Source is in my opinion the best hydration bladder system. With the wide opening its easy to clean and to push the last air out after filling. The source quick connectors are easy to maintain and the bladder and hose stay clean for a long time. The bladder has a baffle to keep the form stable and avoid sloshing.I like the "Helix" bite valve better than the "Storm" one, but its easy to change.

These are amazing!!! Just the perfect size for a day hike or even just to drink from at work, lol. It seems to be really durable. We bought the nozzle addition so we can easily refill w/ a hose or water bottle w/ out removing our packs, .. So perfect! We refilled once directly from a spring and the water stayed super cold for the entire day. I just love it! Water bottles are now a thing of our past. :)

Buena calidad

So I'm using this hydration bladder inside the Agilite AMAP III assault pack, and it fit's inside it pretty nicely.Also, the bladder itself is pretty rugged, no leakages so far.

Marca già super conosciuta ottimo materiale, l’acqua non puzza anche se lasciate per un po’ di tempo è facile da pulire, il beccuccio è ottimo

I used to hate using drink bladders, until I purchased this one from Source. The water flow is fast and drinking is easy. Highly recommended.
