If you're planning on heading outdoors and hitting the trails at all this summer, one thing you should always keep in your pack is a water filter straw. These handy devices are packed with filters to remove 99.99999% of waterborne bacteria, making water you find in lakes and streams safe to drink whether it's clean or dirty at first. You've probably already heard of the LifeStraw if you're an avid outdoorsman (or woman), but if you're looking to save a bit on the purchase of such a device, then it's time to consider the Etekcity Water Filter Straw. It's usually priced right around $18 just like the LifeStraw, but today you can snag one for only $9.99 by entering promo code YKIL47JL during checkout at Amazon. That's a small price to pay for something that could end up saving your life one day.
