Let's get real. I'm 16 and a guy, therefore I'm pretty rough on gear. This bladder has been through it's paces. Biking, skiing, hiking, Everything. It's been dropped, thrown and everything else. It's durable. The best part is the threads, being the same as a nalgene they fit most all water pumps. A perfect with with my MSR Miniworks.Cleaning is easier than my camelbak bladder. The mouth piece works better too! Definitely a good investment.
