Hydration Packs vs Bottles - What Should You Use?
There are two schools out thought out there when it comes to carrying water on an outdoor adventure or athletic outing.
Traditionally people have lugged around bottles made from plastic or stainless steel either by hand, in a traditional backpack or on specialty waste belts with water bottle holsters.
But here are a few reasons why you should trade in that water old bottle for a modern hydration pack:
Extra Storage: You can get a hydration pack with extra pockets and zip up compartments designed to carry small or large amounts of gear like a compass, snack food, wind breaker or even extra water bottles.
Durability: The water bladders or reservoir that comes with hydration packs nowadays are made from extremely durable plastics that are BPA free (a bad cancer causing substance) and puncture resistent. Some manufacturers like Camelbak warrant the reversoir for life.
For this fact alone you should beware cheaply made knock off hydration packs, they usually have vastly inferior water bladders made from thin plastic.
Collapsable: Unlike traditional water bottles the water bladder in a hydration pack is not rigid and collapses as you drink from it so it takes up less space and volume. Plastic and stainless steel bottles are rigid and retain there shape when empty.
If you don't want to lug around a hydration pack (this typically applies to most runners) you still have a couple of options so you don't have to carry water bottles.
Camelbak also manufacturers hydration fanny pack style hydration packs that have a small water reservoir just like in the larger pack models but it fits nicely around your waist. Of course the trade off on these style packs are very small and can't carry much more than a walet, set of keys and a snack bar or two.
You can also get a waist back designed to carry one or more traditional water bottles. This allows you to re-use and clean out the water bottles while still being able to pack along some extra water in a very lite weight pack.
