Think of how many plastic bottles this will save, not to mention the sheer convenience of being able to use hotel tap water. It's BPA free and you also don't have to worry about leaching from water just sitting in commercial bottles. I can't wait for the day that bottled water is obsolete and here is something that will really help the cause.
For backpackers and campers, there's a pre-filter (sold separately) that you can use to filter out debris. Beyond that, you can filter your stream water and be safe from microbes.
Everyone should ideally have some sort of water filtraion device, Hurricane Sandy is a great reminder of this. The handier and easier to use, the better.
The magic is right under the cap where the UV bulb is housed, you just push the button and it zaps your water and an LED screen let's you know it worked. You recharge the cap with a USB charger--plug it right into your laptop or use a wall charger--and you get 80 treatment cycles per charge. There's a regular cap to replace the UV cap when not in use, and you can also use other CamelBak caps if you prefer the kind with the spout. Find it HERE.
