So many storage options
This vest is perfect for those of us who want to take all the things on hikes or runs. Like I might need a separate pocket for my keys than from my chews or my chapstick. I need a pocket I can easily access for putting my phone in and out quickly.

Decent pack with lots of pockets however sizing is off
Decent pack for 100milers. The pros are great pockets to hold your nutrition and gloves/hats; plenty of storage to go the distance; durable pack vs the Salomon packs. The cons is the front bottle pockets are too big for other brands such as Salomon/Ultimate Direction soft flasks. It’s best for plastic bottles vs the collapsible bottles. Another con is the sizing is off: my chest size is 41/42 inches thus a large pack however I can pull both sides of the vest and meets each other….. I would go with a medium; and the last con is the fastenings gets loose within a hour of running and then have to adjust and tighten again. I wouldn’t but again.
