  • Low Profile Reservoir

    Durable Low-Profile Design

    An RF welded center baffle gives the Mil Spec Antidote a low profile for better packability and maximum stability for operating in tight spaces. All Mil Spec Antidote reservoirs are made from reliable, 3-layer polyurethane with HydroGuard™ Technology.

  • Easy open 1/4 turn cap

    Our air-light fill port has the largest opening on the market - making it quick and easy to fill and clean the reservoir. Opening and closing the cap is now more simple and secure than ever, with our intuitive 1/4 turn cap that's impossible to overtighten.

  • Quick Link

    Quick Link™ System

    Quick Link™ tube disconnect and auto shut-off make it easy and convenient to refill your reservoir as well as route your tube without hassle.

  • Big Bite™ Valve & Cover with QL Hydrolock

    Our patented Big Bite™ Valve self-seals after each drink to eliminate annoying drips and delivers a high flow rate with no moving parts to break or get gummed-up. QL Hydrolock™ provides easy to use single handed flow shut off with positive lever action.

  • Drying Arms

    Integrated Dryer Arms

    Lightweight, integrated dryer arms make drying your reservoir a simple and thorough experience. Dryer arms fold out from behind the fill port and tuck away cleanly when not in use. (*Hanging Hook Sold Separately. Not all Antidote Reservoirs come with Dryer Arms. Check Product Details.)
