I used an MSR bladder (i think 2 liter) thats red colored about 15 years ago and the hose / bite valve that came with it broke and leaked after little use. I still have the bladder with a simple cap on it to (no tubing or bite valve) and its solid . The camelback 100 oz that came with my mil HAWG has been my primary for 8 years with no problems. The source bladders look nice and I plan to try one.
