The HRT HydroMax Pack Zip-On Back panel was designed with the purpose of versatility. The large single pocket design allows users to properly carry hydration along with supplies that can be easy access for team members.

The lower outer pocket can hold your administrative items or additional supplies with the top outer pocket is able to accept any of our maximus line of inserts to configure the pouch for your specific needs.

This is the ultimate solution for swapping loadouts with one core plate carrier and numerous rear Zip-On panels to suit any mission. Secured attachment with YKK zippers and button loops, our Zip-On panels provide several options for carrying extra gear, ammunition, and equipment for your operational needs.

    Have not received this item yet but will update review upon receiving item

    Just received my pack and it is better than I thought. I was able to fit the maximus panel in it with no problem and am able to hold a set of bolt cutters in the back with no problem. I do not yet have a bladder for it but was told by HRT it takes most 1L and 1.5L bladders and the CamelBak Crux Lumbar 3L bladder and plan to get one. Plenty of room on the back 2 pockets for I.D. Patched and morale patches. Overall I am very happy with the quality and design of this pack. Even though it took much longer to get than anticipated it is well worth the wait.

  3. Clay Johnson

    The gear is awesome! The customer support and 6 month ship time sucks.

  4. Rodney Casen

    Couldn’t have asked for anything better

  5. Jeffery C.

    It’s exactly what I expected. And easy to put on and take off if you wanted too.

  6. Christopher T.

    Excellent addition to my rig. Secures with straps and zippers so it isn’t going anywhere. Great product, very pleased so far!

  7. Kyler

    Would like it if it held a larger bladder otherwise great product

  8. wyatt m.

    Very thoughtful hydration pack. Id love to see a standalone version to apply to other PCs.

  9. Ray F.

    It’s like a 3 cell micro backpack with a section for hard or soft camelbacks. Excellent. Please start selling hard camel backs for this.

  10. Christopher D.

    Great addition to the RAC

  11. anthony

    works wonderfully with the plate carrier.

  12. Esward PITTMAN

    Great pack 👌 well made.

  13. Colton Howard

    Nice product lots of room. Could use less velcrow and more molle loops tho.

  14. Eric Daniel

    Well made and easy to attach. However I did get the impression from pics that it came with a water bladder and drinking tube but no big deal. Nice products from HRT.

  15. Robert W.

    It is roomier than I expected but not bulky at all. Honestly I could not be happier with it if I tried. Very sturdy and easy to attach and extremely secure.

    Best of the best

  18. Chris C.

    Excellent build quality and a very nice concept using zipper integration with the carrier. Use lightweight armor and this is comfortable enough to wear all day. Also purchased the MOLLE placard for magazines and it was perfect.

  19. Nicholas Murtha

    Best attachment you can buy for the back of it. Fits a bladder super easy

  20. Tallon C.

    Great products. Good internal originization.

  21. James

    It says it will fit a 3L lumbar crux bladder, which is true, as long as that’s the only thing you want in the main pocket. If you want to carry anything else you’ll need to downsize to a smaller bladder. Hydration is important so I like to stick with the bigger one, unfortunately now I don’t have quite as much room as I had hoped for other supplies.

  22. Jeremy

    Love it

  23. James Castillo

    Well made, fits great, outstanding feedback and customer service. 10 out of 10 would shit here again!… I mean shop. Shop here again!

  24. Travis Fox


  25. Renato Corona

    Love that it’s slim, but has the option to expand!

  26. Terence L.

    Hydro max is a perfect addition to my HRT RAC plate carrier, an ingenious design and functionality. I wouldn’t mind some awesome swag gear 😉Thanks again HRT

    Super high quality, ultra strong material. Couldn’t be happier with my “Gucci” gear from HRT!

  28. Edgardo

    Excellent work here. This hydration pack is great. It has actual space for usage. I have other hydration packs from different companies & this is by far the best.

    Zip on attachment is a game changer. Excellent product.

  30. xavien fernandez

    Great add on for tools and hydration bladder with and easy and sturdy install

  31. Jeremy

    Exactly what I needed. Tight fit and has the space needed for my kit. Best gear on the market.

  32. Garrett S.

    Quality of this item is exemplary, it is relatively comfortable but certainly is not like you’re just wearing a t-shirt, lol. I am 5’8 150 lbs and the one size fits all type design is in my opinion a little lackluster. If you need to wear an 8×10 plate then you were going to have a lot of material on the sides on the top and bottom and there is no way to adjust and tighten up this loose material. The same goes for other design plates there should be a way to adjust and tighten up loose material. In their description I think they miss the possibilities of the carrier itself, whether it was designed this way I’m not really sure but I was able to replace the maritime buckle from laying over my collarbone and now it has the design of the HRAC. Whether it was designed to do this I don’t know but I didn’t do it and I very much prefer it. Also removing the buckle gave me a little more material to be able to move the carrier up a little bit more. Nothing about this item is terrible but at the same time it’s modularity is lacking in the most important areas which is fit not how much Molle you can put on it.

  33. Richard B.

    As advertised, exultant customer service

  34. Michael Fratto

    Ultimate way to comfortably stay out all day! Plus the extra storage for anything extra is amazing!

  35. Nicholas W.

    Turns the RAC into a backpack

  36. Rebeka S.

    Works great

  37. David Ashcom

    This stuff is very high quality and all well worth the money. Fast shipping too!

  38. Anonymous

    Great back placard, tons of room inside, would recommend over other back. Placards

  39. Charles P.

    High Quality product. Fit the Plate carrier perfectly. Enough room in the zippered pockets for spare batteries, gloves, multitool, bore snake, etc. The main zippered pouch is wide enough for the low profile Source water bladder also. Just the right size overall without being bulky or too large. HRT shipped my order fast also.
    I have already ordered other items.

  40. Dylan S.

    Quality pack have only used it for flex cuffs and radios so far will update when I use it more.

  48. Michael

    Spacious pack

  49. Cody Harrison

    I heard of you guys from Iron Infidel and you guys have thought of everything when it comes to gear, the best plate carrier I own and that I’ve used so far. Very mission adaptable I can gear it up heavily or gear it down to be slick and use for exercise. Highly recommend this carrier

  50. Ryan

    perfect amount of space

  51. Anonymous

    Came extremely fast and was as expected.
