Feel Secure w/Camelback MilSpec Hydration Reservoirs on Long Day Hikes
There's several reasons why this hydration pack is perfect (for me)! First, it's the perfect size for my hiking/outdoor activities. With the varying sizes available, it came down to how much more weight do I want to carry on a 3-5 hour day hike. At max capacity, the Camelback 85 oz (2.5L) Reservoir weighs 5.3 lbs of water. Together with my gear, 40-lbs of gear is the maximum weight that I prefer to carry in my backpack. Second, this size choice was based on what the recommended amount of water was needed: 16 oz (0.5 liters) /hr. I also want to carry extra water, just in case. So this size met my specific needs. So at 85 oz (2.5L) capacity, this will last me up to 5-hrs of hydration. Third, it's the Camelback brand. This model offers the superior manufacturing specs and quality design features for reliability and durability. I don't want failures staying hydrated with fresh water out in the field, especially on hot and humid days, nor do I want my gear to get wet inside the pack. This model offers that security. Overall, it's performed exactly as advertised and is exactly what I was looking for.

Compatible with Eberlestock’s H7 Dagger Hydration Pack
I predominately use Eberlestock kit for Tactical Operations because their packs have served me well. However, I have not been pleased with the Source hydration reservoirs they include for their hydration systems. Too many issues with leaking and sweating. I decided to replace the Source in my Eberlestock Dagger H7 with this one and I’m very impressed with the upgrade. Haven’t experienced any of the issues like I had with the other brand. For those looking to do the same with their Dagger or other pack model, I highly recommend it. As a note, this 85oz upgrade does fit in Eberlestock’s hydration pockets made for the Source 70oz, plus it gives you a 15oz boost in water capacity. Overall very happy with the purchase and it’s performance. Recommended upgrade.

Fit great in my Timbuk2 backpack!
My pack had loops on the shoulder strap for a hydration pack, but no port or designated spot to hold the bladder. The smaller crux fits in a spare compartment on the front and I can snake the hose through the velcro opening. The hose is long enough to fit through my loops. I love the quick release function too! You can fill the bladder without the hose attached and nothing leaks.

Great for civilians too!
The Crux model replaced my previous Antidote version after several years good service. Love the durability, quality, insulation sleeve and covered mouth piece! However, the “corporate developers” have struck again because the unmarked screw down lid is easy to mis-thread. Update 2022: I got used to being careful about “misthreading” the Crux lid closure so no longer get spilled water over the kitchen counter. The insulated drink tube significantly reduces the tube contents from freezing on winter hikes. Time using this product caused me to raise to five stars!

Perfect Except for Faulty Seal
Works great! Only complaint is that you need to be careful to align cap screw threads to make sure it seals completely once closed. Multiple times it seemed correctly closed but would leak if squeezed or tipped over.

Definitely will buy again

Ich hatte zuletzt 2 aus der „blauen Serie“, die waren schon gut. An dem Trinkschlauch haben sie tatsächlich einiges geändert, was mich an den anderen Störte. Endlich ein abnehmbarer schlauch. Gerade bei langen Touren mit 40L-, oder 70L-Rucksack war das Nachfüllen lästig, weil man nicht nur den Wasserbehälter aus den Rucksack bekommt musste, sondern auch den Schlauch durch die Öffnungen ziehen musste. Jetzt sollte das eigentlich kein Problem mehr sein. Habs nur 1x unter realen Bedingungen…nach einem 30km-Mammutmarsch…testen können, weil ich den Rucksack lehrte. Aber da gab es gar keine Probleme…war aber auch ein sonst leerer Rucksack. Der ummantelte Trinkschlauch. Bisher war es so, dass das Wasser im Trinkschlauch immer etwas aufwärmte, was nicht Schmeckt. Beim Mammutmarsch anfang Mai war es nicht warm, das wasser wurde aber weder Warm, noch spürbar kälter…es blieb bei einer Angenehmen Temperatur. Natürlich sind das nur 2 Kurztests…aber wenn möglich, werde ich nach meiner nächsten 2-Wochenwanderung mehr berichten.
