The Camelbak Skeeter hydration pack for kids is the best purchase you can make for getting a child to carry his or her own water supply for hiking or biking.  If you own a Camelbak hydration pack for yourself you've probably already had your child drinking from it and are getting tired of him chewing on the bite valve?  Now you can get the little one his own Camelbak hydration pack.  Camelbak's reccommended age is 5 and up.  We've fit them on kids as young as 2 but kids 3 and up seem to get the idea of working the valve by biting and sucking best.  For older kids the Skeeter works great if it's just being worn for biking and you want something low profile.  There is no storage space though.  If your child is older, 6 and up, and you want something that's going to be more versatile we strongly reccommend the Mini Mule that has a larger reservoir and 159 cu in of storage space.
