Take a swig of water out of your CamelBak Womens Charm Hydration Pack to calm your thirst when you hike down Angels Landing in Zion or mountain bike in Moab.
A water bottle cage works OK on the bike leg of your triathlon training session, but it doesnt do much good when you get to the run. Use the CamelBak Fairfax Hydration Pack for both.
The North Face built the Womens Sailfin Hydration Pack with rubberized mesh shoulder straps and a sternum strap, so this pack and the 70oz water reservoir remain snug on your back while you go the extra mile.
