The larger capacity, the wide opening and the locking cap make this the best soft flask in my opinion. I bought three of them with the LF 5L vest and they fit in the pockets in back along with the two chest flasks up front beautifully. Max hydration capacity without a bladder.

Great size flask and locking cap is genius
I can throw two or three of these in my vest and have very specific hydration that won’t spill on my other stuff!
