small, perfect for me

  • Familiarity:I've put it through the wringer

perfect for me


Tactical use

  • Familiarity:I gave it as a gift but have feedback to share

I bought this for my wife to use. She's a member of the tactical team for our county sheriff department. She uses it weekly during training and has used it on a few call outs. Fits well and holds enough water to keep hydrated. No complaints at all.


Great for quick trips

  • Familiarity:I've used it several times

The 50oz capacity is perfect for about 90min. The pocket has room for a phone, keys or a few gels. It is very tiny. You will not fit anything that you don't have to have. This reservoir doesn't have the quick connect like the bigger ones do, but the fill port is the same.

Can you put ice in your camelbak.

Can you put ice in your camelbak.

Hey there! I typically will put some ice in my camelbak on really hot days.

Absolutely. There's no risk of damage to the bladder or tube as long as you don't put the bladder itself in the freezer. But feel free to fill it with ice cubes and water. Keep in mind that with the more minimalist ones like this one, rather than the bigger backpack types, you may be able to feel the ice cubes through the fabric, which could get annoying, so in that case it might be best to just refrigerate a few bottles of water overnight and pour them in in the morning.

Best Answer

I put ice cubes in my Camelbak for the hotter half the year. Sometimes I can feel the coolness on my back through the backpack and I like it when I'm riding my bike in 80-100 temperatures or hiking. You will hear the ice cubes jostling around in there, but I don't mind if it means I can have cool water for longer.


Awesome to ride with

  • Familiarity:I've used it several times

I use it on my rides and its just great, light weight and keeps the water cold during the rides!


Great bag

    It holds just the right amount a water for my morning trail runs. Keeps the water cold, its light weight


    Cold Water!!

    • Familiarity:I've used it several times

    I love this pack because if I am going on a short hike, or a run, it is the perfect wait and size. It also keeps the water amazingly cool which in this weather is amazing. Yes I would strongly recommend this to anyone ! I love Camelbak, and all of my hydration packs are from this company.


    It must be a user design flaw. . .

    • Familiarity:I've used it once or twice and have initial impressions

    I read the other reviews of this product. So I decided to get it for a two day 150 mile bike ride I was undertaking. I figured I could use it in addition to my bottles. Anyway, I liked the size, the look, the weight and everything about it but one. It seemed that I got more liquid on me than in me. I had heard that these things leak. Well that was my experience and, unfortunately, it was so cold in the morning of the first day of my ride that the dripping water was very unwelcome. So I gave it to a friend who loves it. Go figure.


    Great pack, minor design flaw.

      This little bladder pack is perfect size for training rides where you just want to go out, get your heart-rate up and get the job done. Small zipper holds a gel or two, keys and a phone. I like the mesh straps as they help to keep the shoulders from heating up.

      I will echo the lack of a chest-strap complaint. I think that regardless of the size of the pack a sternum strap is necessary. It is such a simple addition but it provides the user with increased pack stability.

      That being said, if you go to your local craft store you can get buckles, and some webbing and make your own inexpensively and quickly. I think that a few companies may also sell pre-made units.

      Also, the bladder is essentially suck inside the pack. There is an intricate folded panel system holding the bladder in, thus making it difficult to remove for drying purposes. The saving grace of that issue is that the widemouth design allows you to towel dry the inside.

      Aside from those small little issues, this is a great stripped-down pack.

      My husband has this version and he routinely removes the bladder to use in a larger hydration-compatible day-pack for longer hikes.


      Purely for Hydration

      • Gender:Female

      I used this while training for a half marathon in Jamaica. It made my 10+ mile runs much more bearable, as exercising in a humid tropical environment is a totally different

      beast with the amount of sweat that you produce. I had never run with a hydration pack before, so the loudness of the water sloshing around in there with each step was rather surprising at first. But after I figured out that hooking the hydration tube between the shoulder straps across my chest held the pack tightly to me, this thing was great. I wish there was an actual strap there for this use, as unhooking the tube for a drink was rather annoying, but it was that or the pack bouncing all over the place. This thing saved me from horrible dehydration alongside a highway in Jamaica, so it did what it is designed to do.



        I purchased this size because I needed something lighter than a 2L and something that would hug my back.

        I Love this thing! the 1.5L bladder is just enough for about 2 hours. I usually ride for around 6 hours so I ride out to refill it but on the trails it is great. super light and the front pocket is just big enough to put my phone in.

        the only downside that I have for this is it does not have a buckle on the front ( as the larger ones do) so when I get air it slides up on my back a bit.

        But besides the one downside I think it is great and perfect for what I use it for.


        Camelbak Hydrobak

          I love this Camelbak the most out of the 3 I have. I use it when riding dirt bikes or racing in the woods. Fits over my chest protector and holds my essential tools, fix-a-flat, and a spare tire tube and Ive had no issues with it. When its full I can easily go nearly a day with it, it seems like you never run out of water! I definitely Recommend this product to any outdoor enthusiast!
