SOURCE source widepack 2l

The new Widepac LP Low Profile fits most packs and keeps its low-profile shape no matter how full or empty the reservoir is. The baffle wall down the middle of the reservoir maintains the low-profile shape at any water level.
Water is also distributed evenly over a wider area of your back compared to our standard Widepac Hydration System, adding comfort and optimizing your pack’s storage space and weight distribution.
The Low Profile version of the Widepac features all the benefits of SOURCE Hydration, giving you a low-maintenance hydration system that adds no plastic taste to your hydration.
