Anyone who has spent a lot of time outdoors hiking, camping, cycling, or running knows just how important it is to stay adequately hydrated. Without the right hydration solutions, endurance flags and sustained physical action becomes increasingly difficult. Furthermore, recovery takes longer and can feel less successful as a result of becoming too dehydrated. If the body's mineral balance is not restored, then a person can feel sick and disoriented; this is a dangerous condition when you need to be on point in hazardous or unpredictable territory. A bite valve helps ensure that hydration is always close at hand and convenient to access. However, even the best valves can get worn out from time to time so having a CamelBak Hydrolink™ Hydrolock Replacement Bite Valve is a very good idea. These valves are manufactured from durable plastics for reliable performance every time. They slip right into place and hold securely until they are removed for cleaning or repair.
