    • Great product
Color: Black
Great product for very useful concept for hydrating on the go. Works as intended. Plenty of room for packing other carry-on items. Durable material.

Perfect product and great delivery. Don't want to say more or it won't meet Amazon's guidelines, even when complementing .

    • Functional day pack.
Color: Black 2.0
This is a great field pack for day hikes. I bought it for field work (wildlife biologist, upper Midwest). My summer field work involves hours (4-6 at a time, 12 hours a day) of walking prairie habitat in the mid-summer heat (90-100+ degrees). This allows me to carry enough water (I also carry two small bottles) plus two field manuals, note book and writing instruments, multitool, flashlight, extra head coverings (boobie hat, keffiyeh x 2), and a few meal bars and drink powder packets. Black color gets hot, but I didn’t want camouflage so I don’t look like a poacher. The hook and loop is nice for reflective/name tape. Adjustable straps and straw ports make this functional and adaptable for anyone. Material is all-around string and durable. If you are looking at hydration packs and you are looking at CamelBak, you probably already know it’s the go-to. ... show more

    • Love CamelBak

I love CamelBak products. This was purchased to hold my water and other items while participating in annual summer camps.

    • Great Product
The Camel Bak Hydration Pack 100 oz. Mil Spec Crux Reservior works great with enough extra room for items for a long day hike or hunt. Mine came late but that wasn't a big deal. It was shipped during the global internet disruptions of July 2024. However the bite tube did leak. I noticed this a few days after it was delivered. Camel Bak has a, got your back lifetime warranty. So I called them no answer. Emailed them and they responded but about 2 weeks later. In the meantime I submitted their warranty claim form. I don't know why I didn't use it first. In about 3 days I received an email stating that my isuue was resolved but not saying how. A few days later I received another email saying my item was shipped. Within 2 weeks I not only had a new bite tube but an entire insulated tube system which of course includes the bite tube. Lesson learned, if you have any issues with the Camel Bak, use their warranty claim form. A great product and company that I highly recommend. ... show more

    • Nice small pack/hydration pack,
I purchased this for day hikes and camping, of course the bladder alone is almost worth it but it also has PLENTY of pack space for pretty much anything you would use during a day trip. A tablet, power bank, small solar panel, lunch stc. . It's also very comfortable and light to wear - I've worn it between four and eight hours on several occasions and I'd almost forget I had it on. Not to mention it's very easy to get the bladder in and out to clean and fill/empty it. Camelbak is one of the more expensive brands, but to me it's worth it because I'll get my monies worth out it. ... show more

    • Great camelbak with storage.
Color: Multicam
Great product. I have 2 of them. Great storage options for items. I use when going to Disney. Bought a after market neoprene cover for the bladder to keep it colder longer.

    • Great pack -stiff straps!
Color: Black
I had one of these (an older standard camo model) back when I was in military school. Who knows what happened to it - but I bought an Osprey pack which I used for the last 10 years or so to replace it. The Osprey pack is starting to wear a bit and honestly I liked the MULE better and so I went with the all-black version this time. Super happy with it though the straps are a bit stiff out of the gate. As it's colder now I'm not wearing it as much (as I'm not hiking as much) but they were pretty rough on my shoulders the first couple days. I know it'll break in - but that's just why it's 4/5 rather than 5/5 stars. Excellent day pack for what it is. ... show more
