tejidos tan bajos. No creo que Decathlon haya probado el producto final antes de venderlo.

Perfecta para su cometido

La mochila tiene un tamaño ideal para las salidas en BTT más largas. Te permite llevar todo lo necesario de forma muy ordenada. Utiles los bolsillos con cremallera del cinturón. En mi caso la pieza de union de los tirantes no me ha sido molesta y el ajuste es muy bueno. Los creo 14l de capacidad anunciados se alcanzan con el bolsillo para el casco y esto es lo único que debes tener en cuenta. Muy positive que lleve incluida la bolsa de hidratación.

The rockrider all-mountain hydration pack has a story...

Since it is important to carry water and equipment during all-mountain rides, we have tested this Rockrider MTB AM hydration backpack with all-mountain riders on various terrains and MTB trails and in different weather conditions.

How do i clean my bag and water bladder?

For the water bladder: After each outing, rinse and dry the hydration bladder. Use the brush and dryer cleaning kit (item 631 585). For the bag: The pack can be hand-washed with a sponge and soapy water.

For your night-time mtb rides

This product has a attachment for attaching a VIOO Clip, an LED light that can be clipped on and off anywhere in an instant. Red or white lighting in continuous or flashing mode depending on your choice, with the VIOO Clip lights you are clearly visible from up to 120 metres. Battery life is 9 hours in flashing mode, 4½ hours in continuous mode. Easy to recharge via a USB cable (sold with the VIOO Clip).

Bring with you...

This hydration pack comes with a 3 L water bladder. But also remember to bring: - your food (granola bars, energy gels, etc.) - your multi-function adjustment tool (ref: 8386669) - a puncture repair kit (inner tube, tyre lever, hand pump, puncture repair spray, CO² cartridge, etc.) - your chain rivet extractor and a quick link - a piece of identification, blood type card - a means of payment and a telephone - a 1st aid kit - etc...
