If the bicycle arose for a reason it was for its day to day functionality. It's obvious that nowadays it's mainly used for leisure, but we mustn't forget its origins. Those of us that use the bike for getting around every day know the importance of the bags and back packs when we need to carry our stuff around, or for just carrying our spares and tools in case our bike has a breakdown. To this end there is a wide range of bags and back packs, for the cyclist as well as the bike.
Since their invention, water bags have revolutionised cycling providing great convenience for hydration. These have a specific compartment for storing the water inside a specific liquids bladder. A simple tube with a safety valve, placed on the outer part of the handle, is what allows us to transfer the liquid from the back pack to our throat without having to bend over to pick up the Water bottle. For capacity as well as convenience, the hydration back packs are a perfect back pack, especially for the large number of modalities included within MTB. These back packs are so convenient, that some of these hydration back packs are designed exclusively for storing H2O, with a specific pocket for the phone or keys.
For those that want to avoid having to carry a back pack, you could opt for a bag for your bike. These are extremely practical if you just want to carry some spares like a chamber, pump or Allen Keys. The wide variety of bags will allow you to place them wherever is more practical: frame fit bags, under the saddle, in the saddle bags, etc.
