Review on Eighty Days Tactical Hydration Multitool by Matthew Miles

I've used the backpack twice so far, it's big enough for bike repair tools and some snacks when I need them. The opening in the hydration pouch is large enough to fit ice cubes to keep the water cool when you're out for a long time. The packaging itself is a little fiddly to clean unless you have fishing wire and cotton balls to clean the snorkel, some water will get stuck in there for days.
