Pingora Impulse Hydration Pack

I bought this to compliment my Deuter Ascender. I like the idea of vest up front, pack in the back. The Impulse got my attention because of the hip belt and external pocket, both nice touches. It also handles a 3 liter bladder easily. I found the front pockets not deep enough for a phone or glasses. Both hung out and eventually worked their way out. I dont know yet if I'm sold on the interior compartment design.

Not enough padding in the arm straps, the seam digs into your shoulder

Too little for tall XL hikers
