Achieve Peak Hydration With the Multicam OCP ThermoBak

The Multicam OCP ThermoBak is the perfect hydration pack for the military minimalist. Carry the three-liter hydration pack on your next military operation to improve the consistency of your water intake. Take advantage of the impressive characteristics of the ThermoBak, such as:

  • External fill: The addition of external fill means you can fill and refill the hydration reservoir without removing the bladder from the pack. Save time while you’re on the move with quick refills for optimal hydration.
  • Enhanced endurance: The ThermoBak can persist in the most challenging environments. The construction uses 500D Cordura, creating superior strength and water resistance. You won’t need to worry about wear and tear, allowing you to focus on your critical operations.
  • Versatility: You can carry the ThermoBak independently, but you can also use the D-rings to integrate the hydration pack to packs or armor with MOLLE webbing.
  • Quick access and flexibility: The quick-release buckle detaches quickly when you need a refill or want to share water among your unit. You can create a comfortable and secure fit using the adjustable straps and strap management features.

Stay Happy, Healthy, and Hydrated With the ThermoBak

Military operations are critical to the safety and security of our country, and our troops can’t focus when they’re dehydrated. The ThermoBak can help members of the armed forces increase their fluid intake to improve their health and energy levels.

You can take the ThermoBak wherever you go, whether you’re working or enjoying leisurely outdoor activities. Stay on top of your health and well-being with the ThermoBak in tow.

Consider the AMBUSH for More Storage

The ThermoBak is an excellent hydration companion, but you may want more storage for your belongings. The Multicam OCP AMBUSH by CamelBak offers the same hydration capabilities but with more storage potential. Use the multiple zippered pockets to stow your essentials while you’re on the move or performing critical tasks.

    Rugged, ready to go. When you don't need to carry a lot on a hike, this is what you need. Room for wallet, keys, so your pockets are empty.

    Best water source

    Posted by Anthony on Jun 6th 2016

    The Camelbak is the best product on the market for a water source. I use this product all the time and have never had any issues. It holds up well under constant use.

    The Best

    When the Army issued this to me they gave me a cleaning kit with it and it was a life saver. These have always been the best in hydration.

    Works great

    I use this little guy everytime I just need fluid... A lot of times I have to switch it out for a bag with pouches, but it's a life saverwhen all I need is water. Never leaks and jumped with it more then 10 times and still hasn't burst on the dropzone. Great buy!

    Helped Win the War!

    I got issued this at CST, from Ft Dix. This sucker was a life saver. I had it clipped to my IOTV, and it went everywhere with me. I would usually just put water in it, but occasionally I would get CRAZY and put some MRE fruit punch in there. I was able to wash it out really easily with the Camelbak cleaning kit. I found it very easy to fill, too.

    Used this product during CAST training...easy to fill and use!! Kept water cool and straps were long enough to fit comfortably over battle rattle. Great product!
