CamelBak's OMEGA Water Beast™ Reservoir is the ultimate protection for an operator's water supply. The reservoir's increased durability, OMEGA wide mouth opening, rugged texture and HydroGuard™ Anti-Microbial Technology ensure the delivery of safe, clean water during extreme operational situations. Includes Big Bite™ Valve.

CamelBak's Reservoir's are made of an incredible polyurethane material that is 1.6mm thick! It can withstand near boiling water and can actually be frozen solid with water inside. That means it will not burst - so you can be as tough on it as you want without worry.
