Clean well before first use 

  • Remove the bite valve & wash the bite valve thoroughly in warm soapy water

Water back pack

Very easy to order and was delivered the next day. I was looking for a back pack small enough to take the water pack and maybe keys and credit card Thus fits the bill perfectly for cycling when not wanting to carry too much. It’s well made and does the job.
