Look for the tag on the outside of specific packs by Burton, Da Kine, Ride and Black Diomond (just to name a few) and the CamelBak-certified sleeve on the inside.
If you’ve ever wished a hydration system fit nicely in your backcountry pack without getting squashed or freezing up, you’re not alone. CamelBak® has seriously addressed this issue and come up with a promotional program to make sure a variety of pack designs are up to par with their own well-thought-out hydration system-not to mention sell more product. The CamelBak Compatible program is their response to snowboard pack makers who wanted to build in a sleeve that would hold a full CamelBak system (not just the reservoir) inside the back panel of the pack. CamelBak approves the design and provides a special hang tag designating that product “CamelBak Compatible.”
